When printing with DeviceHub, "UnsupportedProtocol" prints on the paper.


The printer driver being used is not compatible with DeviceHub.


Solution 1: Install a different printer driver

Download and install the latest printer driver for your printer from the printer manufacturer's website.

Solution 2: Check compatible envelope printers or print to PDF

  • If printing on envelopes, and the issue is not resolved, please refer to Compatible printers and scales.
  • If printing stamp sheets or shipping labels, choose Print to PDF instead of your printer in the Print Options window.
