I have a mixed PC environment. We have PC running 98 and XP, some of the XP machines are 64 bit. We recently added Windows 7 PCs in to the mix. We want to share printers and we can browse to the printers but they won't install between the windows 7 64 bit machines and the rest of the PCs. Sharing between the 32 bit machines is no problem. I am looking for a disc with the "additional drivers" to be installed. I believe the problem is the 32 bit machines have installed a driver that is inconpatible with the 64 bit or windows 7 machines. Any help please?
