Allen Datagraph has tested several USB to Serial devices available on the market and found that most do not work in our application as a printer driver output device. We recommend using only the BAFO-800 or BAFO-810 USB to Serial Converters. You may order this device directly from Allen Datagraph at the Phone Number below. New cutters ship with a Bafo 810 external usb to serial device.

The usb drivers are on the CD supplied with the cutter. If you need the drivers you can also download the driver here and run the setup.
