i am in a dorm room setup. i have a laptop and a desktop, and I want to set up my printer so I can wirelessly print from my laptop. Yes, my laptop is wireless, but my printer is not. I have a U.S. Robotics maxG router...it has a USB port as well. Do I need a wireless modem? Or can I just hook the printer and the router with a USB cord, and then have my laptop connect with the router? my printer is a Lexmark Z32
