will big sur OS work with Canon Pixma MG7520

Hi,

A Canon MG7520 is mentioned in About AirPrint - Apple Support as a printer supporting the driverless AirPrint technology. So, yes, this means that it should be possible to add your model as an AirPrint printer, without the need for a driver (when using a network connection).

Add a printer on Mac - Apple Support

Reset the Mac printing system to solve a problem - Apple Support

Canon UK has a guide (with somewhat different PIXMA models) that may be of interest to you:

https://www.canon.co.uk/support/consumer_products/apple_airprint_guide/#Pmac

I there,

Hope is not lost. Try these steps:

Go to System Preferences > Printers & Scanners > Select the printer > hit “-“ > hit “+” > select the printer > for “Use” use Generic Print Driver. See if this works.

Cheers,

Jack
