If your Canon printer is not being detected in Windows 11, you can try the following troubleshooting steps:

Check physical connections: Ensure that the printer is properly connected to your computer via USB or network connection. Make sure the cables are securely plugged in on both ends.

Verify printer power: Ensure that the printer is turned on and has power. Check for any error lights or messages on the printer's control panel.

Update printer drivers: Outdated or incompatible printer drivers can cause detection issues. Visit the Canon website and download the latest drivers specifically designed for Windows 11. Install the drivers and follow any on-screen instructions.

Restart printer and computer: Sometimes a simple restart can resolve temporary glitches. Turn off the printer, unplug it from the power source, wait for a few minutes, then plug it back in and power it on. Also, restart your computer to refresh the system.

Check device manager: Open the Device Manager on your computer and look for any unrecognized or problematic devices. If you find any, right-click and choose "Update driver" to search for updated drivers online.

Disable firewall or antivirus: Temporary disable your firewall or antivirus software and check if the printer is detected. Sometimes these security programs can interfere with printer detection.

Try a different USB port or cable: If you're using a USB connection, try connecting the printer to a different USB port on your computer. Additionally, try using a different USB cable to rule out any cable issues.
