The Printer Is Not Detected

Check the following:
Is Canon Print Service enabled in the printing settings of your terminal? (→"Activating the Service")
Does the device you are using support Canon Print Service? (→ "About Supported Printers and Multi-function Devices")
Network settings of the Canon device:
Is <SNMPv1> set to [On]?
Is the LPR port set correctly?
Is the gateway address set correctly?
Is the subnet mask set correctly?
Are the Wi-Fi settings enabled on your terminal?
Do the wireless LAN network that the terminal is connected to and the network that the Canon device is connected to match?
If the printer is not detected even after you have confirmed the above, disable the Wi-Fi settings of your terminal, then reconnect and try printing.
Alternatively, enter the IP address of the device to manually discover the device. (→ "Discovering a Device by Specifying Its IP Address")
