Hi, I recently bought a new computer, and there is no 25 pin plug in. It runs Windows 7. I have an old LaserJet 4 which still works great. Well, actually, it doesn't work at all. I bought a usb adapter for the 25 pin plug in. When I plug it in, it beeps, says it's installing the drivers for the new software, shows up under printers as an HP LaserJet 4, and then won't print. Nothing happens at all, and it says error in the printing queue. Can anyone offer any suggestions?
