Nice. It seems there is a systematic error towards the edges of the paper, which can easily be fixed in software. Though it would be nice to do more tests. For example, there is some error when drawing sharp corners. It would be instructive to see how that changes as you change the angle, etc. And how that changes based on location on the paper.
