Many consumer printers today can display images with a higher resolution than the ones in the current test page, so it'd be good to improve those. Also, I spoke to someone who is familiar with print and they mentioned solid rgbcmyk blocks are more useful than the 'color wheel'. I could imagine further improvements (maybe adding a 'rainbow gradient', text in various point sizes, 'hyperbolic wedges'), but this seemed like a good first step.

The upstream CUPS test page is terrible: it includes images that are way lower-quality than today's consumer printers, both in terms of resolution and colour depth. Upstream [doesn't seem interested](OpenPrinting/libcupsfilters#100) in improving this. The next best thing is to at least have a slightly-better test page in Nix, and take the opportunity to throw in a Nix logo or two. I spoke to someone who is familiar with print and they mentioned solid rgbcmyk blocks are more useful than the 'color wheel'. I could imagine further improvements (maybe adding a 'rainbow gradient', text in various point sizes, 'hyperbolic wedges'), but this seems like a good first step.
