I think this paper is actually better than the hammermill copy paper. It hasn't jammed when I have printed with these and I do bigger print jobs. I would buy this more if it wasn't more expensive.
Good paper, I had no problems with it, other than the fact that it was $32. Too expensive, and for some reason this was the ONLY 11x17 paper available within 20 miles of me.
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.
