To fix a Canon printer offline issue, first check the Wi-Fi or USB connection and ensure the printer is powered on. Restart the printer, computer, and router to refresh connections. Set the Canon printer as the default printer and disable the “Use Printer Offline” option in Windows settings. Updating printer drivers and clearing pending print jobs can also restore normal printing quickly.
