Internet Printing allows you to automatically print any e-mails that are sent to a specific e-mail account on your network. This is especially useful for printing information when you are not connected to the network. You can print from anywhere that you can access e-mail.

The Mail Server IP Address is where you will enter the address of your mail server. (This value must be a fixed IP address.) The Account Name and Account Password must be entered next. Enter the password again in the Verify Password field. Then, enter the time interval for the PrintServer to check for e-mail to be printed, in hours and minutes in the Check Mail every: field. You may even specify an e-mail address to which mails that cannot be printed are routed; this is useful for both graphic-intensive e-mails and for troubleshooting purposes. Enter this e-mail address in the Redirect unprintable Mail to: field.

Under the Printer settings, enter the Printer Model in the box provided. You can find this in the Device Manager. Then choose the Printer Port from the drop down box.

Chapter 8: Internet Printing Protocol (IPP) IPP (Internet Printing Protocol) is a new standards-based system to allow remote printing from a PC to any accessible printer. Normally, the printer will be attached to a computer or other device that functions as an IPP Server. For client PCs, it is necessary to install a compatible IPP Client program. The Client must also know the IP Address or URL of the IPP Server.

The PrintServer contains the necessary firmware to act as an IPP Server. No additional configuration is necessary. However, the following requirements must be met:

The PrintServer must have a valid IP Address. For printing via the Internet, the PrintServers IP Address must be external (allocated by your ISP), rather than an IP Address on your local LAN.

Any Router, Gateway, or Firewall linking your LAN to the Internet must NOT block the IPP protocol. (IPP Protocol uses Port Services 631/TCP.)

You must advise clients of the correct URL or IP Address of the IPP Server. To use a URL rather than an IP Address, you need to register the domain name for the URL.

Unless clients are using Windows 2000, you must provide your clients with the supplied IPP Client software. If it is not convenient to provide the CD-ROM, supply the IPP CLIENT.EXE file, located in the IPP folder.

Installing using IPP CLIENT.EXE

1. Run this program, located at d:\driver\ipp\ipp client.exe, to unzip the included files.

2. The IPP Setup program will then run.

3. Follow the prompts to complete the installation.

Chapter 9: DHCP Support for the EtherFast Wireless-Ready USB PrintServer To use DHCP, which assigns non-static IP addresses, you must have a DHCP server and DHCP management software. Otherwise, the PrintServers IP address will remain unknown, and connecting to it will impossible. In this case, ignore DHCP and configure the PrintServer for a static IP address as described in previous sections.

To enable DHCP, you must run the Bi-Admin program. By default, DHCP is enabled. When Bi-Admin loads, it scans the network for PrintServers and dis- plays a list of PrintServers. Highlight the PrintServer to be set up, and enter the PrintServers password if one has been assigned. Then click OK.

After entering the program and selecting the PrintServer to be configured, click on Configuration in the menu and choose TCP/IP from the drop-down field. The TCP/IP Configuration window will appear. Select Enable to enable DHCP, and then click Save to Device. You can exit the Bi-Admin program. To install the PrintServer driver, see Chapter 4: Windows Driver Setup.

4. If the connection can be established, and the printer on that port is online, the dialog box shown in Figure 8-5 will be displayed. This screen notifies you that the printer driver is not installed. Click the OK button.

5. Select the printer manufacturer and model to match the printer connected to the port on the IPP Server.

6. Click Next and complete the Wizard.

The IPP printer is now ready for use.

Using IPP Printers

The IPP Printer can be selected and used like any other Windows printer. If the IPP Server is not on your network, your Internet connection needs to be active.

If you wish to check the availability of the remote IPP Server, you can use the Query IPP Printer program installed with Add IPP Port.

An IPP Server may be unavailable for any of the following reasons:

It is powered off.

A printer problem has caused the IPP Server to cease responding, and a restart (reboot) is required.

The Servers IP Address has changed.

The Internet connection for the IPP Server is down.

Network congestion causes the connection attempt to time out.

If using the supplied IPP Client software, there are two settingsRetry Interval and Retry Countthat can be adjusted if you have problems connecting to the IPP Server.

Appendix B: About Bi-Directional Printing Normal printing only sends print signals from a PC to a printer. Bi-direction- al printing, also called bitronic printing, refers to a printers ability to do just the oppositetalk back to a PC to notify it of a print job status, paper jams, etc. This two-way communication technology can be found in HP, IBM, Panasonic, and other laser or color printers where close contact between the PC and print- er is key. In color printing, for example, the printer informs the PC of its con- stant status in order to mix color inks correctly for optimal quality output.

Bi-directional communication, communication from a printer to a PC, is nor- mally handled by a combination of the printer hardware and special software on your computer. Bi-directional printers generally have highly advanced par- allel interfaces. These printers often require special parallel ports in order to take full advantage of their features.

