I have XP Pro (SP2) OS on a Dell XPS 600. Without ANY new hardware/software installs/upgrades my Dell All-in-one Photo 964 printer decided not to print anymore. I can copy, but not print, including test pages of course. In Device Manager (see attached pic's) under imaging devices I had the yellow exclamation point and the reason given as Code 19, Registry corrupted, blah, blah. But the Printer was not flagged. I ran Registry Fix to no avail. Tried to go back to a prior registry backup point(s), a prior restore point(s), uninstall drivers/reinstall drivers, uninstall & reinstall printer software, all to no avail. In Microsoft's database code 19 is dealing with filters listed for cd/dvd drives. Before I drop kick this thing and reinstall the the OS and start over any body have any cool knowledge out there. I have some basic reasoning brain drain ability with PC's but need help with this please. I hate to take the time to reformat and install all the crap I have on here. Any further info you may need please ask also. Thank you very much.
