Blank map of Europe
All 52 countries, 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
A conic projection centered on Europe, so the countries keep their shapes instead of leaning the way they do on a world map.
Every country 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 country on it
The map page lists all 52 countries by name, and colors them in the browser if you would rather not print anything.
