networkprinting

Hello,

I've a HP 970cxi in excellent condition. It's hanging on a PC (WXP) with
USB-cable in a wireless network with 3 PC's. Printing within this network
isn't a problem using XP and 98SE.

Since a few weeks I've also a laptop with Vista Ultimate. I tried to print
from my laptop to this HP970cxi at the XP-PC. Vista found the printer and
installed it. I could not find the instructions within Vista to install this
printer hanging on another PC in a (wireless) network. In XP this posibility
is normal.

How can I print with Vista in a network?
