system-config-printer hangs when trying to change driver

[Bryan Walsh]

gnome-control-center is able to find and install my network printer (Samsung M287x) automatically. When I attempt to change the printer driver (default printer driver doesn't support duplex printing) via system-config-printer, system-config-printer will hang. Please see attached log captured via system-config-printer --debug. I am running stock Ubuntu 20.04. Changing the driver worked fine in ubuntu 19.10.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug also affect my Linux Mint 20 install. I left the dialog for like 10 minutes, but it does not give control back to the user, it's just frozen. Is there a workaround available for this problem?

Addendum to the above message: I'm trying to change the driver of a Canon printer.

[Bryan Walsh (yetanotherbryan)]

I was able to change the driver directly through gnome-control-center dialog vs the system-control-printer dialog. Not sure if you have this option under Linux Mint or not, but this is what I did:
 Open gnome control center, go to printers and select the printer of interest, click the gear icon and click on "Printer Details".

[Bas (beaver-ui)]

That worked, thanks!
