I have a desktop computer downstairs in my office and a laptop I use upstairs. We recently had a wireless internet system installed, this is not cable or dsl. A router (Belkin F5D7230-4) is used for wireless internet to the laptop. Can this system be used to print from the laptop and access files on the office desktop computer? Do I require more equipment to do it? The printer is connected to the office computer, it is a Canon i850 using usb cable.
