I have used nothing but Staples brand Multipurpose paper for many years. It is reasonably priced and has always worked for anything I've used it for. I am a realtor and I make fact sheets for listings print out showing sheets for buyers and send letters both business and personal. This paper does well in all of these regards.
I've purchased this paper in the past and could not pass up the opportunity to buy ot for $1 per ream after discount and rebate. It is very good for general use - copies reports and all other day-to-day printng needs. The colorlock aspect makes it work better than some other general purpose papers with dye-based inkjet printers. While it is not suitable for high quality photo printing it is more than adequate for printing web sites and other color graphic pages that are primarily for temporary use.
