The paper gets stuck in printers on a mild humid day. It seems to absorb the moisture in the air and swells just enough to jam the paper path. We never had this problem in the winter but it is really a problem in our 3 printers now that the summer has started.
I like the quality and affordability of the paper we buy for our home printers and fax machine. I never have any problems with paper jams when I use the Staples paper!
