To turn off Windows protected print mode:
- Select Start.
- Go to Settings > Bluetooth & Devices > Printers & scanners.
- Scroll to Printer Preferences.
- Under Windows protected print mode, select Turn Off.
- Select Yes to confirm.
After it is disabled:
- Non-compatible printers can be installed again.
- Any non-compatible printers that were removed must be manually reinstalled.
If the option to turn it off is unavailable and Windows says it is managed by policy, it was enabled through Group Policy or device policy and must be changed by the administrator.
