Hii my name is Luna Falon i am from the technical team if you are facing a problem then you can visit our site. Resolving a Canon printer offline issue on Windows 10 involves a systematic approach. First, check the printer's physical connections, ensuring cables are secure. Verify Wi-Fi connectivity and router status. Navigate to "Devices and Printers" from the Control Panel, right-click the offline Canon printer, and select "See what's printing." Clear any pending print jobs. If the issue persists, update or reinstall the printer drivers. Open "Settings," select "Devices," then "Printers & scanners," and remove the printer.
