I share a older HP 6310xi AiO with an XP machine via a router. As I recall, I downloaded drivers for this machine (Windows 7) from HP and had to install those first. If I remember correctly, there were specific drivers for a LAN printer. Then it was just going through the Add Printer process. (I think--It was past yesterday) It works great. I can set the printer options from either machine for what I'm printing at the time. The printer OEM should have the process documented. At least HP did at the time.