Using a bi-directional printer on a network poses unique challenges. Unlike a direct PC-to-printer connection in which a bi-directional printer can easily send its signals back to the host PC through the computers parallel port (which is normally located only a few feet away from the printer), a networked printer faces the problem of having to route messages bound for a particular PC through a large array of hubs, switches, file servers, and computers. Unfortunately, most printers are not equipped to handle the complexities of printer-to-PC communication across a network. That does not mean that they cant be used on a network, however.

Linksys designed the PrintServers to function with both regular as well as bi- directional printers. Standard print servers cannot work with bi-directional printers, but the PrintServer features a custom design to support both parallel as well as bi-directional parallel interfaces. However, the PrintServer cannot pass messages from the printer back to the printing PCthis limitation is sim- ply an industry standard, and not one of the PrintServer itself.

However, the PrintServer can check any printers online and printing status on the network using the Bi-Admin management utility software packaged with the PrintServer. The status-checking feature built into the management soft- ware does not require a bi-directional printer to function. If your printer came with special bi-directional software allowing you to monitor printer status, do

Appendix A: Troubleshooting If the PrintServer is not working correctly, follow the advice in this chapter. If you have trouble printing, see Chapter 3 first, and then go to Chapter 5. If this Troubleshooting section does not resolve your problem, please see Appendix H to contact Technical Support.

1. All the LEDs on the front of the PrintServer are off. Check the power supply and the power connection.

2. The PrintServers Status LED stays lit continuously. Reset the Wireless-Ready PrintServer by unplugging the power supply

and plugging it back in or pressing the Reset button on the back of the PrintServer.

3. I am using DHCP, and the PrintServer gets an IP Address conflict involving the PrintServer. If the PrintServer is left on when the DHCP server is turned off, the

PrintServer will retain its IP Address without informing the DHCP serv- er. Reset the PrintServer so it will obtain a new IP Address. This problem also arises if you assigned a static IP Address within the range used by the DHCP server. If so, use another address NOT within the range used by the DHCP server.

4. The PrintServers LAN LED is not lighting up. Check your cabling and make sure that the Link LED on your hub or

switch is lit up.

1. A printer connected to the PrintServer cannot print or prints garbage. Check the following:

1. Cable connection between the PrintServer and printer. 2. The printer driver in the application program or Windows matches

the printer. 3. Cabling distance is too long if it exceeds 10 feet.

2. The Configuration button on the Printer Status screen in Bi-Admin is grayed out, even though my printer is bi-directional. The button is unavailable until the printer has finished its print jobs and

sits idle.

Appendix C: About the Wireless- Ready USB PrintServers Software The PrintServer is fully compatible with Windows 95, 98, Millennium, NT, 2000, and XP.

When used with Windows, the PrintServer uses the TCP/IP protocol for net- work communication. Each computer on your network that needs PrintServer access will need to have the TCP/IP protocol installed. TCP/IP installation files are included on your original Windows CD-ROM.

Please be aware that although Linksys provides instructions for the setup of the TCP/IP protocol, these instructions are provided for reference only. Linksys will not provide technical support for the configuration and troubleshooting of the TCP/IP protocol. For full instructions on using TCP/IP, consult your oper- ating systems user guide.

if computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and dis- tribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.

DHCP uses the concept of a lease or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It's espe- cially useful in education and other environments where users change fre- quently. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses.

DHCP supports static addresses for computers containing Web servers that need a permanent IP address.

Domain - A subnetwork comprised of a group of clients and servers under the control of one security database. Dividing LANs into domains improves per- formance and security.

Driver - A workstation or server software module that provides an interface between a network interface card and the upper-layer protocol software running in the computer; it is designed for a specific card, and is installed during the initial installation of a network-compatible client or server operating system.

DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chip- ping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the orig- inal data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most nar- rowband receivers.

Firewall - A firewall is a set of related programs, located at a network gateway server, that protects the resources of a network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources to which its own users have access.

NetBEUI (NetBIOS Extended User Interface) - The transport layer for NetBIOS. NetBIOS and NetBEUI were originally part of a single protocol suite that was later separated. NetBIOS sessions can be transported over NetBEUI, TCP/IP and SPX/IPX protocols.

NetBIOS - The native networking protocol in DOS and Windows networks. Although originally combined with its transport layer protocol (NetBEUI), NetBIOS today provides a programming interface for applications at the ses- sion layer (layer 5). NetBIOS can ride over NetBEUI, its native transport, which is not routable, or over TCP/IP and IPX/SPX, which are routable proto- cols.

NetBIOS computers are identified by a unique 15-character name, and Windows machines (NetBIOS machines) periodically broadcast their names over the network so that Network Neighborhood can catalog them. For TCP/IP networks, NetBIOS names are turned into IP addresses via manual configura- tion in an LMHOSTS file or a WINS server.

There are two NetBIOS modes. The Datagram mode is the fastest mode, but does not guarantee delivery. It uses a self-contained packet with send and receive name, usually limited to 512 bytes. If the recipient device is not listen- ing for messages, the datagram is lost. The Session mode establishes a connec- tion until broken. It guarantees delivery of messages up to 64KB long.

