Hello here! i have tried to install my lexmark x5150 to my compacq laptop, and cant get it to print, i have installed the disc countless times wiyh out any progress can you help?

Try this:
first uninstall the disc's software
than restart the laptop
if correct it will automaticly detect your printer and ask for the disk.
cancel the installation.
Insert the disk and cancel the automatic running program for installation.
go to start, printers, add new printer and follow the steps from there untill it says "have disk" click on have disc and brose to your CD drive. It will automatically indicate which program it requires, search on the disc that program and click OK and continue the steps.

Reason: automatic installations from manufacturers sometimes do not install all files needed by windows, installing via windows itself it will automaticcaly pick the correct files from the disc.
