We order this paper all the time. The last order of 4 cases came in with some of the reams a lighter weight than advertised. This was not 20 pound paper. It kept jamming our copy machine and running multiple sheets through our fax. I am willing to try it again but will be very thorough with checking the weight of it.
I use this paper for everything. I use it in my copy machine my printer and my fax machine. It works well in each of those applications just like the descrpition states on the Staples website. I always buy this paper unless I have a coupon for a different copy paper.