Network - A system that transmits any combination of voice, video and/or data between users.

Node - A network junction or connection point, typically a computer or work station.

Packet - A unit of data routed between an origin and a destination in a network.

PC Card - A credit-card sized removable module that contains memory, I/O, or a hard disk.

PCMCIA - The PCMCIA (Personal Computer Memory Card International Association) is an industry group organized in 1989 to promote standards for a credit card-size memory or I/O device that would fit into a personal computer, usually a notebook or laptop computer.

Port - A pathway into and out of the computer or a network device such as a switch or router. For example, the serial and parallel ports on a personal com-

Infrastructure Network - An infrastructure network is a group of computers or other devices, each with a wireless adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point. An infra- structure wireless network connected to a wired network is referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a corporation scale, or when it is necessary to connect the wired and wireless networks.

IP Address - In the most widely installed level of the Internet Protocol (Internet Protocol) today, an IP address is a 32-binary digit number that identi- fies each sender or receiver of information that is sent in packet across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address youre sending a note to. At the other end, the recipient can see the IP address of the Web page requestor or the e-mail sender and can respond by sending another message using the IP address it received.

IPX (Internetwork Packet EXchange) - A NetWare communications protocol used to route messages from one node to another. IPX packets include network addresses and can be routed from one network to another.

ISP - An ISP (Internet service provider) is a company that provides individuals and companies access to the Internet and other related services such as Web site building and virtual hosting.

LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).

Mbps (MegaBits Per Second) - One million bits per second; unit of measure- ment for data transmission.

MIB (Management Information Base) - A set of database objects. This set con- tains information about a specific device for utilizing SNMP.

If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

Static IP Address - A permanent IP address that is assigned to a node in an IP or a TCP/IP network.

Subnet Mask - The method used for splitting IP networks into a series of sub- groups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets.

Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical cir- cuit.

TCP (Transmission Control Protocol) - A method (protocol) used along with the IP (Internet Protocol) to send data in the form of message units (datagram) between network devices over a LAN or WAN. While IP takes care of handling the actual delivery of the data (routing), TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for effi- cient delivery over the network. TCP is known as a connection oriented pro- tocol due to requiring the receiver of a packet to return an acknowledgment of receipt to the sender of the packet resulting in transmission control.

TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com- munication language or set of protocols for communications over a network (developed specifically for the Internet). TCP/IP defines a suite or group of protocols and not only TCP and IP.

Throughput - The amount of data moved successfully from one place to anoth- er in a given time period.

Upgrade - To replace existing software or firmware with a newer version.

URL (Uniform Resource Locator) - The address that defines the route to a file on the Web or any other Internet facility. URLs are typed into the browser to access Web pages, and URLs are embedded within the pages themselves to pro- vide the hypertext links to other pages.

USB (Universal Serial Bus) - A plug and play interface between a comput- er and add-on devices (such as audio players, joysticks, keyboards, telephones,

puter are external sockets for plugging in communications lines, modems and printers.

PrintServer - A hardware device that enables a printer to be located anywhere in the network.

RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices.

Router - Protocol-dependent device that connects subnetworks together. Routers are useful in breaking down a very large network into smaller subnet- works; they introduce longer delays and typically have much lower throughput rates than bridges.

Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services.

SNMP (Simple Network Management Protocol) - A widely used network monitoring and control protocol. Data is passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc.) to the workstation console used to oversee the net- work. The agents return information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.).

Software - Instructions for the computer. A series of instructions that performs a particular task is called a program. The two major categories of software are system software and application software. System software is made up of control programs such as the operating system and database management sys- tem (DBMS). Application software is any program that processes data for the user.

A common misconception is that software is data. It is not. Software tells the hardware how to process the data.

Spread Spectrum - Spread Spectrum technology is a wideband radio frequen- cy technique developed by the military for use in reliable, secure, mission-crit- ical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is con- sumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast.

USB supports a data speed of 12 megabit per second. This speed will accom- modate a wide range of devices, including MPEG video devices, data gloves, and digitizers. It is anticipated that USB will easily accommodate plug-in tele- phones that use Integrated Services Digital Network and digital private branch exchange.

Since October, 1996, the Windows operating systems have been equipped with USB driver or special software designed to work with specific I/O device types. USB is integrated into most Windows operating systems. Today, most new computers and peripheral devices are equipped with USB.

A different plug-and-play standard, FireWire/IEEE 1394, is designed to sup- port much higher data rates and devices such as video camcorders and digital video disk (digital versatile disk) players. Both standards are expected to exist together, serving different device types.

UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electro- magnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.

WAN (Wide Area Network)- A communications network that covers a rela- tively large geographic area, consisting of two or more LANs. Broadband com- munication over the WAN is often through public networks such as the tele- phone (DSL) or cable systems, or through leased lines or satellites. In its most basic definition, the Internet could be considered a WAN.

Workgroup - Two or more individuals that share files and databases.
