I have been using 24 pound paper in my printers and find it feeds much more reliably than 20 pound paper. And gives your printed documents a better "feel"
This paper is pretty expensive and printer ink tends to smear a bit for longer than on generic printer/copy paper. However it does make everything that is printed on it look sharper and more professional.
The Staples Premium 8 1/2 X 11 Ink Jet and Laser Paper 24 lbs. 98 Bright is top of the line. A little pricey but very quality paper. I do not really need that quality of paper but I buy it because of its quality.
