National Geographic has built an easy to use web interface that allows anyone to quickly find any 7.5 minute topo in the continental U.S.A. for downloading and printing. Each topo has been pre-processed to print on a standard home, letter size printer. These are the same topos that were printed by USGS for decades on giant bus-sized presses but are now available in multi-page PDFs that can be printed just about anywhere.
