Hi Myself Sam Diesel If your Canon printer is offline? Not to worry. The helpful methods in this tutorial can help you resolve this issue with ease. Click the power button to turn the printer on and make sure it is plugged in. A network connection should be established between the computer and the printer. Due to its distance from the access point or wireless network, the printer's signal strength is weak. The printer and wireless router may require a power cycle. This error could occur if the print job is directed to a printer that was unplugged from the PC.
