There are several places on the Internet where you can print parts of topo maps. Why have parts when you can have the whole thing. Might as well go directly to the source for the complete maps.
Step 1: USGS Web Page
Point your browser at store.usgs.gov.
Once you get the page loaded, click on the "Map Locator" link near the upper left corner.
Step 2: Enter Location
Let's enter in the location directly. Use my favorite hiking spot.
Dolly Sods in West Virginia.
Be sure to click on "Mark Points" radio button.
Step 3: Download Maps
After you enter a location the center of the page will look like below.
The black lines mark the "map footprints" which is the edges of the 1:24,000 scale (AKA 7.5 Minute series) USGS topographic quadrangle maps. This can be changed with the drop-down menu on the right. The black text with yellow highlight is the name of that particular map. In this case it's "Blackbird Knob".
If you entered a location it should be represented on the map by a red colored inverted teardrop shaped marker.
Left click on the red marker and you will see a pop-up that shows all the topo maps that are available for that area.
In this case there are four maps listed. Two different 7.5 Minute maps. One updated in 1982 and the other last updated on 1998.
The Kingwood 30 minute by 60 minute (1:1000,000 scale metric) quadrangle map last revised in 1981 and the Cumberland 1x2 degree (1:250,000 scale) map.
Click on the download link next to which map you'd like a copy of. The map image you receive might not be exactly centered. I guess it was someone's job to take every USGS topo map and feed them to a scanner. That person must of had their off days because some maps are better centered than others.
