This printer is shared on a vista home basic pc via usb because the wireless is faulty. If i browse to from a windows 7 home premium pc and add the printer it automatically install the driver and prints 100%, from any windows 7 pro pc when i try to add the printer, it installs a driver, then says completing installation, but then gives an error, saying cannot connect to printer. I have even installed the driver from the cd. After it still did not work I ran the windows 7 compatibility tool. still no luck. Help please.
