The Canon PRINT app cannot reach your printer over the network. The usual cause is the phone and printer being on different Wi-Fi networks or bands, or the printer being offline. Connecting both to the same 2.4GHz network and confirming the printer is on Wi-Fi resolves it.

Is the Cannot Communicate error serious?
Not usually. Codes at this level normally clear once the condition they describe is dealt with, and a printer that carries on working afterwards has nothing further wrong with it.

Switch off and unplug a printer before reaching inside it.
