2. Remove the paper tension unit as shown below.

3. Remove the locking clip.

Store the clip with the other packing material in case you ever need to transport your printer.

1-4 Setting Up the Printer

Choosing a Place for the Printer

There are several important things to consider when selecting a place to set up your printer. Keep the following in mind:

Place the printer on a flat, hard, stable surface. A soft surface, such as a padded counter or carpeted area, will block the ventilation slots and may cause overheating.

Place the printer close enough to the computer for the printer cable to reach.

Leave adequate room around the printer to allow for easy printer operation and maintenance, and for unrestricted flow of air around the printer.

Use a grounded outlet; do not use an adapter plug.

WARNING: Avoid locations that are subject to direct sunlight, excessive heat, moisture, or dust,

I I

Avoid electrical outlets controlled by wall switches or automatic timers. Accidental interruption of power can wipe out information in your computers memory and in your printers memory.

Avoid using outlets that share a circuit with large motors or electrical appliances; this could cause fluctuations in line voltage.

Keep the entire computer system away from potential sources of electromagnetic interference such as loudspeakers or the base units of cordless telephones.

Setting Up the Printer 1-5

Choosing a Place for the Printer

The illustration below shows a good printer location.

Note: Before using a printer stand, read these requirements and suggestions.

l The stand should be able to support at least twice the weight of the printer, or approximately 36 pounds (16 kilograms).

l Never use a stand that supports the printer at an angle of more than 15 degrees from horizontal.

l With a cut sheet feeder, your printer must be kept level.

l If your paper supply is positioned below the printer stand, make sure there is enough clearance to keep the paper from catching on the underside of the stand. Also, make sure the distance between the stand supports is wide enough for the paper you are using.

l Position your printers cables so that they do not interfere with paper feeding. If possible, secure the cables to the printer stand.

1-6 Setting Up the Printer

Assembling the Printer

After youve decided on the best place to set up your printer, the next step is to install the platen knob.

WARNING: Be sure to remove the locking clip as described in

Installing the Platen Knob The platen knob is used to feed the paper manually in the event of a paper jam or other paper feeding problem. The platen knob is packed in an indentation in the printers white foam packing material.

1. Insert the knob into the hole on the printers side and rotate it slowly until it slips onto the shaft.

Setting Up the Printer 1-7

Assembling the Printer

2. Push firmly on the platen knob until it fits against the printer case.

CAUTION: Do not use the platen knob to adjust the position of the paper. This interferes with the automatic paper loading system and may cause a paper jam.

Installing the Ribbon Cartridge Your printers ribbon cartridge is designed for easy installation and removal. Before installing the ribbon cartridge, make sure the printer is turned off.

1-8 Setting Up the Printer

Assembling the Printer

Install the ribbon cartridge as follows.

1. Slide the print head to the middle of the printer.

CAUTION: Never move the print head while the printer is turned on because this can damage the printer. Also, if you have been using the printer, the print head may be hot; let it cool for a few minutes before touching it.

2. Turn the ribbon-tightening knob in the direction of the arrow. This removes slack in the ribbon and makes it easier to install.

Setting Up the Printer 1-9

Assembling the Printer

3. Hold the ribbon cartridge by its handles and push it firmly down into position, making sure the plastic hooks fit into the slots.

Note: Press lightly on both ends of the cartridge to make sure the plastic hooks are properly seated.

4. Use a pointed object, such as a ball point pen, to guide the ribbon between the print head and ribbon guide while you turn the ribbon-tightening knob to help feed the ribbon into place.

Assembling the Printer

5. Slide the print head from side to side to make sure it moves smoothly. Also check that the ribbon is not twisted or creased.

6. Fit the rear notches of the paper tension unit over the pins of the printer. Lower the unit, pressing on both sides to lock it in place.

Setting Up the Printer 1-11

Assembling the Printer

Attaching the Paper Guide When you use single sheets, the paper guide helps to feed the paper smoothly and efficiently into the printer. Attach the paper guide using the following procedure.

1. Place the paper guide on the printer as shown below.

2. Raise the paper guide until it locks into place.

1-12 Setting Up the Printer

Assembling the Printer

Note: To lower the paper guide, lift up slightly to release it from its locked position; then gently lower it down onto the printer.

3. Attach the printer cover by fitting the hooks on the cover into the notches at the front of the printer and tilting the cover back into place.

Setting Up the Printer 1-13

Testing the Printer

Now that your printer is fully assembled, you can use its built-in self test function to see that the printer is working correctly before you connect it to a computer. You should perform this test to make sure that your printer was not damaged during shipping and that the ribbon is correctly installed.

Before running the self test, you need to connect the printer to an electrical outlet and load a sheet of paper.

Plugging in the Printer 1. Make sure that the printer is turned off.

1-14 Setting Up the Printer

Testing the Printer

2. Plug the power cable into a properly grounded electrical outlet.

Running the Self Test The self test can be run in the draft or Letter Quality mode, depending on which button you hold down as you turn on the printer. Although the self test can be run with continuous paper, use single-sheet paper now because single-sheet loading is easier.

1. Make sure the printer is turned off.

2. Push the paper release lever back to the single-sheet position.

Testing the Printer

If the Self Test Does Not Work If the self test does not print properly, check the control panel and the print head area. If paper is jammed, turn off the printer. Then remove the paper using the platen knob and load a new sheet. Make sure that all packing material and shipping restraints have been removed from inside the printer. See the Removing the Protective Materials section in this chapter for information on removing the locking clip. You can also see Chapter 7 for further information.

Problem Solution

The printer sounds like it is printing, but nothing is printed.

The test did not print when you pressed the ON LINE button.

The ribbon may not be installed properly. Turn off the printer, reinstall the ribbon cartridge, and then tighten the ribbon by turning the ribbon-tightening knob. Make sure the ribbon passes between the print head and ribbon guide. See page 1-10.

The ribbon may be worn. Replace the ribbon cartridge. See page 6-5.

Turn off the printer and repeat the self test. Make sure you hold down the FORM FEED or LINE FEED button the entire time you are turning on the printer.

Turn off the printer and disconnect the cable from the host computer. Try the self test again.

If the printer still does not print the self test correctly, contact the store where you purchased your printer or call the Epson toll-free number (1-800-922-8911).

1-22 Setting Up the Printer

Connecting the Printer to Your Computer

If the self test printed correctly, you are now ready to connect the printer to your computer.

If your computer has a parallel interface and you have a suitable shielded cable, you should be able to connect your printer immediately. The steps below describe how to connect the parallel interface cable.

If your computer requires another type of interface, you need to install an optional interface board. See the Interface Boards section in Chapter 5.

If you are not sure which type of interface cable is required, see your computer manual.

The Parallel Interface Connect the parallel interface cable as described below:

1. Make sure that both your printer and computer are turned off.

Setting Up the Printer 1-23

Connecting the Printer to Your Computer

2. Plug the cable connector securely into the printer.

3. Squeeze the wire clips together until they lock in place on either side of the connector.

1-24 Setting Up the Printer

Connecting the Printer to Your Computer

4. If your cable has a ground wire, connect it to the ground screw beneath the interface connector.

Setting Up the Printer 1-25

Setting Up Your Application Software

Now that you have set up and tested the printer, you should make sure that it works with your application programs.

Most application programs let you specify the type of printer you are using so that the program can take full advantage of the printers features. Many of these programs provide an installation or setup menu that presents a list of printers to choose from.

If your application program has a printer selection menu, use the instructions below.

Choosing From a Menu Because the family of Epson printers shares a great many commands, you can use an application program even if it does not list the ActionPrinter 4500 on its printer selection menu. If the ActionPrinter 4500 is not listed, choose one of the following printers. They are listed in order of preference.

LQ-1010 LQ-1050 LQ-2550 LQ-2500 LQ-1000 LQ-1500

If none of these printers is listed, select the first one available on the following list:

LQ LX Epson printer EX RX Standard printer FX M X Draft printer

To use all of the features of the printer, however, it is best to use a program with the ActionPrinter 4500 or an LQ printer on its menu. If your program does not list the ActionPrinter 4500 or an LQ printer, contact the software manufacturer to see if an update is available.

Paper Handling 2-1

Selecting a Paper Feeding Method

The paper release lever on the printer has three positions for use with the various methods of paper feeding. Make sure the paper release lever is set to match the desired paper feeding method.

The lever positions are marked by three icons, as described below.

Single-sheet mode: When you load single sheets from either the paper guide or from the optional cut sheet feeder, the lever should be set all the way back to the single-sheet position.

Push tractor mode: When you load continuous paper with the built-in push tractor, the lever should be set in the middle, which is the push tractor position.

Pull tractor mode: When you load continuous paper with the optional pull tractor, the lever should be set all the way forward to the pull tractor position. Even when you use the built-in push tractor with the pull tractor, you must set the lever to this position. Select this position only if you are using the optional pull tractor.

