Chris,

Thanks for sharing more details about how things work in the CIDFont
department. My understanding grows, but I guess I still need to learn a
lot, at least to the level of detail needed to create the application I
have in mind :-)

Till,

I consulted your earlier post on the subject at
https://bugs.launchpad.net/ubuntu/+source/cups-
pdf/+bug/820820/comments/12 and implemented your suggestion for the PPD
file. Indeed the cupFilters "application/vnd.cups-postscript 100 -" and
"application/vnd.cups-pdf 0 -" do the job! Now, in my CUPS backend I
read the environment variables FINAL_CONTENT_TYPE and CONTENT_TYPE to
decide if the stdin stream is PDF or PostScript, and act accordingly.
This approach produces searchable PDFs in both cases! So my issue is
solved now.

Next thing I want to do is study the PPD syntax to create a tailored PPD
definition for my application. There is plenty of documentation for
that, but possibly some issues will arise again. Of course this forum is
not the place to discuss CUPS and GhostScript related issues: where is
the place to be for that?
