Check out this fun freebie from National Geographic! Print your own free USGS PDF Topographical quad maps! These are the same quads 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! Just Zoom into your area of interest or use the search box to look for a Quad. Red pointers will appear at the center of each USGS 7.5 minute quad, click on the pointer to download the multi-page PDF. I was able to search for my location and find it easily!
