Blank map of Indonesia
All 33 provinces, 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
Mercator, which stretches land the further it sits from the equator. This map straddles the equator, which is where it stretches least.
Every province 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 province on it
The map page lists all 33 provinces by name, and colors them in the browser if you would rather not print anything.
