Most people (dozens of them) on here with a Lexmark printer problem just want the device driver for their printer because, like you they don't have the CD.
A good place to start looking (the most appropriate place really) will be the manufacturer's web site - I think you may be able to get pdf user guides too.
Your question by-the-by, is in the category, Video Satellite Receivers.
Good luck...
