I have used Staples twenty-pound paper for many years. It feeds well through the printer. It rarely jams and when it does jam on occasion it is usually my fault. However the paper is strong enough to enable me to quickly pull it out of my printer without the problem of its shredding. I have used Staples twenty-poiund paper for at least the last ten years (and probably many more). I have yet to find any yellowing or other signs of deterioration in any of my files. I have also not found any smearing of the ink applied by my printer to the paper. I have also used higher quality papers for various purposes and do not find that their greater expense whether quality-wise or weight-wise results in any significant improvement in performance reliability or appearance.
Have had no jams with this paper in my HP Laserjet printer unlike my experience with Hammermill Copy Plus which jammed frequently. Paper also is a little heavier than Hammermill. Will consider the purchase of an entire case of this paper
