Thanks for the reply.

The file format is not important as long as its large and I can print it (on a large sheet of paper or on multiple 8.5 x 11 I have to put together). I honestly don't know much about the various file formats anyway to make a rational choice. Also its not my map, its a map someone else uses for a home campaign involving the Temple of Elemental Evil and the surrounding area. I just thought it was very good as far as distances and placement and cannot find anything like it on the web. I have the original module and the map that comes with it is very basic and not very useful.

It does not have to be too fancy at all since its just for my upcoming AD&D game I am going to run for my group over the next year.

I like both of the below styles but they are pretty fancy and might be too much.