2-2 Paper Handling

Using Single Sheets

Your printer can accommodate single sheets with a width of 7.2 inches or 182 mm to 14.3 inches or 364 mm.

If you do most of your printing on single sheets, you may find it more convenient to install the optional cut sheet feeder. This option automatically inserts a new sheet and can hold up to 150 pages. For more details, see Chapter 5.

Loading Paper 1. Push the paper release lever back to the single-sheet position.

Paper Handling 2-3

6. Press the ON LINE button to set the printer on line. When the ON LINE light is lit, the printer can accept data from your computer.

You are now ready to begin printing.

Reloading During Printing When you print a document of more than one page using single-sheet paper, the printer stops printing when it reaches the bottom of the page. When this happens, the ON LINE light either goes off automatically or remains on, depending on your application program software. If the ON LINE light remains on, the first thing you should do is press the ON LINE button to take the printer off line.

Once the ON LINE light is off, remove the sheet that has just been printed (if necessary, press the LOAD/EJECT button to eject the page) and load a new sheet. Press the ON LINE button to start printing the next page and follow any additional prompts from your software. Be sure that the page length or form length setup in your software matches the number of lines that can be printed on your paper.

2-6 Paper Handling

Using Continuous Paper

The push tractor built into your printer is remarkably easy to load and operate. Its low-profile design takes up little space and can handle paper up to 16 inches or 406 mm wide.

Positioning Your Continuous Paper Supply An important consideration for achieving smooth and trouble-free paper feeding is the position of your paper supply.

Three ways of positioning your printer and continuous paper supply are shown below.

Paper Handling 2-7

Using Continuous Paper

Be sure to align the paper supply with the paper loaded in the tractor so that the paper feeds smoothly into the printer.

Printing on Special Paper

In addition to printing on single sheets and continuous paper, your printer can also print on a wide variety of paper types, including multi-part forms, labels, and envelopes.

Before printing on special types of paper, you need to change the paper thickness setting.

I!!7 WARNING: When printing on multi-part forms, labels, or envelopes, make sure that your application program settings keep the printing entirely within the printable area.

For multi-part forms and labels you should not print any closer than one-half inch from either side of the paper.

For information on the printable area for envelopes, see page 2-31.

The Paper Thickness Lever To accommodate various thicknesses of paper, your printer is equipped with a paper thickness lever that can be set to eight positions. These positions are identified by a scale on the printer next to the lever. (See the chart on page 2-26.)

3. Reattach the printer cover as shown below.

I!!!!!? WARNING: Always return the lever to position 2 when you go back to printing on ordinary paper. Continuous printing with the lever set at a position higher than 2 can shorten the life of the print head. Also note that printing past the edge of envelopes, multi-part forms, labels, or thicker-than-normal paper can damage the print head.

Multi-part Forms With the built-in tractor unit, your printer can print on continuous multi-part forms. You can use multi-part forms that have up to three parts including the original. Make sure you set the paper thickness lever to the proper position; see the table on page 2-26.

Paper Handling 2-27

Printing on Special Paper

Except for the paper thickness lever setting, you load multi-part paper the same way as continuous paper. For details, see the section on loading continuous paper in this chapter. Also see the sections on setting the loading position and page length in Chapter 3.

CAUTION: Multi-part forms should not be used with the single-sheet feeding system or the optional cut sheet feeder.

Labels If you need to print labels, always use labels mounted on a continuous backing sheet with sprocket holes for use with a tractor. Do not try to print labels as single sheets because labels on a shiny backing sheet almost always slip a little.

2-28 Paper Handling

Printing on Special Paper

You load labels the same way that you load continuous paper except that the paper thickness lever must be adjusted for printing labels. See the section on loading continuous paper earlier in this chapter. For the correct paper thickness setting, see the table on page 2-26.

WARNING: Never feed labels backward through the printer. Labels can easily peel off the backing and jam the printer. Therefore, never use the LOAD/EJECT button to eject labels. Also, never use the short tear-off function with labels. (Be sure to set DIP switch 2-2 to off .) If a label does become stuck in the printer, call the Epson toll-free number (1-800-922-8911) for assistance.

Since labels are especially sensitive to temperature and humidity, always use them under normal operating conditions. Dont leave labels loaded in the printer between jobs; they curl around the platen and may jam when you resume printing.

Paper Handling 2-29

Printing on Special Paper

Envelopes You can feed envelopes individually using the single-sheet loading feature. Before loading envelopes, adjust the position of the paper thickness lever according to the table on page 2-26. For details on paper handling, see Using Single Sheets on page 2-3.

When manually feeding an envelope, you may have to push it down slightly while pressing the LOAD/EJECT button to get it to feed properly

CAUTION: The printable area for envelopes is shown on the next page. The print head must not go past the left or right edge of the envelope or other thick paper. Make sure that your application program page setup keeps the printing entirely within this printable area.

Setting the DIP Switches

The DIP Switch Functions

Auto line feed When auto line feed is on (DIP switch 2-4 on), each carriage return code (CR) is automatically followed by a line feed code (LF).

Input buffer capacity The input buffer stores data from your computer. If you want to free your computer for other tasks while the printer prints, change the setting of switch 2-5 to 8 KB (on). Before using user-defined characters, however, be sure to set the input buffer to 1 KB (off).

Tear-off mode When DIP switch 2-2 is on, the short tear-off mode is on. This feature automatically advances continuous paper to the tear-off position, and then reverse-feeds the paper to the loading position. See the section on using short tear-off later in this chapter.

01I CAUTION: Do not use the short tear-off mode with labels.

Print direction of multi-pass characters Multi-pass characters are normally printed unidirectionally. If DIP switch 2-6 is on and ESC U0 is input, multi-pass characters are printed bi-directionally.

Page Length

When the setting of DIP switch 2-1 is off, the page length is set to 11 inches, or 279.4 mm. When it is on, the page length is 12 inches, or 304.8 mm. Be sure to set the page length to match the paper you are using.

Other page lengths can be set using the commands ESC C and ESC C 0. See the Command Summary in Chapter 9 for details.

If you are using the built-in push tractor, you can also select 8.5 inches as the page length by using the control panel. When the printer is on line, press the LOAD/EJECT button once to select the 8.5-inch page length. The printer beeps four times to signal that the 8.5inch length has been selected. If you press the LOAD/EJECT button again, the printer beeps three times and returns to the page length selected by DIP switch 2-1.

Skip Over Perforation

By changing the setting of DIP switch 2-3, you can set skip over perforation to on or off. If this feature is on when using continuous paper, a one-inch margin is provided between the last printable line on one page and the first printable line on the next page. This feature is very convenient if your application program does not provide for top and bottom margins.

If you adjust your loading position correctly, you can get half of the margin at the bottom of one page and half at the top of the next page, as shown in the following illustration.

Using the Printer 3-11

Adjusting the Loading Position

The Loading Position The loading position is the position of the paper when it has been loaded automatically by the printer.

This position is important because it determines where the printing begins on the page. If the printing is too high or too low on the page, change the loading position using the micro-adjustment feature described in the next section.

CAUTION: Never use the platen knob to feed paper except in case of a paper jam or other paper feeding problem. (If you need to use the platen knob, make sure the power is off.) If you need to adjust the loading position, always use the micro-adjustment feature.

Until the loading position is reset, the printer remembers this position even if it is turned off, and uses it as a reference point for feeding paper.

The micro-adjustment feature moves the paper in 1/180-inch increments to make fine adjustments to the loading position. Once you have used micro-adjustment to change the loading position of continuous paper, the printer remembers that position even after it is turned off.

When you use micro-adjustment to change the loading position of single-sheet paper, however, the printer does not remember this position after the power is turned off. When the power is turned back on, the loading position returns to its factory setting.

3-12 Using the Printer

Adjusting the Loading Position

Using Micro-adjustment 1. Make sure that the printer is turned on and that either a single sheet

or continuous paper is ready to be loaded.

2. Press the LOAD/EJECT button to feed paper to the loading position. Then press the ON LINE button; the MULTI-PART light begins to blink.

I:::: MULTI - PART

Note: You can use the FORM FEED and LINE FEED buttons for micro-adjustment only while the MULTI-PART light is blinking.

Using the Printer 3-13

Adjusting the Loading Position

3. Press the FORM FEED button to feed the paper forward or the LINE FEED button to feed the paper backward.

Note: When the paper reaches the factory-set loading position, the printer beeps and micro-adjustment feeding pauses for a moment before continuing. You can use this factory setting as a reference point when adjusting the printers loading position. When the paper reaches either the minimum or maximum top margin, the printer beeps and the paper stops moving.

3-14 Using the Printer

Using Short Tear-Off

When you are finished printing, the short tear-off feature automatically feeds the perforation of the continuous paper to the tear-off edge of the printer cover so that you can tear off the last sheet. When you resume printing, the paper feeds backward to the loading position. This feature lets you save the paper normally lost between documents.

