SMC uses a printing queue system. Whenever you "print" a document, picture, etc from your device, it is sent to your print queue. When you swipe your Knightcard at a printer, you can release your print jobs from your queue right then and there, regardless of which printer you use on campus! On SMC computers this printing queue maps automatically. For personal devices, a program called "Papercut" is needed to send the print jobs to your queue.
