I finally got a Mac (first one) and it's great, except my printer won't work with it. It's the 2 ghz 1gb RAM white macbook and the printer is a 6 year old HP Deskjet 648c. I can print test documents, but whenever I try and print something from safari or another program it always says "Jobs Stopped". I try to start them again, but it never works. I downloaded the latest drivers for it already. Please help... this is driving me nuts.
