Hi @Matt Rothschild ,
Thanks for the details!
After researching, The IPP Class Driver is a generic protocol-based driver. After recent Windows 11 updates, its advanced options were reduced, which is why you only see Letter size and Grayscale in the settings. Features like Japanese Postcard size and color printing require a device-specific driver from Canon.
- Canon does not provide an official Windows 11 driver for the SELPHY CP1500 series at this time: Canon SELPHY CP1500 Support Page
- Canon’s support pages only list firmware updates for Windows 11, not installable drivers: Canon Australia Firmware Update
- Community feedback confirms the printer relies on IPP/Mopria standards for Windows printing: End of servicing plan for third-party printer drivers on Windows
There are possible workarounds you could try:
1. Check Canon Support for Updates
Contact Canon Support directly to confirm if a Windows 11 driver is planned.
2. Install Windows 10 Driver in Compatibility Mode
If Canon offers a Windows 10 driver for similar models (e.g., CP1300), try installing it in compatibility mode.
3. Use Canon’s Photo Printing Utility
This can restore color and custom sizes, though it may not fully integrate with your workflow.
4. Prevent IPP Driver Auto-Selection
Add the printer manually and select the Canon driver (if installed) instead of the IPP Class Driver.
5. Temporary Rollback
If this issue started after a recent Windows update, rolling back to the previous version can restore functionality until Canon or Microsoft releases a fix.
Hope this helps! If you find suggestions helpful, please kindly consider following this link instruction.