To use this feature, set DIP switch 2-2 to on, and make sure that the length of the continuous paper matches the length set by DIP switch 2-1. Then load continuous paper in the normal way.

0-t CAUTION: To change the setting of a DIP switch, first turn .

off the printer, change the DIP switch setting, and then turn the printer back on.

You can leave the short tear-off feature turned on (DIP switch 2-2 on) even when you are using single sheets. When you move the paper release lever to the single-sheet position, the short tear-off feature is disabled.

WARNING: Never use short tear-off with labels. Otherwise, labels may come off their backing and jam the printer.

When you have finished printing, if the perforation is at the top of form position, the printer automatically feeds the perforation of the continuous paper to the tear-off edge of the printer cover. You can then tear off the page using the tear-off edge as shown on the next page.

Using the Printer 3-15

Using Short Tear-Of

If the page perforation is not properly aligned with the tear-off edge, you can adjust the tear-off position using micro-adjustment, as described below.

Note: Short tear-off is not performed unless printing of a page is completed and the paper has advanced to the top of the next page.

When you resume printing after tearing off the sheet, the paper automatically feeds backward to the loading position before printing begins.

Adjusting the Tear-off Position If the papers perforation does not meet the tear-off edge, you can adjust the tear-off position using the micro-adjustment feature.

3-16 Using the Printer

Using Short Tear-Off

1. Make sure the printer feeds the paper to the tear-off position after printing the document.

2. The MULTI-PART light should begin blinking, indicating that you can now use the micro-adjustment feature to make fine adjustments to the tear-off position.

Using the Printer 3 - 1 7

Using Short Tear-Off

3. To make fine adjustments to the tear-off position, press the FORM FEED button to feed the paper forward or the LINE FEED button to feed it backward.

You can now tear off your document from the perforation and resume printing. The printer remembers this new tear-off position even after the printer is turned off and on again.

3-18 Using the Printer

Selecting Typestyles

You can produce a wide range of typestyles by selecting different character fonts, widths, and other enhancements from the SelecType control panel or by using software commands. This section describes only the features controlled by SelecType. To use software commands, see the Command Summary in Chapter 9.

You can use the SelecType section of the control panel to choose fonts and condensed printing. Orange lights indicate which features you have chosen. For example, if both indicator lights are lit, the slot is selected for your optional font cartridge (if one is installed).

Selecting Typestyles

Note: The settings you select using the SelecType panel remain valid until the printer is turned off or until it receives other instructions from software. Some application programs, however, are designed to control all typestyle functions, These programs cancel all previous typestyle settings by sending certain software commands before printing. Because these commands override SelecType settings, you should use the programs print options instead of SelecType to select your typestyles. If SelecType does not work with a particular application, check your software manual for instructions on selecting typestyles.

Character Fonts Your printer has three built-in fonts:

ROMAN

'"#$%&'()*t,-./0123456789:;<=>?BABCDEFGHIJK LMNOPQRSTUVWXYZ'F^-'abcdefghijklmnopqrstuv

SANS SERIF

3-20 Using the Printer

Selecting Typestyles

The DRAFT mode uses fewer dots per character for high-speed printing, which makes it ideal for rough drafts and editing work.

ROMAN and SANS SERIF are Letter Quality (LQ) fonts. Letter Quality takes a little longer to print, but produces nicely formed characters suitable for most documentation requirements.

Other fonts are available on optional font cartridges. See Multi-Font Module in Chapter 5.

Condensed Mode You can use the condensed mode to change the size of printed characters. In the condensed mode, characters are approximately 60 percent of the width of normal characters. Hence, condensed printing is very useful for spreadsheets and other applications where you need to print the maximum amount of information on a page. You can combine the condensed mode with 10 and 12 cpi printing, but not 15 cpi.

To select the condensed mode, simply press the CONDENSED button so that the orange indicator light comes on. To turn off the condensed mode, press the button again.

The following printout compares normal 10 and 12 cpi with condensed 10 and 12 cpi. The condensed 10 cpi is 17 cpi, and the condensed 12 cpi is 20 cpi.

This is 10 CPI printing. This is condensed 10 CPI printing, This is 12 CPI printing. This is condensed 12 CPI printing.

Selecting an International Character Set

International character sets provide you with the characters and symbols used in other languages. You can select one of eight international character sets by changing the DIP switch settings.

Whenever the printer is turned on, reset, or initialized, the character set selected by the DIP switches becomes the default character set.

To select an international character set, set DIP switches 1-1, 1-2, and 1-3 according to the table below.

Choosing a Character Table

DIP switch 1-7 selects either the italic character table or the Epson Extended Graphics character table. The Epson Extended Graphics character table contains international accented characters, Greek characters, mathematic symbols, and character graphics for printing lines, corners, and shaded areas.

If you have an IBM or IBM-compatible computer, select the Epson Extended Graphics table when you wish to print character graphics as they are displayed on the screen. Even if you select Epson Character Graphics, you can still print ordinary text and italics. For italics, see the description of the ESC 4 command in the Command Summary, Chapter 9.

Note: In most cases, Epson Extended Graphics is the preferred selection.

Sample printouts of the italic characters and the Epson Extended Graphics characters are shown below.

Software and Graphics 4-1

Enhancing Your Printing

You can obtain a wide variety of printing effects with your printer, from changing the number of characters per inch to using special effects on selected words and phrases. This section gives you a sampling of the features you may select with your software.

For software control of these features, see the instructions for your application programs or look up their specific commands in the Command Summary in Chapter 9.

Character Spacing To add greater variety to your documents, your printer has three cpi spacings, as well as proportional spacing. Each one can be selected with a software command.

For each of the three built-in fonts, you can choose a character spacing of 10, 12, or 15 characters per inch, or proportional spacing. The printout below compares the three cpi spacings:

This is 10 cpi printing. This is 12 cpi printing. This is 15 cpi printing.

As shown above, 15 cpi characters are only about two-thirds the height of 10 and 12 cpi characters. This makes 15 cpi particularly useful when you want to separate certain material from the main text.

In fixed cpi spacing each character is given the same amount of space. The width of proportional characters, however, varies from character to character. For example, a narrow letter like i takes less space than a wide letter like W. The width of each proportional character is given in the Appendix.

4-2 Software and Graphics

Enhancing Your Printing

The following printout compares 10 cpi spacing with proportional spacing:

This is 10 cpi printing. This is proportional printing.

rNote: Proportional spacing is not available in the draft mode. I

Character Size In addition to the basic cpi spacings and proportional spacing, your printer offers three other modes that can change the size of your printing. These modes are double-wide, double-high, and condensed.

The double-wide mode doubles the width of any size character, while the double-high mode doubles the height of any size character. These modes are useful for emphasizing document titles and headings in reports, but are usually not suitable for large amounts of text. These modes can also be combined to obtain even more impressive printing results.

Software and Graphics 4-3

Enhancing Your Printing

Both 10 and 12 cpi printing can be reduced to about 60 percent of their normal width using the condensed mode. This mode is particularly useful for printing wide spreadsheets because condensed 12 cpi printing allows you to print up to 272 characters on a 13.6-inch line.

The condensed mode can be selected with a software command, or by using SelecType (see Chapter 3). Even if you turn the condensed mode on with SelecType, you can still turn it off with a software command.

Condensed 10 cpi gives you many characters on a line,

Condensed 12 cpi gives you even lore characters on a line,

Widening or narrowing the characters also widens or narrows the spaces between words. Because word processors usually create a left margin by printing spaces, you may need to change the left margin and the number of characters on a line to keep the margins correct if you change character widths.

Special Effects and Emphasis The printer offers two ways of emphasizing text and also allows you to use underlining, superscripts, subscripts, and italics. These features can be controlled directly by software commands. Many application programs can also produce some of these effects. See your application program manual for details.

Emphasized and double-strike printing Emphasized and double-strike printing can give words and phrases added prominence. In emphasized mode, each character is printed twice as the print head moves across the paper, with the dots in the second pass printed slightly to the right of the first pass. This process produces darker, more fully formed characters.

4-4 Software and Graphics

Enhancing Your Printing

In double-strike mode, the print head prints each line twice, making the text bolder. For even greater boldness, emphasized and double- strike can be combined. The following samples show the different effects you can achieve using these modes alone and in combination.

Underlining, strike-through, and overlining The underline, strike-through, and overline modes are useful for highlighting selected text. This feature can be used to score spaces, subscripts, and superscripts without a break. You can choose from a variety of line styles, including single, double, broken, or continuous. See the ESC ( - command in Chapter 9 for more information.

Outline and shadow The outline and shadow features are useful for adding variation and emphasis to text that you wish to stand out, such as headings. The following samples show the outline and shadow features individually, plus a combination of outline with shadow.

