My computer runs Vista and is connected to my printer via a printer port. A second computer running Windows XP is connected to the same printer port. I can print Word documents with no problem. E-mail messages and browser pages print all black. I do not have any of these problems when printing from the second computer using Windows XP. I did not have these problems when both computers connected to the printer through a LAN. Before I installed the print server I downloaded the HP drivers for my printer model for use with Vista. The second computer running XP, which does not have any printing problems, uses a different HP driver that is for use with XP. My first thought was that the problem was caused by the print server, but I don't think that could be the case because the XP computer does not have any printing problems. I would appreciate any help someone can give me. Thank you for taking the time to read this post.
