My HP Color LaserJet model 3550 has not been able to print ever since my upgrade to Tiger. The drivers show up and everything looks like a go although when I go to print a document the program on my computer showing the status of the printer switches to "Stop Printing". I click start printing. After a few seconds it goes back to stop printing. He keeps doing this. Any ideas? It would be a real shame if I couldnt use this printer now because of Tiger. It's an $800 printer.
