[Bug 1883370] [NEW] system-config-printer hangs when trying to change driver

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Ubuntu Foundations Team Bug Bot (crichton):

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.
