I did this out of pure convenience, and actually never experienced the university's Windows account system at all (would I have had to sign up for an account? who knows). I had a list of strategically-located printers in my printcap, chose one on the way to whatever class I was headed to, kicked off the print job, and collected it as I passed by to class. In class I would get the previous week's assignment back, take the staple out with my pocket knife, and reuse it to staple the current week's homework before turning it in.
