"According to one paper manufacturer... a cord of wood produces nearly 90,000 sheets of bond-quality paper or 2,700 copies of a 35-page newspaper."

Hence, one tree would produce about ~30 x 90 000 sheets of paper
SO DON'T WORRY ABOUT THE ENVIRONMENT MY SON. YOU GO GET THAT EDUCATION YOU DESERVE AND CHANGE THE WORLD
Edit: If we look at the average size of a tree @
http://www.ipst.gatech.edu/faculty/ragauskas_art/technical_reviews/Tree Size.pdf
We can more accurately count the number of sheets per tree using the previous source. So if a cord of wood 4ft x 4ft x 8ft produces 90 000 sheets, then the average tree of dimensions 1.5ft x 1.5ft x 70ft gives ~110742 sheets of paper per tree.
Edit 2: Further research has led me to discover that only certain trees have suitable fibres required for the processing of paper. These types of trees include spruce, pine, fir, larch, hemlock, eucalyptus, aspen and birch. Hence, I have adjusted my calculates to allow the average tree to have dimensions 2ft x2ft x90ft due to environmental regulations on tree harvesting as well as aforementioned tree types => ~253125 sheets of paper per tree. However, this number I'm assuming does not take into account the process of pulping required to separate wood fibres and manufacture paper. Mechanical pulping is about twice as efficient as chemical pulping but I am unsure of the source as they do not mention but nevertheless I think you are in the clear.
TLDR: You are all good to go OP! Print those papers!!!
