My LaserJet HP IIP was connected to a new Dell w/ Vista in June using a Parrallel to USB cable. Vista found the printer & I installed the Drive rfound in Vista. It worked fine from June '08 to Oct' 08. The printer no longer prints from the PC but prints self-test internally pages. Printer shows no error msgs in the it's display but the PC printer que it says 'error.' Hp says I'm supported by the driver they placed in Vista. Dell has tried to make it work but failed. I took the printer to my old Sony w/ XP and using a LTP port and Parrallel cable it works fine. But when I use a Parrallel to USB cable, it acts as on the Dell-Vista. Changing to a new Parrallel to USB cable does not fix the problem. What should I do?
