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.
This brand paper is always the best choice for the reports I print off on a reguklar basis. I wouldn't buy any other kind. Unfortunately I do not have the occassion to use much paper at the office.
Purchased because I was looking for inexpensive paper for general printing purposes. This met my needs. I didn't need high quality printing paper and the price was right.
