Don't bother listing CUPS here; we will only be using
/usr/share/cups/model for PPD files supplied with CUPS.

What kind of printer drivers are to be supported by this?  I don't

FWIW, device ID information is not standardized in IPP, at least not
yet.  Some vendors put the device ID string in printer-info, but that
gets truncated too easily.

-1 from me on that one, we've seen too many problems over the years,
and you really only need Foomatic to support legacy Ghostscript
