We use Staples copy paper in our MFC machine for correspondence copies reports whatever our printing needs are. Its a good performing product that is very economical.
The Staples paper in the plastic wrapper is horrible! It curls when printing and it very hard to manage. This paper in the red paper wrapper is perfect and I pay a little extra when I need to.
Since the schools have no money supplies are limited. Thank goodness for the good deals on paper from Staples. It is very convenient to have my own stash of paper available for the children and myself to use.
