Suddenly in the past several days, I am unable to print PDF files from my PowerBook 17" tp my HP DeskJet 6122. I have tried repairing permissions (shot in the dark), but this doesn't help. When I send the print job to the printer, it tries to start the printer connection, and after 10-15sec of trying it stops all printer jobs and bottlenecks the queue. I do have the most updated printer driver installed. Anyone have a suggestion?
