I have a laserjet 4100 printer and I've changed machines to Windows 7. This particular printer has a parallel port and nothing else. I have it hooked up to an XP machine and it works fine. My issue is I'm trying to share this printer and allow my Windows 7 machines to print to it - however, it can't find a driver? I've downloaded and installed the universal print driver on the Windows 7 machines but that' not working either. What can I do?
