My wife and I have homeschooled our now 5 children for over nine years and use a lot of school/office type supplies on a daily basis. The Staples brand copy paper has the look feel and performance of more expensive paper brands but at a significant discount. We've never had an issue with poor feeding even when our children use the Lexmark Pro Series all-in-one printer/copier/fax machine to make copies for their tests quizzes and daily assignments. We have noticed that some of the other more expensive brands actually do cause jamming frequently so this will continue to be in our school's inventory.
I have tried many brands of copy paper and this one is by far the best. It works great in all temps. Especially humidity. The paper never sticks together
