Hii,
If you are connected to the network, proceed as follows: Go to Home > Settings > Bluetooth & devices > Devices > More devices and printer settings > right-click on the TR4720 and click Remove device.
After restarting, download Canon (Print Driver and Scan Utility) Autorun and run the installer.

Although this is not a Microsoft website, it is the official [TR4720/CANON] site.
