I recently upgraded my computer to a Pentium duo core with 2 gigs of ram.. All of my information was copied over to my new hard drive and everything works just fine except the all in one. I had a parallel port installed on the computer because my printer is not a usb one. This "all in one" worked before on my computer with XP. I do know that I had some issues getting it to work when I originally upgraded to XP but now cannot remember what they were. Anyone have any ideas?