Selecting Typestyles With Master Select Your printer has a special ESCape code called Master Select that allows you to choose many combinations of these nine modes: 10 cpi, 12 cpi, proportional spacing, condensed, emphasized, double-strike, double-wide, italics, and underline. For more information on sending ESCape codes to your printer, see Chapter 9.

The format of the Master Select code is shown below:

ASCII: ESC ! n Decimal: 27 33 n Hexadecimal: 1B 21 n

4-6 Software and Graphics

Enhancing Your Printing

The variable n is a number that identifies the mode or combination of modes. To find the value of n, use the following table to add up either the decimal or hexadecimal numbers for the features you want.

For example, to print a title you may want to use double-wide 12 cpi characters printed in the double-strike mode. You would add three numbers together to calculate the value of n.

12 cpi 1 D o u b l e - s t r i k e 1 6 D o u b l e - w i d e 3 2

n = 49

After calculating the value of n, you use the Master Select command to send the value to the printer.

ASCII: ESC ! 1 Decimal: 27 33 49 Hexadecimal: 1B 21 31

Software and Graphics 4-7

Enhancing Your Printing

The print quality and font must be set separately, using SelecType or the ESC x and ESC k commands. There are two more things to consider when using the Master Select command:

l Master Select cancels any of the other listed features that you do not set. For example, if you have already set a different character width and you use Master Select to set emphasized double-strike, the character width is reset to 10 cpi.

l Proportional spacing overrides 10, 12, and 15 cpi.

4-8 Software and Graphics

Graphics

The dot graphics mode allows your printer to produce pictures, graphs, charts, or almost any other pictorial image you can create.

Because many commercial software programs use graphics, you may be able to print pictures and graphs like the ones on this page and the next by simply giving your software a few instructions.

The quickest and easiest way to print graphics on your printer is to use a commercial graphics program. With such programs you usually create an image on your monitor then give a command to send the image to the printer.

If you use commercial software that produces graphics, all you need to know about dot graphics is how to use the software. The application program will take care of the printer. (Some programs call this bit image printing.) On the other hand, if you wish to do your own programming or merely wish to understand how this printer prints graphics, read on.

The Print Head To understand dot graphics you need to know a little about how your printers print head works.

The print head has 24 pins. As the print head moves across the page, electrical impulses cause the pins to fire. Each time a pin fires, it strikes the inked ribbon and presses it against the paper producing a small dot. As the print head moves along, the pins fire time after time in different patterns forming letters, numbers, and symbols.

Because the dots overlap each other both horizontally and vertically in Letter Quality mode, it is difficult to see the individual dots. Instead, the letters and symbols seem to be made up of unbroken lines.

In order for the dots to overlap vertically, the pins in the print head are in more than one column, but the intelligence of the printer handles the timing of pin firings so that the effect is that of 24 pins arranged in a single vertical column.

Dot patterns The print head is able to print graphics as well as text because graphic images are formed by the printer in about the same way that pictures in newspapers and magazines are printed. If you look closely at a

4-10 Software and Graphics

Graphics

newspaper photograph, you will find that it is made up of thousands of small dots. Your printer also forms its images with patterns of dots, as many as 360 dots per inch horizontally and 360 dots per inch vertically. The images printed by this printer can, therefore, be as finely detailed as the ones at the beginning of this section.

Twenty-four-pin graphics The graphics mode that takes full advantage of this printers print head is 24-pin graphics. This mode has five densities, but for simplicity this explanation deals with only one of them, triple-density.

Triple-density prints up to 180 dots per inch horizontally. As the print head moves across the paper, every 1/180th of an inch it must receive instructions about which of its 24 pins to fire. At each position it can fire any number of pins, from none to 24. This means that the printer must receive 24 bits of information for each column it prints. Since the printer uses S-bit bytes of information in communicating with the computer, it needs three bytes of information for each position.

Pin labels To tell the printer which pins to fire in each column, you first divide each of the vertical columns into three sections of eight pins each and consider each section separately. Since there are 256 possible combinations of the eight pins in each section, you need a numbering system that allows you to use a single number to specify which of the 256 possible patterns you want. This numbering system is shown below :

Software and Graphics 4-11

To fire any one pin, you send its number to the printer. To fire more than one pin at the same time, add up the numbers of the pins and send the total. Using these labels for the pins, you fire the top pin by sending 128. To fire the bottom pin, you send 1. If you want to fire only the top and bottom pins, you simply add 128 and 1, and send 129.

By adding the appropriate label numbers together, you can fire any combination of pins. Below are three examples of how to calculate the number that will fire a particular pattern of pins.

128 1

3 2

8

2 - 1 7 0

With this numbering system, any combination of the eight pins adds up to a decimal number between 0 and 255, and no numbers are duplicated.

Since there are 24 pins in each column, you must make a calculation for each of the three sections in each column. As you can see, this method of planning and printing dot graphics requires considerable calculation. Because triple-density uses 180 columns per inch, printing a single line of triple-density graphics only one inch long requires 540 numbers. Fortunately, commercial graphics software is available to do these calculations for you.

Before you can put these numbers into a graphics program, however, you need to know the format of the graphics command.

Graphics

The Graphics Command The graphics mode command is quite different from the other commands used by the printer. For most of the other printer modes, such as emphasized and double-wide, one ESC code turns the mode on and another turns it off. For graphics, the command is more complicated because the code that turns on a graphics mode also specifies how many columns it will use. After the printer receives this code, it interprets the numbers that follow as pin patterns and prints them on the paper.

Your printer has one command that allows you to use any of the 11

graphics options. The format of the command is:

ESC * m n1 n2 data

In this command, m selects the graphics option and n1 and n2 specify the number of columns to reserve for graphics. The available graphics options are listed below:

* Adjacent dots cannot be printed in this mode.

Software and Graphics 4-13

Graphics

Column Reservation Numbers The graphics command requires more than one number to specify how many columns to reserve because one line can use thousands of columns, but the printer does not use numbers larger than 255 in decimal. Therefore the graphics mode command uses two numbers, n1 and n2, for reserving columns.

To find n1 and n2, divide the total number of columns by 256. The result is n2; the remainder is n1. Since the command is set up for two numbers, you must supply two even if you need only one. When you need fewer than 256 columns, just make n1 the number of columns you are reserving and make n2 a zero.

For example, if you wish to send 1632 columns of graphics data, n1 should be 96 and n2 should be 6 because 1632 = 96 + (6 x 256).

The printer interprets the number of bytes specified by n1 and n2 as graphics data, no matter what codes they are. This means that you must be sure to supply enough bytes of graphics data or the printer will stop and wait for more data and will seem to be locked. If, on the other hand, you supply too much graphics data, the excess will be interpreted and printed as regular text.

A Simple Graphics Program This first program is just a simple example to show you how the graphics command, column reservation numbers, and data can be used in a BASIC program.

Type in and run the following program. Be especially careful to include both semicolons. The program produces the printout you see below:

10 WIDTH "LPT1:",255 20 LPRINT CHR$(27)"*"CHR$(32)CHR$(40)CHR$(0); 30 FOR X=1 TO 120 40 LPRINT CHR$(170); 50 NEXT X

Line 20 selects single-density 24-pin graphics mode (mode 32) and also reserves 40 columns for graphics. Since 24-pin graphics requires three bytes of data for each column, line 30 begins a loop to supply 120 bytes of data. Line 40 contains the number 170, which produces the first pin pattern shown in the section on pin labels, and line 50 ends the loop.

Designing Your Own Graphics With what you know now, you can use the simplest application of graphics-calculating by hand the data to print the graphic image. While this method is the most tedious, it helps you understand dot graphics. It is also useful for small graphic elements that are used many times.

Software and Graphics 4-15

The illustration below shows how you can use a grid on paper to plan where you want dots to be printed. This grid is for a single line of graphics 42 columns long. Since each line of 24-pin graphics is approximately 1/8th of an inch high and since triple-density graphics prints 180 dots per inch horizontally, a design planned on this grid will be about 1/8th of an inch high and less than 1/8th of an inch wide.

! / I

The actual pattern that the printer prints on the paper is, of course, made up of dots that overlap each other both vertically and horizontally. The reason the planning grid uses an x for each dot is that using an accurate representation of the dots makes calculating the data numbers difficult because they cover each other. Therefore, remember that each x represents the center of a dot, and the dots actually overlap.

Write the assigned values of the pins next to your design, then total the values for each column of dots. These totals are the values that you send to the printer as graphics data to print the design.

Below is the same grid divided into three sections to make the data calculation easier. At the bottom of each section of each column is the total of the pin numbers for that section. This gives you the total of 126

Below is the BASIC program that prints the design shown on the previous pages. Note that the data numbers in lines 80 through 140 are the same numbers that are at the bottom of each section in the last illustration.

