Yup, as I see it using cups-pk-helper gives two layers of auth, one for cupsd and another for policy-kit. Using cups-pk-helper as lpadmin or root would override cupsd permissions as it'll be running with all privileges, but there's still the policy-kit permissions.
Right now, I've tested it, with my patch, printer jobs can't be seen between users in gnome-control panel (I think it has nothing to do with my patch though). Jobs still can be seen in the "Additional Printer Settings", but when I try to delete the job, there, of an admin user from a non-admin user it asks me for the password of the admin user. Deleting the other way around works though (admin deleting non-admin jobs). Also, there's a gnome-extension named "Printers" which uses cupsd commands to delete jobs, etc. In that extension as admin, I can see non- admin jobs, and can delete them. On a non-admin account, I can't see admin jobs.
