I've several test installations on an old laptop, one is Mint 20.2 Xfce.
While adding a printer to the system I noticed there is no 'Unlock'
button on system-config-printer (Menu >> System >> Printers) as
found on other versions of Mint; basically the initial printer setup
is done without prompting for elevated privileges. The outcome of
that is if one needs to tweak something, say the printer driver used,
system-config-printer hangs. It is of course possible to tweak things
via the CUPS web interface (localhost:631) but for novice users this
will likely be a frustrating experience.

I'm wondering if there is some work-around or fix to allow for elevated
privileges to be granted within system-config-printer?

See if this discussion will help:

Center -> Printers (system-config-printer) UNLOCK switch permissions

It seems it is related to /usr/share/polkit-1/actions

Yeah pretty similar, though the poster actually wants to eliminate the
elevated permissions requirement. I wasn't looking forward to trying to
tweak the system's PolKit settings and opted for a kludgy workaround:

1) create small script under /usr/local/bin/:

#!/bin/bash
export SUDO_ASKPASS=/usr/libexec/seahorse/ssh-askpass
sudo -AE system-config-printer

..and set proper permissions:

% sudo chmod 755 /usr/local/bin/tweak-printers

2) edit command run for Menu >> System > Printers via menulibre(1):

"/usr/local/bin/tweak-printers #system-config-printers"

..click 'Save' and close MenuLibre.

This prompts for the user's password to run system-config-printers with
elevated privileges needed for adjusting printer properties and perhaps
more immune to future system changes than tweaks to PolKit.
