I have been using Staples tru Red copy paper for printing out documents, bills, letters, and charts from my computer or iPad. It works well for text and colored areas of a document in black and colored ink. The paper does not jam in my inkjet printer and is opaque enough to print documents clearly. Staples price is reasonable too.
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.
