Adding a printer

Hello out there!

I'm trying to setup my wireless notebook with an HP 2575 printer to be
recognised on my LAN and all I get from Vista is it can't connect to the
printer. I have set the neccessary conditions for the printer sharing and
also admin permissions. I can only get the printer to be recognised as a usb
connection. I'm using a Linksys router hung off a cable modem. Can anyone
help out?
