School Printer Attack

My school's computer network is set up so that you can print to any printer in the school from any computer. So I made a document in Word that was about 70 pages of blank paper, and I printed it to a bunch of random printers in my school's network.

I'm an environmentalist, I would feel extremely guilty if I wasted that much paper and ink, so I leave all the pages blank so that they can be used again. I'm sure I still piss a lot of teachers and staff off though.
