Enhancing the existing foomatic tools to get this information seems like
the best route, since they already advocate that people submit similar
info for foomatic.

Attached is a printer XML file from foomatic.

The purpose of foomatic is to generate PPDs for printers based on
information in its database.  Most distributions generate the PPDs ahead
of time and ship only the PPDs with the distro (SUSE for example puts
them all in /usr/share/cups/model).  The majority of people configure
their printers through one of these.

In some cases people may use a PPD that isn't from foomatic.  These are
downloaded from the vendor or come on a CD with the printer or whatever,
and aren't apart of any database.  In general I'm not sure how you would
fit those into a hardware database.

Makes sense, I think.  You should talk to the foomatic folks and see if
you can get some buy in to the idea.  At the very least, the foomatic DB
is a good starting point for your own printer database.

    Does not understand PCL as most other DeskJets, it uses the
