I've been using Hammermill paper for years with zero issues. Tried this economical brand and have regretted it. When printing a couple pages at a time, it seems fine. But, if I print a large stack (20+ pages), I will get blank sheets mixed throughout the print job. I had hoped it was a fluke with one ream, but I'm into the second ream and it's still doing it. I'll be trying to see if I can return the remaining reams as this is totally worthless to me.
This type of paper is very Good. It does not stick together while Copying and is very Smooth. I find that this paper is Better than Most. Some Copying Paper appears to be a Little too thick and can get stuck in the printer. This Type of Paper does not give me this Type Problem.
