Dear Maintainer, Recently, I spent hours to understand why other users can't access to system-config-printer. So, I will be very greatful if you could use Ubuntu solution (https://bugs.launchpad.net/ubuntu/+source/cups-pk-helper/+bug/934291 ), which may not be perfect but it fix a problem open in 2013 that has not found an upstream solution since.
Thanks, Best regards.
