Lexmark USB-Printer prints strange characters

Hi! I just installed Windows XP on my Parallels Desktop (the newest version). I have a Lexmark E232 attached through USB to my imac and I installed the printer drivers from Lexmark on my virtual XP machine.

If I print a testpage (or anything from any other app) I only get several papersheets with strange symbols in courier-font. I guess the printer does not understand the information.

Anyone here, who has a idea how to get further? I urgently need to print some files on my XP machine!

Thanks!
