If you can't connect to any serial port, you may need to install drivers for the CH340 USB chip. To find your serial port (also known as COM port), unplug the printer, and see which com ports are currently listed. Plug the printer USB cable in, and see if any new COM ports appear. Those will likely be your printer. If you can’t find the right com port, or your device is not detected, you may need to install drivers for the CH340 serial to USB interface chip in the printer. Mac CH340 serial drivers are [[http:// | If you can't connect to any serial port, you may need to install drivers for the CH340 USB chip.
