the preferred option when there is a great deal of distance between the printer and computer, or when a parallel interface is 
not available.
Note:A serial interface card is required and can be purchased separately.

10Press   until the printer returns to Ready.
Verifying the IP settings
1Print another network setup page. Look under the “TCP/IP” heading, and make sure the IP address, netmask, and 
gateway are correct. See Printing a network setup page if you need help.
2Ping the printer, and verify that it responds. At a command prompt on a network computer, type ping followed by 
the new printer IP address (for example, 192.168.0.11).
Note:On Windows computers, click Start
Æ ProgramsÆ Command prompt (or AccessoriesÆ 
Command prompt if using Windows 2000).
If the printer is active on the network, a reply is sent.
After the TCP/IP settings are assigned and verified, install the printer on each network computer.
Windows
In Windows environments, network printers can be configured for direct printing or shared printing. Both network printing 
methods require the installation of a printer driver and the creation of a network printer port.
Supported printer drivers
Windows system printer driver
Lexmark custom printer driver
Updated system and custom drivers are available on the Lexmark Web site at www.lexmark.com.
Custom drivers are available on the drivers CD.
Supported network printer ports
Microsoft Standard TCP/IP port—Windows 2000, Windows XP, and Windows Server 2003
LPR—Windows NT 4.0
Lexmark Enhanced TCP/IP port—Windows 98 SE/Me, Windows NT 4.0, Windows 2000, Windows XP, and 
Windows Server 2003
For basic printer functionality, install a printer driver, and use a system network printer port, such as an LPR or a Standard 
TCP/IP port. The printer driver and port let you maintain a consistent user interface for use with all the printers on the 
network. Using a custom network port provides enhanced functionality, such as printer status alerts.

Installing drivers for network printing
Shared printing using Windows NT 4.0, Windows 2000, Windows XP, or 
Windows Server 2003
Note:Install the printer software before connecting the USB, parallel, or serial cable.
After connecting the printer to a Windows NT 4.0, Windows 2000, 
Windows XP, or Windows Server 2003 computer (which will act as a server), 
follow these steps to configure the network printer for shared printing:
1Install a custom printer driver.
aLaunch the drivers CD.
bClick Install Printer and Software.
cClick Agree to accept the license agreement.
dSelect Suggested, and click Next.
The Suggested option is the default installation for local and 
network-attached setup. To install utilities, change settings, or customize device drivers, select Custom, and 
follow the instructions on the screen.
eSelect Local Attach, and click Finish.
Follow the instructions on the screen. It may take some time for the drivers to load.
fClose the drivers CD installer application.
gConnect the USB cable, and turn on the printer.
The Plug and Play screen appears, and a printer object is created in the Printers folder of the computer. The 
printer is shared in step 2: “Share the printer on the network.”
Note:USB support is not available for Windows NT operating systems. Use a parallel cable instead. The 
Plug and Play screen will not appear for Windows NT.
hPrint a test page to verify printer installation.
2Share the printer on the network.
aClick Start

printer.
fClick OK. 
Note:If files are missing, prompts may appear to request the server operating system CD.
gCheck the following to make sure the printer was successfully shared.
The printer object in the Printers folder now has a shared indicator. For example, in Windows NT 4.0, a 
hand appears under the printer object.
Browse Network Neighborhood. Find the host name of the server, and look for the shared name 
assigned to the printer.
