If it's a standard wireless printer, it should just be as simple as opening Printers and discovering the printer on the network. Setting it up and installing the driver is the same as a local one. It may have a few different protocols.
It's a good idea to set a static IP for the printer (either on the unit or DHCP Reservation on the router) since the computer may not "find" the printer another day if the printer is assigned a different (dynamic) IP.
