Standard paper for basic usage. I run a lot of paper through my printers at home (one teenager a teacher and a computer programmer) so it is easier to buy paper this way. We use this for all kinds of printing and it works with no problems. Haven't had an issue with any of the reams so far and will continue to purchase my paper this way.
Staples 8 1/2" x 11" Copy Paper is a good product. The paper does not get stuck in the copier. The paper is not expensive and is a competitve price compared to other copier paper. I am pleased with it.
