The HP Multipurpose Paper-500/sht/letter/8.5 x 11 is perfect for my printer (HP Office Jet Pro 8600 all in one). It works very well with the HP 8600--no paper jams and the weight of the paper is about right for my printing purposes.
Feeds just fine and prints great. Price is competitive with store bought paper and this is delievered direct to our house. HP has done a fine job with customer service.
This paper handles the inkjet (ie: water soluable) HP inks better than anything else I've seen. It looks beautiful, and has a nice "hand", ie: the feel of the paper in your hand. I print some well-saturated color graphics and although the paper can come out looking wrinkly when wet with areas of solid color, dark colors, etc., it dries fast and then becomes perfectly flat, like normal. I don't care that it costs more than the discount stuff. This is a high-quality product that consistently performs well. I would recommend this to any professional person who is unsure about whether to go with cheaper paper. Get this stuff instead. You won't be sorry.
