This is interesting, however to pour a bit of water on the opportunities here: - CUPS has existed for over 20 years - Java has existed for over 25 years However, I still not use CUPS or similar systems on Windows. And Java-based (or other VM-based) printer drivers have never been a thing AFAIK, on any platform. There are however platform independent device support at a lower level, e.g. OpenFirmware and EFI. This is usually not leveraged post-boot.
