Windows 11 may fail to recognize a printer even when it is powered on and ready. This issue can occur after system updates, restarts, or when switching to a new device. To resolve it, follow these steps:
1. Ensure all connections are secure, including checking for a loose USB cable, a powered-off WLAN printer, and the correct network connection for wireless printers. Restarting both the printer and PC may help.
2. If the printer is not recognized, manually add it by going to Settings > Bluetooth & devices > Printers & Scanners and selecting Add device. If it still doesn't appear, use the "The desired printer is not listed" option to start the setup wizard.
3. Update the printer drivers by visiting the manufacturer's website to download the latest software compatible with Windows 11 for your printer model.
4. If these steps do not resolve the issue, use the built-in repair tool by going to Settings > System > Troubleshooting > Other troubleshooters and selecting the Printers troubleshooter.
If problems persist, consider the possibility that the printer itself may be faulty or outdated.
