My company has several HP1300 LaserJet printers on desks that have developed an extremely frustrating issue. They are printing multiple pages on one sheet of paper. When printing only one page, no problem. But, when printing a multiple page document all pages are printed on top of one another on one sheet of paper. This started all of a sudden, and all of my 1300's are doing it - no other model. I have tried uninstalling the printer, deleting the driver and reinstalling - didn't help. I have tried using drivers for similar printers - didn't help. HP "customer support" is next to impossible to get on the phone. Anyone have any thoughts?
