Free printing at college?
Most, if not all, universities and colleges charge for printing. And it can add up over four years if you only go for your undergraduate degree. This poster notes that you should try plugging in your laptop directly to the printer and it will print for free.
This hack is probably something the university would catch onto but it could be sweet while it lasts. College students typically aren’t rolling in money at this point in their life, so every tiny bit helps. It seems like a great idea for bypassing one of the greatest expenses of higher education. What a great hack!
