I have an expen$ive HP printer (1200pages an hour type expensive) that's supposed to be a "wireless network" printer that I've never been able to make work correctly as a network device.... let alone as a wireless network
printer, nor has anyone else
the network part of the printer not working is likely why I have it, because I got it from a friend who is a sys-admin for a fortune 100 company
But as I have multiple desktops on my home network that are "always on"
(24/hrs/365days) I just connected it to one of them and let Windows 7 Homegroup allow for full printer sharing within the homegroup.
It works as a network printer when physically connected to a windows7 computer via "Homegroup" and printer sharing.
IF you have not setup a "Homegroup" in a Windows 7 home network environment the one thing you need to do is be careful about naming your computers before you create a homegroup AND being careful about which computer you initially create the homegroup with before "joining" the other computers to it.
