Neat, but it takes two pages on printing in the landscape orientation in Firefox on either A4 or US letter paper sizes here, with minimal font size set to 16. Generally matching of text dimensions to container dimensions is unreliable if you take into account browser settings (not just minimal font size, but also things like differing fonts and disabled custom fonts), and perhaps an SVG image with pre-rendered texts would be more appropriate for such a task. Or even a more pages-oriented format, and for different paper sizes.
