If you already have a home network then the easiest and cheapest way(its free) is to simply connect the printer to one PC and then share it as you would a folder. If you dont have a network then you could buy an printer switch - it lets you connect multiple inputs to one output. You can pick up a switch for around �15 for parrallel connection or �20 for usb.
