In the past, whenever I've wanted graph paper I've always written a simple program to draw horizontal and vertical lines to form the grid size I sought, then printed out the results. I was thinking about adding a little web app to jlion.com to do this as a public service, then found this site: http://incompetech.com/graphpaper/plain/. This guy has done a wonderful job and his web apps are much more comprehensive then mine would be.
