For example, are all computers and the printer connected via a router, or is the printer connected to one computer, and you want the other computers to be able to access it?
Has the printer software been installed on all computers?
With the network open and running, have you "found" the printer in the wizard using the browse option?

I'm trying to install a printer over the network at the office but the "Add Printer Wizard" seems to always freeze on me (do any of these stupid wizards ever work?!?!). I'm choosing connect over a network and I'm punching in the printer's address. Then when I hit next, it freezes. It does add a printer with the correct hostname to the printer list while it is frozen, but its status is always "opening".
I thought this was a firewall issue, but the same thing happened with my Norton firewall disabled. I am also able to ping the printer successfully over the network.
The printer is an HP LaserJet 5100.
Any ideas?