In this program, line 20 assigns the graphics option (24-pin triple-density) with code 39. Code 42 sets the number of pin columns at 42. Lines 80 through 140 contain 126 bytes of data (42-pin columns x 3 bytes) for each pin column. Lines 30 through 60 print the design that you see below:

Notice that the dots overlap quite a bit. This design was printed using the triple-density, 24-pin graphics option because the density is the same (180 dots per inch) in both directions (horizontal and vertical).

User-defined Characters

With this printer, it is possible to define and print characters of your own design. You can design an entirely new alphabet or typeface, create special characters for use as mathematical or scientific symbols, or create graphic patterns with user-defined characters to serve as building blocks for larger designs.

Below, you can see samples of typefaces created with the user-defined character function.

Note: To use user-defined characters, you must turn DIP switch 2-5 O f f .

You can make the task of defining characters easier by using a commercial software program that assists you in creating characters or simply supplies you with sets of characters already created. Also, some popular software programs make use of the printers user-defined character function to enhance printouts. (These characters are called download characters in some programs.)

The standard ASCII characters are stored in the printers Read Only Memory (ROM) or optional Multi-Font Module, and the user-defined characters are stored in the printers Random Access Memory (RAM).

Designing Your Characters User-defined characters are like dot graphics because you send the printer precise instructions on where you want each dot printed. In fact, planning a user-defined character is like planning a small dot graphics pattern.

4-20 Software and Graphics

User-defined Characters

Design grids To design a character you use a grid that is 24 dots high-one dot for each pin on the printers print head. The width of the character matrix depends on the character set in use. For draft characters, the grid is nine dots wide, for Letter Quality it is 29 dots wide, and for proportional characters it is 37 dots wide. The dots for both Letter Quality and proportional characters are spaced more closely together than those for draft characters.

The illustrations below show the two design grids. The line at the side, labeled cap, indicates the top of a standard capital letter. The line labeled base indicates the baseline for all letters except those with descenders (the bottom parts of such letters as j and y). The bottom row is usually left blank because it is needed for underlining.

The grid on the right side can be used for either Letter Quality or proportional characters. For Letter Quality you do not use all the columns.

Draft pica Letter quality / Proportional

Software and Graphics 4-21

User-defined Characters

There is one restriction in designing characters. Dots in the same row may not print in adjacent columns. This means that there must be an empty dot position both to the left and right of each dot that prints. This is true in draft, Letter Quality, and proportional mode.

Defining Your Characters The first step in defining characters is to place the dots on a grid just as you want them to print. The examples shown here, like the ones in the graphics section, use an x to represent each dot.

In the illustration below, you see a draft grid with a simple user- defined character planned on it.

Now you translate the dot pattern youve created on paper to a numeric format so you can send the data to your printer. Every dot has an assigned value. Each vertical column (which has a maximum of 24 dots) is first divided into three groups of eight dots. Each group of eight dots is represented by one byte, which consists of eight bits. Hence, one bit represents one dot.

4-22 Software and Graphics

User-defined Characters

Data numbers The bits within each byte have values of 1, 2, 4, 8, 16, 32, 64, and 128. In the vertical column of dots, the bits are arranged so that the most significant bit (with a value of 128) is at the top of the column and the least significant bit (with a value of 1) is at the bottom.

The next illustration shows how to use this method to calculate the data numbers for the character in this example. On the left side of the figure, the data numbers are calculated for the middle column. The value of each byte is calculated by adding the values of the rows in which dots appear. The right side of the figure shows the whole character with the three data numbers for each column indicated at the bottom.

This manual uses decimal numbers because the program examples are written in BASIC and everyone is familiar with decimals. The data you send to your printer, however, must be in the form (binary, decimal, or hexadecimal) that you can use with your programming language.

Software and Graphics 4-23

User-defined Characters

You have seen how to design a character by placing dots on a grid and translating the dots to decimal equivalents. The last step in defining a character is sending this information to your printer.

Sending Information to Your Printer The printer loads characters in the print style (Letter Quality, draft, or proportional) that the printer is currently using. It also records whether italic, superscript, or subscript is turned on. This means that if you want to print a character in italics, for example, you must have the italic mode turned on when you define the character.

The command your printer uses to define characters is one of the most complex in its repertoire. The format of the command is this:

ESC & 0 n1 n2 d0 d1 d2 data

The ESC & is simple enough. The 0 (which is ASCII code 0, not the character zero in quotation marks) allows for future enhancements. At this time, it is always ASCII 0.

You can define many characters with a single command. The values n1 and n2 are the ASCII codes of the first and last characters you are defining. If you are defining only one character, n1 and n2 are the same. You can use any codes between decimal 32 and 127 for n1 and n2, but it is best not to define decimal 32, which is the code for a space. Also, you can use letters in quotation marks instead of ASCII codes for n1 and n2.

Note: Because user-defined characters require additional memory, you must set DIP switch 2-5 to 1 KB (off) before downloading these characters.

4-24 Software and Graphics

User-defined Characters

An example will show how to specify n1 and n2. For instance, if you wanted to redefine the characters A through Z, n1 would be A (or ASCII code 65) and n2 would be Z (or ASCII code 90). So the command ESC & 0 AZ (followed by the appropriate data) would replace the entire alphabet of capital letters.

Following the specification of the range of characters to be defined in this command are three data bytes, d0, d1, and d2, that specify the width of the character and the space around it. The left space (in dot columns) is specified by d0, and the right space is specified by d2. The second byte, d1, specifies the number of columns of dots that are printed to make up the character. By varying the width of the character and the spaces around it, you can create proportional-width characters that print at draft speed. The table below shows the maximum values for these bytes.

Mode d1 d0 + d1 + d2

Draft 9 12

Letter Quality 10 cpi 29 36

Letter Quality 12 cpi 23 30

Proportional 37 42

The last part of the command to define your characters is the actual data that defines the dot patterns for each character. Since it takes three bytes to specify all the dots in one vertical column, your printer expects d1 x 3 bytes of data to follow d2.

Software and Graphics 4-25

User-defined Characters

This example of a character definition program should make this clear:

10 LPRINT CHR$(27)"x0" 20 LPRINT CHR$(27)"&"CHR$(0); 30 LPRINT "@@"; 40 LPRINT CHR$(1)CHR$(9)CHR$(1); 50 FOR I=1 TO 27 60 READ A: LPRINT CHR$(A); 70 NEXT I 80 LPRINT "@@@@@" 90 LPRINT CHR$(27)"%"CHR$(1); 100 LPHINT "@@@@@" 110 LPRINT CHR$(27)"%"CHR$(0); 120 LPRINT "@@@@@" 130 END 140 DATA 1,0,0,2,0,0,4,0,0 150 DATA 8,0,0,23,255,240,8,0,0 160 DATA 4,0,0,2,0,0,1,0,0

In line 10, the ESC x0 command selects draft printing.

The actual character definition starts in line 20. The two @ signs in line 30 represent n1 and n2, the range of characters being defined (in this case, a range of 1). Line 40 contains d0, d1, and d2.

The information about the actual character design (which is contained in the DATA statements at the end of the program) is sent to the printer in the loop between lines 50 and 70.

Note: When defining Letter Quality or proportional characters, put a WIDTH statement in your program to prevent carriage return and line feed codes from interfering with your definitions.

4-26 Software and Graphics

User-defined Characters

Printing User-defined Characters If you entered the previous program example, you defined an arrow and placed it in the RAM location for ASCII code 64 (replacing the @ sign). You can now print out a three-line sample of your work. The first and third lines (printed by lines 80 and 120) print the normal @ sign. The second line (printed by line 100) prints out the arrow that you defined.

Run the program to see the printout below:

As you can see, both sets of characters (the @ from the original characters in ROM that the printer normally uses and the alternative character you defined) remain in the printer available for your use. The command to switch between the two sets is used in line 90 and 110. It is:

ESC % n

If n is equal to 0, the normal ROM character set is selected (this is the default). If n is equal to 1, the user-defined character set is selected. If you select the user-defined character set before you have defined any characters, the command is ignored and the ROM characters remain in use.

You may switch between character sets at any time-even in the middle of a line. To try this, place semicolons at the end of lines 80 and 100 in the program example.

Software and Graphics 4-27

User-defined Characters

Copying ROM Characters to RAM After running the program, if you select the user-defined character set and try to print other characters, the only one that will print is your arrow. Since no other characters are in the printers user-defined RAM, there is nothing else to print. Other characters sent to the printer do not even print as spaces; its as if they were not sent at all.

In many cases, you will want to redefine only a few of the characters to suit your needs-the rest of the alphabet will work fine as it is. As you have seen, it is possible to switch back and forth, at will, between the normal character set and your user-defined character set. It is, however, rather inconvenient.

Therefore, your printer has a command that allows you to copy all of the standard characters from ROM to the user-defined character set.

The command format is as follows, where the value of n represents the font family:

E S C : 0 n 0

Note: This command cancels any user-defined characters you have already created. You must send this command to the printer before you define characters.

