If you keep on facing Canon printer offline issue especially when you have a number of tasks lined up then this could really work you up. Before trying out any complex techniques to repair the canon printer offline status, you can try relinking the device to the Wi-Fi router.
Navigate to the settings and click on ‘Forget’ the connection before you add it back again later. Press and hold the printer’s Wi-Fi button until the light starts to blink. Once it is flashing blue insistently, go to the router and press its WPS button.
If this does not seem to help then you can restart the spooler service which is accountable for the printing jobs. If your canon printer is still in an offline state then all you need to do is contact us and we will take care of the rest with the best of our expertise.
