We have an HP 2605dn printer connected to a Windows XP machine and networked to our office. We recently purchased two new PCs and have Windows 7 x64 on them. In trying to set up connection on the new machines to the networked HP printer, we can see the printer referenced in the 'Add a Printer' dialog box, but it will not connect. It says that it is "looking for .INF on <UNKNOWN>" and requires us to find this file before proceeding.
What could be causing this? Is it because the host PC for the printer is on XP?
