If you really want your printer to run right then you have to use quality paper. HP multipurpose paper is just that. Smooth, wrinkle free, and lint free.
I've used this paper for years and it does everything I need. I do question why you stopped selling the 5 ream packages. I understand not everyone wants to buy that much at a time, but for those of us that do, why not make that an option with a bit of a per ream price break??
