Unfortunately this is a very misleading post. I don't doubt the end result - it's useful that it works, but it's not "natively" and, unlike what some people assume, Claude didn't write a driver. It basically used HP's existing proprietary driver in a Linux VM on macOS, and just bridged that to macOS.

It also requires a root launcher that runs code from the user ~/.hp1008 dir, so security is weakened.
