I've been using Staples Multipurpose paper for many years. I've always found it to be excellent. The brightness is equal to Hammermill or any other premium brand. Many house brands and lesser grade papers bring a lot of paper dust Staples Multipurpose does not. Your printer will not be able to detect any difference between this paper and the one you are using now (and paying twice as much for). In fact I would say that Staples' brand sticky notes envelopes and labels are also as good as or better than national brands.
The paper was of good quality and suited our needs exactly. When more paper is needed we will purchase again if price is consistent with other vendors.
