I have a hybrid home network with two wired (win XP) and two wireless (win Vista) and (win 7) computers. Each computer can see the others on the network, "WORKGROUP". My usb printer (HP Deskjet 932c) is connected to one of the wired XP machines. Except for the win 7 machine, all can use my printer. When I try to add a printer to the win 7 machine I dead end at a dialogue informing me that win 7 can not find the appropriate drivers on the network. As shipped, win 7 has the necessary drivers. What am I doing wrong?
