Steve: Apologies for leaving your name out of what I wrote earlier.
Your work (and hopefully that of David Pilling) will be important
for as near as we can expect of a full answer to the problem.

I'm not entirely sure why. My contribution to solving The Problem has
so far been zero, and will very likely remain so.

I hope this will not be the case. ;-)

I was thinking more in terms of the work to the PS drivers and GhostScript
itself, where I can see my contributions being somewhat limited...

I suppose John was referring to PrintPDF, which, with a few changes,
could become a valuable contribution to the publishing toolchain. This
mainly concerns the "Optimization" options. Currently, PrintPDF offers
the four optimization options that are predefined by Ghostscript (which
are in turn based on Adobe Distiller). Of course, that was a perfectly
obvious choice for you to make. However, neither of these options is
really suitable for generating publishing quality output and I usually
use !ps2pdf when I require high quality because that gives better
control over the treatment of embedded bitmaps.

You need to upgrade... ;-)

Version 0.50 has full (I think; I'm happy to be corrected if it doesn't)
control over the optimization options that GhostScript offers, in a
similar form to that used by ps2pdf. This is in addition to the original
four options (and the new EBook option in version 0.50), which I agree are
not particularly useful in reality. The main difference with ps2pdf now
is that I've removed options that the GS documentation states are
unsupported, or which just map to other options.

Details (as ever) at http://www.stevefryatt.org.uk/software/printpdf/

So, when the time has come I would like to discuss a few improvements
with you that would allow higher quality profiles to be defined for
PrintPDF. Of course, all of that could be done using the Ghostscript
command line but most users would not want to use that.

I would be happy to update it further if required. The custom
optimization options required a full re-write of the GhostScript
command-line support in PrintPDF, so further improvements in that area
should be a lot easier now than they would have been six months ago.
