re: printing Grid lines
While the default color is on the light side when printed, I found "0, 27, 255" for the Major color and Med. Turquoise "112, 219, 219" for the Minor color came out nicely on my little HP. It looked like regular graph paper to me when printed, though it is a bit much on screen.
