I have what appears to be a corrupt printer driver installed on an XP Home system. How can I uninstall it short of reformatting the drive and starting over? My daughter has a Lexmark Z705 Inkjet attached to a new eMachine (I know - first mistake ) that is running XP Home. When I installed the driver from the CD-ROM that came with the printer, it threw up a run-time error dialog and then displayed the "Print Test Page" dialog. Anytime you try to print the driver bombs. Also, if you reboot the printer disappears from Device Manager. I don't have a way to get the details for the error as the computer is 150 miles away from me. Can I simply install a new driver that I just downloaded? I'm thinking that it may be better to uninstall the corrupt one first but can't figure out how to do so.
