Hello,not sure where to properly place this, but, I am having trouble networking an HP LaserJet 4100 series printer from a Windows XP computer to my Windows 7 laptop. I have searched here and Google and the forums on here helped with the initial issue of the password being asked. That has been taken care of. I am able to search for and find the printer properly on the network, however when I select the printer it says that there is no valid driver found. The printer connects to the XP computer VIA parallel port. I ordered a USB to Parallel converter and I successfully connected the printer DIRECTLY to my laptop and it installed itself without the need for a special driver. So it prints successfully from either computer when connected directly but when I have it connected to the desktop and I try to network it, I still get the error that there is no valid driver. Any help would be appreciated. I hope this wasn't too long of a post.
