Used dozens if not hundreds of these reams by now and never had a paper-caused problem yet. No jams or feed issues in multiple printers - which doesn't sound like a big deal and shouldn't be - until it is. Boringly reliable so I stock up whenever they're on sale.
This package contains plain white paper which is indeed white and flat and blank. The paper seems to accept and display ink and toner of various types and colors. I cannot think of another 100 characters worth of comments to say about a package of plain white paper. Don't you just love automatic electronic product surveys? I hope that this comment will help you with your next purchase.
