Ummm.... Printing for a normal mass market paperback is in the 1000dpi range, newsprint may be a bit lower (depending on the newspaper). Ordinary laser printers that you buy for a few hundred dollars US are 1200 dpi. Fancy glossy magazines, high-end text-books, art books, and the like are often printed at 3000-4000 dpi. Nothing much is printed past 4Kdpi, as you start needing a loupe to tell the difference.
Reflectivity and contrast, on the other hand appear to be spec'd differently for paper than for electronics. I have no idea how to compare those numbers.
