Kudos on the new Library Module! Here's an idea I'd love to see integrated:
We currently use a web-based print management software (PaperCut www.papercut.com). This program allows us to "load" the student's account with a predetermined amount of money that gets used up as they print to a network printer in the Library (i.e. $10 at the beginning of the semester and $.10 a page). When the money runs out, the system does not allow the student to print until they reload their account by purchasing more printing credits.
Currently, students could go to the bookstore and purchase the additional credit, then we fullfill the order by logging on to papercut and adding the credit on their account.
Tying all this together would be splendid!
