Actually it's pretty common nowadays to have printers on an isolated VLAN. The only way "onto" that network is through a central printing management server that handles billing/accounting and job release duties. You see it often in Universities, but also in larger businesses where you want to stop someone from accidentally printing 5000 copies instead of 50, or having print jobs stack up on top of each other in the output tray (think HR/sensitive information being scooped up by accident.)
