No Group Policy setting in the provided documentation prevents Windows protected print mode from replacing a vendor driver while keeping Canon MF Scan Utility compatibility.
Supported facts from the documentation:
- Windows protected print mode disables third-party print drivers and enforces the Windows IPP/Windows Ready Print path for Mopria certified printers.
- If Windows protected print mode is enabled, legacy driver-based printing scenarios are not the intended model.
- Windows protected print mode can be enabled by Group Policy at: Computer Configuration > Administrative Templates > Printers > Configure Windows protected print
- The platform is designed so users can revert back to legacy (driver-based) printing if the printer is not compatible.
For a Canon device that depends on the Canon driver for MF Scan Utility integration, the supported approach from the documentation is to use legacy driver-based printing instead of Windows protected print mode on those machines.
If the Canon driver has already been replaced and scanning integration stops working, the documented recovery steps are:
- Open Settings > Bluetooth & devices > Printers & scanners.
- Select the printer and choose Remove.
- Restart the PC.
- Add the printer again so Windows installs the recommended driver, or install a compatible manufacturer driver if Windows does not provide one.
- If the problem started after a recent driver update, open Device Manager > Printers or Print queues > printer Properties > Driver and use Roll Back Driver if available.
If Windows protected print mode was intentionally enabled through policy, disable that policy on devices that require the Canon driver and MF Scan Utility compatibility.
