Number 3 sounds like the biggest challenge to me.

Awkward and probably slow as you gathered.

Sounds even more complex to me.

Then you're lucky.

Probably. Maybe it is enough if you just derive a new class from
PDFRenderer and use that.

Difficult thing at any rate. I've just had a thought: What about the
Java printing API in JDK 1.4 in conjunction with the AWT renderer? I
think the printing API supports quite sophisticated printing attributes.
Never tried, though. And leaves out the PDF requirement except if you
don't care having slighty different output (not likely).
Seems like I was lucky only having to support PostScript printers. I
suggest you try out the GhostScript approach. If that doesn't work, try
to find a way to get rid of the non-PostScript requirement or give AWT a
Good luck anyway and keep me posted on your progress. I'm pretty
interested in your findings.
