Why is my iPad not connecting to my Canon printer?
Ensure both the iPad and printer are on the same network with the same frequency. Refresh the iPad’s Wi-Fi connection. This procedure forces the iPad to look for the printer again. To refresh Wi-Fi, open the iPad’s settings, tap Wi-Fi in the left-side list, and tap the green switch to turn Wi-Fi off.
Why is my iPad not detecting my printer?
Make sure your printer has paper, and enough ink or toner installed. Make sure your printer is connected to the same Wi-Fi network as your iOS device. Make sure your printer has power and is turned on. Try turning your printer off and then back on again to see if it resolves your issue.
