I can switch to using /usr/share/ppd/gutenprint at any time. I would
rather have the CUPS ppd symlink in place before making the change
(/usr/share/cups/model/ppd -> /usr/share/ppd).
I'm still not sure that the Gutenprint PPDs are "generic" PPDs:
- They only work with the CUPS spooler, because they contain special
magic:
*cupsVersion: 1.1
*cupsModelNumber: "0"
*cupsManualCopies: True
*cupsFilter: "application/vnd.cups-raster 100 rastertogutenprint.5.0"
*cupsFilter: "application/vnd.cups-command 33 commandtoepson"
A PPD is, by definition, a definition for a PostScript printer, but
these PPDs are merely a "bridge" between CUPS and the libgutenprint
filter, rastertogutenprint. Without the magic, they are useless.
Are they really suitable for inclusion?
Note that with CUPS 1.2, we will not provide any PPDs at all. We
provide a small generator program, and the CUPS daemon can generate
them on the fly. Admin tools will then have to do this all through
CUPS, which AFAICT they can do now if they wish.
- While admin tools legitimately need to access them, they will always
be CUPS-specific. Should CUPS-specific admin tools use only the
generic location, or would looking under /usr/share/cups/model
(which will also include the generic PPDs) be better?

Roger
