I used several types of paper. The Staples Multipurpose paper is great for professional documentation. Don't use this paper for resumes photos or other more impressive print jobs.
I've been buying boxes of paper for our church when there have been special coupon offers. It really helps when you're donating items to a non-profit organization like a church group.
I need this kind of paper for school projects (assignments and the like for students). Good value versatile and the price isn't bad either (I used the BOGO Coupon!)
