Sometimes you need your students to have an entire sheet of paper to work on, but sometimes you really don't. One trick that I use is to print 2 or 4 pages to one sheet of paper.
I know every printer works differently, but here is how I use this feature on my EPSON WorkForce 3450.
I use this trick at least once a week in some way. It saves ink AND cuts down on the number of copies I use on my school copy quote. Score x 2. :)
