Chapter 1: The basics
Connecting the
printer to your
computer
To print from software loaded on your computer, your
printer needs to be connected to your computer with
either a parallel interface cable or a USB cable.
Using a parallel
interface cable
Your printer requires an IEEE-1284 compliant parallel
cable. We recommend Lexmark part number 1329605
(10 ft) or 1427498 (20 ft). If you use something other
than an IEEE-compliant cable, you may not be able to
use all of your printer’s functions.
1
Make sure your printer is turned off.
2
Plug the parallel interface cable into the
connector on the back of the printer.
3
Push the metal clips toward the plug until they
snap in the notches on the plug.
4
Attach the other end of the parallel cable to your
computer.
5
Turn on the printer.
