Hello I am Angilina Ken. Encountering the frustrating Canon printer offline wireless error? Don't fret, troubleshooting can help you regain online status and resume wireless printing. Begin by checking the printer's wireless connection and ensuring it is properly connected to the network. Verify that the Wi-Fi signal is strong and stable. Restarting the printer and the router can often resolve temporary connectivity issues. Updating the printer firmware and drivers to the latest versions is also crucial.
