There can be several reasons why a Canon wireless printer goes offline, including connectivity issues, printer driver problems, or paper jams. Poor network connection or interference from other devices can cause the printer to lose its connection to the network, resulting in an offline status. Another common cause is outdated or corrupt printer drivers, which can lead to communication issues between the printer and computer. Additionally, paper jams or other mechanical issues can cause the printer to go offline. https://printersofflines.com/canon-printer-offline/
