Hii my name is Luna Fallon i am from the technical team if you are facing a problem then you can visit our site. If your Canon printer is showing as offline, it means that it is not communicating with your computer. The first step to fixing the issue is to check whether the printer and computer are connected to same network. If the connection is stable, try restarting both the printer and the computer. If the issue continues, update it to the latest version. These troubleshooting steps can help bring your Canon printer back online and ready to print.
