I'm all for printing out lecture notes so that you can add additional notes to the side, and also so your eyes don't burn out of your skull from staring at a computer screen for too long... but haven't people heard of double fucking sided printing??!1 And whatever happened to shrinking the size of pages so that you could fit two on one page? It's easier to compare equations that way anyway.
For FUCK'S sake.
Leave some paper for other people.
