The quality of the 20# paper is just fine and meets all of my requirements for a printing need. I have tried others and my printer works best on this rating. I am pleased with my copies as opposed to other people's that are truly much thinner and flimsier. I purchase most of it to donate to our local school needy kids and their budget restricted teachers. I am thankful that Staples is able to offer this great deal for all of us consumers to be able to get it sometimes for free but often for mere pennies per hundreds of sheets of paper.
