This is the worry. It seems like a really unnecessary privilege escalation.
ChromeOS does away with the whole idea. There are no persistent printer queues or jobs. Artifacts of the printing subsystem have lifetime tied to the user session.
Maybe it's a Gnome problem. KDE let's me see what I had previously printed if I want to see it, or reprint something.
I also know many people in pre-press who make good use of that.
