It's because of the frankly idiotic idea of persistent print queues. If you want to have this artifact that survives a user session, then the print subsystem needs super-user abilities.
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.
