Worth having a look here (http://gimp-print.sourceforge.net/), I didn't find a driver, but you may be luckierThe printer is Canon MG5220 and support was dropped when Catalina was launched and there is no plan to update the drivers.
I am finding it difficult to find generic drivers online.
There is no ethernet port on this printer so I will try the USB connection to Airport Time Capsule and wifi.
I may have to set up the printer for network printing so will have a look at this later tonight.
On direct (usb) to Mac it will print Jpeg but only outlines in documents. Text is missing.
