Not good for double sided documents. The back side shows thru. Ink does NOT bleed thru...it just shows thru and makes the front side look messy. We have had minor problems with paper jambs or two sheets feeding together.
Rainy days usually meant paper clogged in the printer. The Staples' paper however didn't seem to know that -- it went through the printer as quickly as though the day were fine.
This paper says it is not recycled but it is porous and sucks up ink like crazy as is often typical of 'tired fiber' paper. If you think ink is too expensive you will use tons of it with this paper. I bought a case and the case is going back. The weight is not 20# in my opinion it is more like a 19# just enough to make an already skimpy weight way too thin. That it comes out of printer rippled from the heat attests to its skimpiness. I used cases of Xerox Multipurpose paper before and it had an excellent finish to it not absurdly absorbent and as they no longer make it tried Staples brand. My .02. Dont buy it. It's about $44 a case but costs far more because of its greed for ink.
