If your Canon printer shows "Offline," check the connection—ensure it's properly linked via USB or Wi-Fi. Restart both the printer and computer. Set the printer as default and clear any pending print jobs. Update or reinstall drivers from Canon’s official website. Running the printer troubleshooter can also help restore normal printing functions quickly. https://medium.com/@gracee0311/how-do-i-get-my-canon-printer-back-online-0631133c2d0a