If you use this command at the beginning of a program, then define your special characters and select the user-defined set, you can print with the user-defined set as your normal character set. You never need to switch back and forth between sets.

4-28 Software and Graphics

User-defined Characters

Letter Quality Characters If you select Letter Quality printing with the ESC xl command, you can design user-defined characters using up to 29 columns of the Letter Quality/Proportional grid. The dot columns are spaced closer together horizontally than draft dot columns (the horizontal dot spacing is 1/360th of an inch as opposed to 1/120th of an inch for draft characters).

Proportional mode characters Selecting the proportional character mode yields user-defined characters of the highest resolution. Characters can be designed using all 37 columns of the Letter Quality/Proportional grid.

Remember that in Letter Quality and proportional modes, as in draft mode, you cannot place dots in adjacent columns. There must be an empty dot position both to the left and right of each dot that prints.

Superscripts and Subscripts You can also create superscript and subscript user-defined characters. Just as Letter Quality characters are defined when the Letter Quality mode is selected, superscript and subscript characters are created when either superscript or subscript is selected.

These characters can be used as either superscripts or subscripts. The characters are exactly the same; only their placement is different. The difference between these characters and regular characters is that superscript and subscript characters are smaller. They are a maximum of 16 dots high. Their maximum width in dot columns is shown in the table below:

Mode d1

Draft 7

Letter Quality 23

Proportional 23

d0 + d1 + d2

Software and Graphics 4-29

User-defined Characters

Since superscript and subscript characters are smaller, when you define them you only need two bytes of data for each vertical row of dots. Design grids for these characters are shown in the figure below:

Draft pica Letter Quality

and Proportional

Mixing Print Styles Each of the three user-defined character modes (draft, Letter Quality, and proportional) can be used in combination with most of your printers various print styles. For instance, emphasized mode works with user-defined characters. The characters you design are enhanced to give this printing effect.

Mixing the three types of user-defined character sets is not possible. For example, if you select draft and define some characters, then select proportional and define some more, the first draft character definitions are deleted. Only one type of character definition may be stored in RAM at any time.

4-30 Software and Graphics

User-defined Characters

If you define characters in one mode, then switch to another mode and select the user-defined character set, the command is ignored and nothing is printed. The user-defined character definitions, however, remain unaffected. If you switch back to the mode in which they were defined, you can then select and print them.

Keep in mind that user-defined characters are stored in RAM, which is not permanent memory. When the printer power is turned off or the printer is initialized with the INIT signal, the user-defined characters are lost. (Some computers do this each time BASIC is loaded.)

The Interface Boards

A number of optional interfaces are available in case your computer is either not provided with a parallel interface or you wish to increase the memory capacity of your printers buffer.

Choosing an Interface Optional interfaces can be divided into three main categories which are described briefly below.

IEEE-488 interfaces offer standardized connections, trouble-free operation, and the ability to connect computers, printers, and other devices on the same line so that they may share data freely.

The buffered parallel interfaces also offer trouble-free operation and standardized connections. They provide the printer with more memory to free the computer for other tasks when printing large amounts of text or graphics. You can increase the printers data buffering capacity by an additional 32 KB (about 10 pages).

Serial interfaces are required if your computer is not equipped with a parallel interface or if you need an interface that conforms to the Current Loop standard instead of RS-232C. These interfaces also provide some combination of the following features: X-ON/X-OFF data communication protocol, loopback self test modes, and data buffers that increase the printers data buffering capacity.

5-40 Using the Printer Options

The Interface Boards

Compatible Interfaces The following is a list of Epson interfaces that are compatible with your printer.

Interface number Name

#8143 New Serial Interface

#8148 Intelligent serial interface

#8165 Intelligent IEEE-488 interface

#8172 32 KB buffered parallel interface

All Epson interfaces have the Epson name printed on them. If the board has an identification code printed on it, it is a four-digit number beginning with 8 and should correspond to one of the numbers listed in the table above.

Also, Coax and Twinax interfaces are available from third party vendors. These interfaces allow connectivity to mainframes and minicomputers and emulation of IBM printers. The Coax (EP-Connect) is available from Avatar Corporation (508) 435-6872, and the Twinax (I-O8300) is available from I-O Corporation (801) 973-6767.

Installation 1. Turn off your printer. Then unplug the printer and disconnect the

interface cable.

CAUTION: When an optional interface board is installed, be sure to disconnect the printer cable from the printers built-in

#8143 New Serial Interface If you are using an optional interface, it may be necessary for you to alter the communication protocol of the printer or the computer so that they can communicate properly. In most cases, you should use the information in your optional interface manual or your computers manual to match the computer with the interface.

If you are using the #8143 optional interface board, make sure that you read through the section below on baud rate selection. You may also want to see the following sections on handshaking timing and error handling for interface information specific to your printer.

For all other data transfer conventions, such as word structure or communications protocol, use the information in the manual supplied with your #8143 optional interface.

Using the Printer Options 5-49

The Interface Boards

Baud rate selection You can select baud rates from 75 to 19,200 BPS (Bits Per Second). When setting the baud rate, make sure you use the bit rate selection table for printers with buffers (in the #8143 interface manual).

For more information on the printers input buffer settings, see the section on DIP switch functions in Chapter 3 of this manual.

Handshaking timing When the vacant area for data in the input buffer drops to 256 bytes, the printer outputs an X-OFF code or sets the DTR flag to "1" (MARK) indicating that it cannot receive data.

Error handling When a parity error is detected, your printer prints an asterisk (*). All other errors, including framing and overrun, are ignored.

7-10 Troubleshooting

Printing

Problem Solution

The print position is not what you expected.

Printing starts too high or too low on the

page.

One line of printing has taken up two lines.

Line spacing is incorrect.

The loading position may be incorrect. Use micro-adjustment to adjust the loading position. See Chapter 3. If the problem persists, check the top margin set by your application software and adjust it.

Auto line feed may be on. Turn off DIP switch 2-4.

The margin setting may not be correct. Use your application program to change the margin.

In BASIC, enter either of the following statements:

WIDTH LPRINT 255

GDTH LPT1 255

If the printer still does not print properly, set the right margin to the maximum setting using ESC Q. See Chapter 9.

Line spacing is too tight or too far apart. Use your application program to specify line spacing using ESC 0, ESC 2, ESC 3, or ESC A. See Chapter 9.

Troubleshooting 7-11

Printing

Problem Solution

The print position is not what you expected (continued).

Page length does not match the length of the paper.

Regular gaps occur in the printout.

Skip over perforation is set, but the perforation does not fall in the center of the skip.

Check the page length set by your application software and adjust it if necessary, or change the page length setting with DIP switch 2-1.

If you are using the cut sheet feeder, the self test function prints the number of printable lines that can fit on a single sheet. Use this feature to determine the correct page length setting. See Chapter 3.

One-inch skip over perforation may be set. Set DIP switch 2-3 to off, or use your application program to cancel skip over perforation. See Chapter 3.

The loading position of the paper may be too high or too low. Use the micro- adjustment feature to reset the loading position so that the perforation is centered within the skip area.

Your application program may be setting the top and bottom margins. If this is the case, turn off skip over perforation by setting DIP switch 2-3 to off.

The page length for continuous paper may be set incorrectly. Set DIP switch 2-1 to 11 or 12 inches. See Chapter 3.

7-12 Troubleshooting

Printing

Note: Use the data dump mode to check data being sent from the computer. In the data dump mode, data is printed in hexadecimal format and in ASCII characters. See Data Dump Mode in Chapter 3.

If the printer still does not print, try the self test described in Chapter 1. If the self test works properly, the printer is all right, and the problem probably lies in the computer, the software, or the cable. If the self test does not work, contact the store where you purchased your printer or call the Epson toll-free number (1-800-922-8911).

Troubleshooting 7-13

The following section guides you through problems in handling single sheets and continuous paper. If you are having problems using the optional cut sheet feeder or pull tractor, see the section on options later in this chapter.

Problem Solution

Single sheets do not feed properly.

7-14 Troubleshooting

Paper Handling

Problem Solution

Single sheets do not feed properly (continued).

The LOAD/EJECT button was pressed and the platen rotated, but paper was not fed.

When the LOAD/EJECT button is pressed, the paper jams.

The paper release lever may be set in the wrong position. Push paper release lever back to the single-sheet position. See Chapter 2.

The left and right edge guides may be too close together, preventing the paper from feeding smoothly. Adjust the position of the edge guides so that the paper can move up and down freely. See Chapter 2.

The paper may not be firmly inserted. When feeding thicker than normal paper, press down lightly on the paper while pressing the LOAD/EJECT button.

The cut sheet feeder mode may be turned on (DIP switch 1-8 is on). When the cut sheet feeder is not in use, DIP switch 1-8 should be off. See Chapter 3.

The edge guides may be too far apart. Adjust the edge guides to the width of the paper.

