EtherFast 10/100 PrintServers
Linksys designed the PrintServer 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 PC. This limitation is sim-
ply an industry standard.
However, the PrintServer can check any printer’s online and printing status on
the network with the Bi-Admin management utility software packaged with the
PrintServer. The status-checking feature built into the management software
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 not
use it with the PrintServer - the software is most likely not network-capable.
For best results, turn off the printer’s bi-directional function either by (1)
removing any bi-directional printing software from your network computers,
and/or (2) turning off the printer’s bi-directional print feature inside of the
printer’s on-board menus (if it has menus). Your printer’s user guide should be
able to provide specific instructions for doing this.
The PrintServer is fully compatible with Windows 95, 98, Millennium, NT,
2000, and NetWare.
When used with Windows 95, 98, Millennium, 2000 and NT, the PrintServer
uses the TCP/IP protocol for network 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 95,
98, Millennium, NT, or 2000 CD-ROM. For tips on installing TCP/IP, see the
section called Setting Up TCP/IP and IPX Protocols.
When operating under NetWare, the PrintServer uses IPX/SPX for communi-
cation, which is built into the NetWare network operating system. Most com-
puters need only be able to log into the network in order to print after the
PrintServer has been configured.
NetWare 5.x supports the use of both IPX/SPX and TCP/IP. Instructions for the
setup and configuration of IPX/SPX are provided in the NetWare 5.x section of
this user guide. TCP/IP instructions are provided in “Appendix C: Setting Up
TCP/IP and IPX Protocols.”

A switch, hub, or similar device is connected to the LAN port with regular UTP
Category 5 cabling. Connect one end of the cable to the LAN port, then con-
nect the other end to an uplink port on your hub or other device.
Linksys does not provide any technical support for connections made with
crossover cables.
Normal printing only sends print signals from a PC to a printer. Bi-direction-
al printing, also called bitronic printing, refers to a printer's ability to do just
the opposite- talk 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 computer’s 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
can’t be used on a network, however.
