You are not the only one looking for a linux driver for this printer. The printer is not listed here -->

Lexmark is not a linux friendly company. They seem to have no interest in open software. I did a google search on the priner, every link I found was another person looking for a driver.
Just for fun I tried Lexmarsk's web site. It only lists windows drivers. If you need a printer for linux, have a good look at the link above BEFORE you buy it.
I have had good success with HP printers, and Brother printers. Epsom also support linux.
