Using a tool called posterazor
http://posterazor.sourceforge.net/ you can make a big map out of the map Wooster posted with a regular A4 or A3 capable printer. I just did it, now I just have to glue all the pages together
EDIT: If you get a runtime error in the last stage try to resize the map a bit. Let's say like 10% off of the original then it should work.
