Are you asking where to go to put cash on your studentcard to use the printers? If so, Hux library, straight through the doors, on the left wall before the first computer room, swipe your studentcard, put in how much cash you want on your card, press the button, get your receipt, you can now print from the computers and photocopy. For the Auch library, in the main doors, straight to the left, (as in on the way to the law library) and in that little hallway thing outside the photocopy/print room. Same machine. I think there's another one in the AIC, but I've never had to use it, so I'm not positive.
