Topographic Wallpaper

Export a JPEG from TOPO! It seems to have a problem if you try to export the entire state, but you can split it up into fairly big chunks.

Download GIMP

Choose Image > Guides > New Guide By %.

This splits up the photo for printing, and you can break up your photo into A4, easy-to-print sizes.

Finally, use Image > Transform > Guillotine.
