I need help with my Lexmark Laser Printer (http://www.lexmark.com/publications/.../4800/4800.jpg
) and it stopped working when I updated my windows from Vista to Windows 7. I have ink cartridges that are old now and when I tried to print in the past, it says "Missing Cartridge - consult the manual" even though I place the cartridge properly. I believe it is not reading it right. However, the printer is read from my computer, and I can perfectly scan anything - the problem is just the printing. Anything feedback would be appreciable.
