I am reopening this bug as users-admin currently lets every new desktop user get added to the lpadmin group, so every "real" (human) user on a typical machine will be able to create and remove print queues or to kill anyone's print jobs. By default only users of the category "Administrator" should be added to the lpadmin group (have "Manage printers" active. For users of the "Desktop" category all privileges except "System administration" and "Manage printers" should be selected by default.
The patch to add lpadmin to the supported and listed groups/privileges seems to be OK.
