I have a Brother HL-2030 printer connected to a Win 7 desktop computer. The printer is set as shared. I can print to the printer from other computers. Plugging the printer into the Surface usb port works ok ... the printer prints. Brother confirms that the RT core has the proper driver. When adding a printer, the Surfaces correctly discovers the printer hooked to the desktop computer. I cannot add the shared printer to the Surface. It connects to the printer but then can't find a driver. any suggestions ????
