I have a HP office jet v40 connected to a XP pc. I recently added a Windows 7 lap top to my home network. I have the printer added on the Windows 7 pc, but I can not print to it. Shows items spooling, but nothing prints. I tried updating the drivers, but HP says the Windows 7 has the drivers needed. The lap top is accessing my network thru a wireless router, just FYI. Can you help? Thank you.
