Blank map of US counties
All 3141 counties, unlabeled and unfilled. The SVG prints at any size without going fuzzy and opens in any editor. It comes out wider than it is tall, so it prints sideways.
What you are printing
Alaska and Hawaii are moved in below the mainland to fit on one sheet, and Alaska is drawn at about a third of its real size. Everywhere else on this map sits where it is.
Every county is a separate shape, so a vector editor can select and fill one without touching the ones around it. Names are in the file as titles rather than as drawn text, which is what keeps the printed sheet blank.
Every county on it
The map page lists all 3141 counties by name, and colors them in the browser if you would rather not print anything.
