If the questions are directed towards my maps, I have done the majority of the work for people confused about how to print the maps to scale. Believe it or not I am one of those folks.

So, when I make the maps (Thunderspire, Pyramid of Shadows and now Trollhaunt), I am making the maps and then I save them at scale. In other words, if the map is to be 12 inches by 10 inches, then I take the map into photoshop and make the image size 12 inches by 10 inches, thus a person only needs to print at 100% to make the map usable for minis.
