A wireless Canon printer may go offline for several reasons. Firstly, if the printer and the computer are not connected to the same network, the printer may not be able to communicate with the computer. Additionally, if there are any issues with the printer's network connection, such as a weak signal or interference from other devices, the printer may go offline. Another common reason for a wireless Canon printer to go offline is a problem with the printer driver or software.
