I posted this in October Brother bought a Printer/Scanner.
There doesn’t seem to be much movement on the Debian front for updating libsane.
The canon website has a program call scangear2 designed for use with the printer. It is available for Debian and Redhat. It takes about 10 seconds install using the script on a linux box that allows the script to run. https://www.canon.co.nz/printers/pixma-home-ts8260/support
Is anyone keen to convert it to a flatpak? I have read the flatpak documentation and was going to convert it myself but I am afraid it is gobbledegook to me.
