GhostScript actually does exactly that, converts a .ps into a .pdf file, and somewhere in its documents I thing it does say that PDF is sort of a compiled .ps - but then it's been a couple of year since I played with that, so I'm not sure I could find that again.

I'll defer to you, but isn't Ghostscript a converter that happens to require a PS printer driver to create a file as a first step?

Ghostscript could probably have been written to take HP-PCL or Kyocera Prescribe as input formats, too.

I don't think PS is a requirement for PDF. For Ghostscript, sure. But not for PDF.
