"UnsupportedProtocol" prints on paper when printing with DeviceHub in PitneyShip, PitneyShip Pro, or PitneyShip Enterprise
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
- Solution 2: Check compatible envelope printers or print to PDF
Download and install the latest printer driver for your printer from the printer manufacturer's website.
- 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.
