The IFHP filter supports pdf to PostScript conversion by using the
GhostScript program. Unfortunately for me, the GhostScript developers
are too clever. By default, PDF files need to be 'seekable', so they
put a restriction in that they require input from a 'true file'.
I have finally figured a way to pass the name of the input file
to the GhostScript program so that PDF conversion works correctly.
By convention, LPRng passes the input file path as:
... ifhp -eFileName
The \%s{inputfile} token will expand to the value of the -e option,
otherwise to /dev/fd/0 if the /dev/fd facility is available,
otherwise to '-'. This means you can now do:
pd2ps_converter = gs .... -c save pop -f \%s{inputfile}
and you get the name of input file, GhostScript will open the file,
and there will be PDF to PostScript conversion. I hope...
