Printing on the back of paper

As a junior in high school, there are many assignments for me to complete. While most teachers want assignments typed, there's no reason for an assignment to only cover one side of a piece of paper. Paper has two sides for a reason. USE BOTH. After printing out a sheet, put it back into the printer with the type facing up and print on both sides of the sheet. This decreases waste by decreasing the amount of paper that you use.