The dimensions of the paper may exceed the specified limitations. Use only paper sizes that are within the specified range. Multi-part forms cannot be used with this printers single-sheet feeding system. See Chapter 8.

Troubleshooting 7-15

Paper Handling

Problem Solution

Single sheets do not feed properly (continued).

When the LOAD/EJECT button is pressed, the paper feeds through and then out of the printer.

The paper feed is crooked.

The paper does not fully eject.

The paper may have been between the edge guides before the printer was turned on. When loading single sheets, be sure that paper is not in the paper guide before you turn the printer on.

The paper guide may not be attached, or it may not be in the correct position. When printing on single sheets, use the paper guide in its upright position.

The paper may be dog-eared. Use new paper.

You may be trying to eject the paper using the FORM FEED button. Always press the LOAD/EJECT button to eject the paper.

The page length setting may be wrong. If the page length is incorrectly set by your software, the paper may not fully eject. Check your software settings.

Troubleshooting 7-17

Paper Handling

Problem Solution

Continuous paper does not feed properly (continued).

The paper feed is crooked or the paper jams.

The paper supply may be obstructed by a cable or some other object. Make sure that the paper feeds smoothly into the printer. See Chapter 2.

Your supply of continuous paper may be too far from the printer. Position your paper supply within 3 feet (1 meter) of the printer. See Chapter 2.

The paper may be caught on the edge guides. When using continuous paper, make sure that the paper guide is lowered to the horizontal position and that the edge guides are positioned as far apart as possible. See Chapter 2.

The holes on the sides of the paper may not be aligned with each other. Reposition the paper on the tractor pins. See Chapter 2.

The sprocket units are incorrectly positioned for the paper width. Move the right sprocket unit to remove any slack across the width of the paper. See Chapter 2.

The position of your paper supply may be preventing it from feeding straight. See Chapter 2.

7-18 Troubleshooting

Paper Handling

Problem Solution

Continuous paper does not feed properly (continued).

The paper feed is crooked or the paper jams (continued).

Regular gaps occur in the printout.

Skip over perforation does not function.

The sprocket lock levers may be unlocked, or the sprocket covers may be open. Position the sprocket units to match the width of your paper. Then, lock them in place by pressing the sprocket lock levers away from you. See Chapter 2.

The paper guide may be in the upright position. When using continuous paper, make sure that the paper guide is in the lowered position so that it can act as a paper separator. See Chapter 2.

The paper thickness lever may be in the wrong position. For printing on ordinary paper, always set the lever to position 2.

The paper dimensions may exceed the specified limitations. Use only paper sizes that are within the specified range. Your printer can print on continuous multi-part forms consisting of 1 original and 1 or 2 copies. See Chapter 8.

Skip over perforation may be interfering with your application program settings. Set DIP switch 2-3 to off.

You may not have turned off the power after setting DIP switch 2-3 to on. To make new DIP switch settings effective, turn the power off, then on again.

Troubleshooting 7-19

Paper Handling

Problem

Continuous paper does not feed properly (continued).

Skip over perforation is set, but the perforation does not fall in the center of the skip.

The loading position of the paper shifts slightly while printing several pages.

After printing stops, the paper automatically feeds forward.

The short tear-off function is selected (DIP switch 2-2 is on), but it does not work.

Solution

The page length for one page of continuous paper may be set incorrectly. Change the setting of DIP switch 2-1.

The loading position of the paper may be too high or too low. Use the micro- adjustment to reset the loading position.

The paper you are trying to feed may be too heavy for the built-in push tractor. When highly accurate paper feed is necessary, such as when printing carbon copies, use the optional pull tractor.

The short tear-off function may be selected. When you resume printing, the paper feeds backward to its loading position. If you do not need this function, set DIP switch 2-2 to off. See Chapter 3.

You may not have turned off the power after setting the DIP switch. To make new DIP switch settings effective, turn the power off, then on again.

There may still be data in the print buffer. The short tear-off function works only if the data in the print buffer is completely printed and the next print position is at the top of the next page.

7-20 Troubleshooting

Problem

Continuous paper does not feed properly (continued).

The short tear-off function is selected (DIP switch 2-2 is on), but it does not work (continued).

The LOAD/EJECT button is pressed to eject the paper, the paper feed stops, and paper does not fully eject or it jams.

Switching between single sheets and continuous paper cannot be performed properly.

When the LOAD/EJECT button is pressed to load continuous paper, the platen does not rotate and the paper is not loaded.

Paper Handling

Solution

Your program may not be sending a form feed command to the printer. At the end of your program or the page, send a form feed (FF). If you are using BASIC, be sure to add a semicolon (;) after the FF code to prevent any additional codes from being sent to the printer.

You may have tried to back feed too many pages. Before ejecting the paper, always tear off the last printed page. See Chapter 3.

You may be trying to eject labels. Labels may jam when they are fed backward, so always use the FORM FEED button and feed labels forward to eject them.

Pull the paper release lever forward to the continuous paper position, set the paper, then press the LOAD/EJECT button.

Troubleshooting 7-21

Paper Handling

Problem Solution

Switching between single sheets and continuous paper cannot be performed properly (continued).

The paper release lever is correctly set for continuous paper, but when the LOAD/EJECT button is pressed, the platen rotates backward and the paper comes of the sprockets.

When the LOAD/EJECT button is pressed to load a single sheet from the sheet guide, the platen rotates in reverse, the single sheet does not load, and the continuous paper comes off the sprockets.

A single sheet may be in the paper guide, causing the continuous paper to back out and to come off the sprockets. When using continuous paper, always make sure to remove any single sheets remaining in the paper guide.

The paper release lever may not be in the proper position. Push the lever back to the single-sheet position.

7-22 Troubleshooting

Paper Handling

Problem Solution

Switching between single sheets and continuous paper cannot be performed properly (continued).

Even with the paper release lever set correctly to the single-sheet position, the single sheet and continuous paper feed together and jam.

The short tear-off function does not operate properly.

One page is completely printed, but the paper does not feed,

Printing ended in the middle of a page.

The continuous paper may not have fed backward far enough to reach the standby position before you changed the position of the paper release lever. Remove the jammed paper and try again. Also, check that the PAPER OUT light comes on before changing the position of the paper release lever to make sure that the continuous paper is completely ejected. When there is more than one page to feed backward to eject, you must press the LOAD/EJECT button at least two times.

DIP switch 2-2, short tear-off mode, may be set to off. Set DIP switch 2-2 to on to turn on the short tear-off mode.

One page of data may not have been sent to the printer. Finish the page by sending a form feed code (FF) to the printer or by sending enough line feed codes (LF) to advance the remainder of the page.

Command Summary 9-1

Using the Command Summary

This chapter lists and describes all the commands available on your printer.

The first part of this chapter lists all commands in numerical order and gives the number of the page where each is fully described. If you know which command you are looking for, consult the numerical list.

Note: The Quick Reference card at the end of the book also contains a list of the commands divided by topic, with page number references that direct you to full explanations of the commands.

The second part of this chapter lists and describes each command separately; the commands are divided into the following subjects:

Printer operation Print size and character width MSB control Print enhancement Data control Word processing Vertical motion Character sets Horizontal motion User-defined characters Overall printing style Graphics

Each command description has a format section and a comment section. The format section gives the ASCII, decimal, and hexadecimal values for the command. These three formats are equivalent, and it should be easy to pick the one most suited to your purpose. The comment section describes the effect of the command and gives any additional information necessary for using it.

Note: Some application programs use control key sequences. See the Control Key chart on page 9-4.

9-2 Command Summary

Using the Command Summary

The simplest type of command consists of a single character to be sent to the printer. For instance, to print in condensed mode, the code format is:

A S C I I c o d e : S I Decimal : 15 Hexadecimal: 0F

This code can be sent from a program by sending the code 15 directly.

More complex commands consist of two or more character codes. For example, to print in double-wide mode, the code format is the following:

ASCII code: ESC W n Decimal: 27 87 n Hexadecimal: 1B 57 n

In this case n can be either 1 (on) or 0 (off), to begin or end double-wide printing. You can use either of the following commands to turn on double-wide print from BASIC:

LPRTNT CHR$(27);CHR$(87);CHR$(1) LPRINT CHR$(27);"W";CHR$(1)

For the following commands that use only 0 or 1 for the variable, either the decimal or hexadecimal values 1 and 0 or the ASCII characters 1 and 0 can be used:

ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, and ESC %

For example, in BASIC you can turn on proportional spacing with either of these statements:

LPRINT CHR$(27);"p";CHR$(1) LPRINT CHR$(27);"p";"1"

Command Summary 9-3

Using the Command Summary

Control Key Chart Some application programs use control key codes for decimal values 0-27. The table below gives you the proper values. The Control Key column indicates that you press the control key at the same time you press the key for the letter or symbol in that column. For example, you press the control key and A at the same time to send the value 1.

