I have been using Staples store-brand paper for more than ten years now except when I find another brand on sale somewhere else. I have never had problems with their paper. Very seldom jams. Print quality is good but that has as much to do with the quality of the toner too.
Needed to stock up on copy paper and this sale came at a very good time. Have used Staples paper for years and have been very happy with it. The delivery time was faster than expected and the overall service was excellent.
