Okay. It is paper. It works well for printing and copying on an ink jet (only kind I have). Doesn't work well if you want to print quality pictures but you knew that right?
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.
