I have purchased cases of Staples 20 lb. multipurpose paper for over 20 years. The copies always come out clear and is appropriate even for formal business letters. I find that the color inks print so nicely on this paper which provides a greater contrast. We have lots of humidity in the area where I live and I have never had a problem with my paper jamming or not working in this condition. Another plus is the price of this product. A very fair price and often Staples offer wonderful price cuts.
With an ink jet printed and a family of 6 we seem to go through paper as quickly as we go through ink. When this deal came along (a case of paper with a rebate) we jumped on it. We're not paper specialists but we can say that we sure notice a difference in the quality of this paper compared to the reams of paper we typically grab at W*lm*rt. The paper is certainly brighter and smoother. We don't notice any additional ink lines surrounding the printed letters (almost as though it runs a bit) when we print our documents.
This Multipurpose paper is a great value for the price. It is brighter then other paper I have used. I am going to continue to use it. I would recommend it. It works great in my All in one printer.
