I have a user with a Vista Ultmate Dell Lat. D630 that suddenly had issues printing. Everytime she prints to her USB, the document doesn't print. When I look at the properties of the print job, the status shows error, but I never get any details for the error. So I removed the printer, reinstalled and same thing. Next test I tried was downloading the software from HP to make sure we had the latest version. Still no luck. I have tried PCL5 and PCL 6 drivers. I also tried to use a different model USB printer. It was an HP 1022. Unfortunately it didn't install automatically and she didn't have time for me to download the software and install manually.
