i am preparing your link now
by the way, are you using windows 7? (or windows vista or XP)
(what is the version of your windows)
so i can give you the correct driver
here is your link: http://tinyurl.com/3molbz8 <<-----please download it (to your desktop) and then install
it is the software that will install your lexmark on your vista.
