Look folks... there are now only a few cut sheet paper manufacturers (copy paper) in the USA. The Staples brand Red Box 20lb letter size paper is the EXACT SAME paper weight feel performance and quality as the paper that you pay far more for like the HAMMERMILL XEROX H-P or KODAK labels.... exactly the same... no difference. The only thing that has to be changed is the wrapper of each ream packaging that's in the carton of ten reams...that's it! If you're having trouble with paper jamming or curling it's most likely the moisture content in the air or in your storage area. NEVER store paper on a concrete floor including that covered with tile or low-pile carpet. Keep it on a shelf at room temperature prior to using it in your printer/copier and you'll be home free.
This paper works well for my printers at work and I have also used this product at home. The price cannot be beat and I am glad to know that the product is not compromised by the price.
