If you have a wireless print server that's compatible with your printer and a wireless router located within radio range, it's not that much different than setting up any other wireless device. The print server should come up with some kind of "wizard" or discovery software utility to aid in setting it up. As a hint, I prefer print servers to have a static IP address for troubleshooting purposes. Such allows me to ping the server makes access through a browser quite easy.
I have a wired printer which I want to make wireless so I can print from a laptop. The USB printer is connected to a desktop computer in a room without a router. If I purchase a print server, how can I make this work without having the router in the same room as the printer? Can I use a different router in that room, or will that conflict with the current router? The desktop is running XP, my laptop is running Windows 7
