I'm not wasting money on printing
I will always print on cheap laser printers and I print in tiles. I refuse to spend $30 for one sheet of ink jet paper for my assignments. I don't care if it gives me a better grade. I'll won't print HUGE prints for $30 for just one sheet. I do it in tiles (sticking together small pages) and the professors can lower my grade, I don't care, as long as I pass. I'm not wasting my money just for some school project to boost my grade. I focus on the quality of my design, not printing on an expensive printer.
