Whenever your Canon Printer Is Offline, you are always recommended to immediately check your printer’s power cable. Make sure the cable is tightly plugged into an electric outlet otherwise your printer can throw an offline error message. You should also restart your router as the printer can go offline due to network failure. If your printer shows offline status yet, then this time you should confirm that the “Use Printer Offline” feature is not enabled. Make it disable first by clicking on the check-box just behind this option. Thereafter, cancel your unfinished print jobs if anyone is available. Now, you can select the document on your connected PC and give a command to the printer to print. You will now be able to obtain quality printouts without any error issues.
