[Openicc] Gutenprint XML media settings written to live PPD

[edmund ronald]

Hi Guys,

 After making a proof of concept XML proto some time ago, Robert is now
moving towards making a beta-test version.
 The idea  is that media settings should be encoded in XML by Gutenprint on
one print pass, and then replayed at will later.
 We're thinking that a good place for a media-setting XML paragraph would
be in the live PPD for the printer.
 One advantage is that people can then trade their media settings, give
them to friends, just by copying the ppd and emailing it.
 The current CUPS interface already allows the user to point at a PPD from
the web interface.
 The current workflow, tools and user training are little disturbed.

 Is everybody happy with that?

 As for writing the settings, either Gutenprint does it directly, I guess,
or it dumps the XML in a temp file somewhere, eg in /tmp I guess.
 Any remarks on this from the distribution guys?

Edmund
