How to Enable Windows Protected Print Mode

To enable protected print mode, open the Windows Settings app with Windows+i
and navigate to Bluetooth & Devices > Printers & Scanners. Then, scroll to the Printer Preferences section
and click “Set Up” next to Windows Protected Print Mode.

You’ll be prompted to confirm you want to enable protected print mode; if your printer or other devices aren’t compatible,
you’ll receive a warning. Click either “Yes, Continue” or “Cancel.”

Once enabled, you can turn protected print mode back off in the same place in the settings app by clicking “Turn Off”
