       Download  firmware to a device that requires downloaded firmware to function. (Note: Most printers do not

       Use USB IDs to specify printer:
              -s bbb:ddd, where bbb is the USB bus ID and ddd is the USB device ID.  The  ':'  and  all  leading
              zeroes must be present.

              -d<device-uri> or --device=<device-uri>
