Oh man, a friend of mine did exactly the same thing back in college, but using a tessel instead of a rpi: https://github.com/JRJurman/automated-ticket-printer https://github.com/JRJurman/automated-ticket-printer In action: https://www.youtube.com/watch?v=sOBhAbXNgUI https://www.youtube.com/watch?v=sOBhAbXNgUI IIRC, he actually used it on coop for awhile with a physical ticket spike to store completed tickets on.
