My company uses Staples Multipurpose Paper 8 1/2" x 11" Case by the pallet and I also buy it to support the daycare that our children attended for several years. From my experience it is a superior quality paper. All the sheets of paper in the ream and/or case are identical and consistent (i.e. no pockets or patches of inferior quality sheets of paper within the ream or case). If there are paper jams in our printers are work it's usually because of the printer needing to be serviced not because of the paper. I would recommend Staples Multipurpose Paper to anyone and everyone.
