I just found out about a new feature of the maps that many of the trails have.  These topo maps are being linked to a site that uses Google Maps and the myTopo.com topo maps.  They now have the ability to be printed from your browser easily!  In the past, the only way to print them was to make a screen capture, but now you can print simply by using the print function in your browser.  My limited testing shows it worked pretty well.
