hello. very odd thing happened - my printer stopped working with my mbp that has leopard on it. there is also a G5 and Cube connected to my airport extreme, both with Tiger. the G5 is connected to the network wirelessly in the other room, and nothing happens when i print on that computer either. however, my cube, which is connected directly to the router, prints fine. i tried both wirelessly and directly connected with my mbp, but both ways don't work. i have a samsung ml-1740. has anyone else had problems like this? please HELP!
