Confirm that Windows Protected Print Mode is properly configured on target devices using both registry checks and user interface verification.
On a target device, open PowerShell as Administrator and run:
Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows NT\Printers" -Name "EnableWindowsProtectedPrintMode"
Expected output for enabled WPP:
EnableWindowsProtectedPrintMode : 1
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT
PSChildName : Printers
PSDrive : HKLM
PSProvider : Microsoft.PowerShell.Core\Registry
Also verify through the Windows Settings interface:
- Open Settings > Bluetooth & devices > Printers & scanners
- Click Printer preferences
- Look for Windows protected print setting (should be grayed out/enforced)
Warning: When WPP is enabled, non-Mopria printers will be automatically removed from the system. Document affected printers before deployment and have a rollback plan ready.
Verification: Registry value shows 1 for enabled or 0 for disabled, and the Settings UI reflects the enforced state.
