All-in ones are a different story. They are bi-directional printers. If they have a print server built in, most will do all, ( print,scan, etc) by way of the network from any computer. You MUST install the drivers on all the computers. Most will not pass them between computers. Many also have to talk (thru the network )to one computer. You direct all other computers to talk to that computer to print. You did not say what OS is on your computers. Printing from a XP computer to a W7 machine can bring other issues in to play. Most all in one will print from other computers but some will not scan to another computer. Robert
