Greetings,
The MP210 is not officially supported under W11. Drivers for W10 might work with some or limited functionality. If its been less than 10 days, you can easily rollback to Windows 10.
Other options, include uninstalling and reinstalling the device using the W10 drivers in compatibility mode, but again, there is no guarantee of full support for a 15 year old printer..
