Video of how easy it is to Airprint from an Apple device to a Canon MG5350 printer using your home wi-fi network. To print from iPhone/iPad required no additional apps. To scan to the iOS device download canons free app as shown in the video.
For me, as long as the printer and iOS device are connected to the same wifi network at the same time, mine prints and scans. This pdf link from Canon may help:

As mentioned, i use the Canon app on my iphone:

but others have said that this free app is not needed to print.