Some application programs that use this system cannot use Control-@, and many programs use the control keys for other purposes.

Set Relative Print Position

ESC \ n1 n2 27 92 n1 n2 1B SC n1 n2

Determines the position (relative to the current position) at which printing of subsequent data will start. To find n1 and n2, first calculate the displacement required in dots. If the displacement is to the left, subtract it from 65536. Send the resulting number using this formula: total number of dots = n1 + (n2 x 256). The command is ignored if it would move the print position outside the current margins. A unit is 1/120th of an inch in draft, and 1/180th of an inch in Letter Quality or proportional modes.

HT Format:

ESC p n 27 112 n 1B 70 n

Turns proportional mode on and off. The following values can be used for n: 1: Turns mode on. 0: Turns mode off.

The width of proportional characters varies from character to character. Therefore, a narrow letter like i receives less space than a wide letter like W. Proportional character widths are given in the Appendix. This command overrides fixed cpi fonts. When proportional is cancelled, the previously selected font is used. Graphic characters are printed in fixed cpi only; proportional mode is recommended for use with Roman and Sans Serif fonts only.

Proportional Width Table

This table lists the widths of your printers proportional characters. The values given are in 360ths of an inch. (For example, a value of 36 is 36/360ths of an inch.) You may need to enter these widths into a special table for your word processing program so it can calculate the number of proportional characters that will fit on a line.

The characters with no code indicated are international characters or graphics. See the table in Chapter 3 for the relevant codes for the international characters. Also, see the descriptions of the ESC R and ESC t commands in Chapter 9 for information on how to use these characters.

The following width table shows each character, its ASCII code (hexadecimal), and its width. If there are two numbers in the width column, the second one is for the superscript/subscript version of the character.

Glossary

Note that these definitions apply specifically to printers. If a word is italicized, see that topic for more information.

application program A software program that helps you carry out a particular task, such as word processing or financial planning.

ASCII Acronym for the American Standard Code for Information Interchange. A standardized coding system for assigning numerical codes to letters and symbols.

auto line feed When this feature is enabled using a DIP switch or external control through the parallel connector, the printer will automatically feed the paper one line after receiving a CR code.

baud rate A measure of the speed of data transmission. Usually expressed in bits per second or bps.

bidirectional printing Printing in which the print head alternates printing a line left to right then the next line right to left, and so on. Because the head prints in both directions, the overall printing speed increases by eliminating wasted (non-printing) movement.

binary See number systems.

bit A binary digit (0 or 1), which is the smallest unit of information used by a printer or computer. See also number systems.

buffer See input buffer and memory.

G l o s s a r y 1

byte A unit of information consisting of eight bits.

carriage return (CR) The control code that returns the print position to the left margin. When issued together with a line feed, the print position moves to the left margin of the next line. In bidirectional printing, the print head may not physically move to the left margin.

character set A collection of letters, numbers, and symbols that provides you with the characters used in a particular language.

condensed Printing in which each character is approximately 60 percent of the width of standard characters. For example, condensed 10 characters per inch (cpi) has 17 characters per inch. Useful for fitting wide tables or spreadsheets onto the paper.

continuous paper Paper which has sprocket-feed holes on both long edges, is perforated between pages, and is supplied in a folded stack. Also called fanfold paper.

control code In addition to the codes for printable characters, the ASCII standard also includes 33 other codes which are called control codes. These control codes perform such functions as sounding the beeper and performing a carriage return or line feed.

cut sheet feeder (CSF) An optional, detachable device which automatically feeds single sheets of paper into the printer.

data dump Sometimes called hex dump. A troubleshooting feature. When the printer is in the data dump mode, each code that it receives is printed in hexadecimal notation.

2 Glossary

decimal See number systems.

default A value or setting that takes effect when the equipment is turned on, reset, or initialized.

DIP switches Small switches in a printer that control various printer functions and set the default status of the printer when it is turned on or initialized. DIP stands for Dual In-line Package.

dot graphics A graphic design formed by patterns of dots. Also called bit image graphics.

dot matrix A method of printing in which each letter or symbol is formed by a pattern (matrix) of individual dots.

double-high printing Printing in which each character is twice as tall as normal.

double-strike printing A way of producing bolder characters. Each character is printed twice; the second time, the dots are printed slightly below the original dots. Can only be used in draft mode.

double-wide printing A print width in which each character is twice as wide as normal characters. (The cpi is halved.)

draft mode One of two print qualities available on your printer. Draft uses fewer dots per character for high-speed printing. See also Letter Quality.

emphasized printing A way of producing darker characters. In a single pass of the print head, characters receive twice the number of dots.

G l o s s a r y 3

Epson Extended Graphics character table The Epson Extended Graphics character table contains international accented characters, Greek characters, and character graphics for printing lines, corners, and shaded areas.

ESC (escape) code A special control code used to begin most printer commands.

ESC/P Abbreviation for Epson Standard Code for Printers. The system of commands lets you perform software control of your printer from your computer. It is standard for all Epson printers and supported by most application software for personal computers.

font A font is a style of type designated by a family name.

form In printer terminology, a form normally refers to a page.

form feed Refers to both a control code and a panel button that advances the paper to the top of the next page.

hexadecimal (hex) See number systems.

initialize To establish the initial default status of the printer by turning the printer on or by sending an INIT signal or code.

input buffer The memory in the printer in which data sent from the computer is stored while waiting to be printed.

interface The means of connection between the computer and printer. See also parallel interface and serial interface.

italic A typestyle in which the characters slant. This sentence is italicized.

4 Glossary

Letter Quality One of two print qualities available on your printer. Letter Quality provides better readability and appearance at a reduced print speed. See also draft mode.

line feed Both a control code and a panel button that advances the paper one line space.

loading position The position to which the paper is automatically loaded. It can be adjusted by using the micro-adjustment feature.

memory The printer, like a computer, has a memory. When you print a file from a computer, the contents of the file are transferred quickly from the computers memory to the printers memory. The printer then prints information from its own memory at a much slower rate. This way of printing frees the computer to do other work while the printer is still working. The printer memory is sometimes called the buffer memory or input buffer.

micro-adjustment A feature that adjusts the paper loading and short tear-off positions by the smallest possible increments.

number systems Three number systems are commonly used with printers:

decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. (This is the most familiar system.)

hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. This is frequently used by programmers. Any decimal number between 0 and 255 can be expressed by a two- digit hex number.

G l o s s a r y 5

binary is base 2 and uses only the digits 0 and 1. All information in computer systems is handled in binary form represented by electrical signals that are on or off. A binary digit is often called a bit: any decimal number between 0 and 255 can be expressed by an eight-bit binary number.

on line When the printer is on line, it is able to communicate with the computer connected to it.

paper-out sensor A small switch behind the platen that sends a signal when it is not in contact with paper, informing the printer and remote computer that there is no paper loaded, and causing the PAPER OUT light to go on.

paper tension unit The part of the printer that fits above the platen to assure proper paper tension in the printing area.

parallel interface An interface that connects the computer and the printer. A parallel interface transmits data one character or code at a time. See also serial interface.

platen The black roller that provides the backing for the paper during printing.

print quality Your printer has two types of print quality; draft and Letter Quality. Draft is for high-speed, draft quality jobs; Letter Quality is used to produce more polished documents.

proportional printing Printing in which the character width varies from character to character. For example, a capital W receives much more space than a lowercase i. The result looks more like a typeset book than a typewritten draft.

6 Glossary

pull tractor unit An optional device that feeds continuous paper and multi-part forms through the printer.

push tractor A built-in device that feeds continuous paper through the printer.

RAM Acronym for Random Access Memory. The portion of the printers memory used as a buffer and as a place for storing user-defined characters. All data stored in RAM is lost when the printer is turned Off.

reset To return a printer to its defaults, either by a command, an INIT signal, code, or by turning the printer off and on.

self test A method of checking the operation of the printer. When the self test is run, the printer prints out its current DIP switch settings and the characters that are stored in its ROM (Read Only Memory).

serial interface A serial interface transmits data one bit at a time. See also parallel interface.

short tear-off A feature that automatically feeds the perforation of continuous paper to the tear-off position to be removed by the operator, and then draws the paper back to the loading position. These positions can be adjusted using the micro-adjustment feature. See also micro-adjustment and loading position.

10 cpi A character spacing of 10 characters per inch. This is often the standard or default pitch. Also referred to as pica.

tractor The part of the printer that moves continuous paper through the printer by its sprockets gripping the holes in continuous paper.

G l o s s a r y 7

12 cpi A character spacing in which each character is slightly narrower than normal, so that there are 12 characters per inch. Also referred to as elite.

unidirectional printing Printing in one direction only. Allows more precise vertical alignment than bidirectional printing. Often used for printing graphics.

user-defined characters Characters that are defined and stored in the printer by the user. Also known as download characters.
