If your my canon printer is offline then the first thing that you must do is seeing whether it has been set as default or not. If there are several printers that are connected to your laptop and some other printer is set as default then it is pretty obvious that the canon printer will appear to be offline even if it is online.
There is nothing to worry about as you can simply go to the control panel and set canon printer as default and then try to print. If this doesn’t solve your problem then you can contact us and we will help you out.
