I want to know what i can do or what i should buy. Right now i have 4 printers in the house, 3 printers on three computers, and one color laser through the ethernet. The problem is, we want to use our other printers, like our bw laser when the computer that is hooked up to it is off. The bw laser is the most important. Do i need to buy an airport express to get this to work? I have only one mac, and the rest are windows. Is there anything else that i can buy that is cheaper so i can buy one for each of my printers? I really dont need any of the other features of the airport extreme because i already have wireless.
