Most printers today don't need disks. Go to the Lexmark site and look for their download section. It will usually ask for your model and will tell you if it has the newest drivers for your printer. Even if you found your disk it would probably be out of date. Downloading from the site gives you the most current. I did this with my new MacBook Air laptop and easily downloaded the drivers for the printer. I also discovered that Apple.com also downloads printer drivers to Mac so I didn't even need to go out to the printer manufacturer.
