My initial response to your earlier message was: Probably print-convert
needs to recognize a property that gives you more control over the
conversion, much like `prop:custom-write' gives you control over
`write' and `display' output.

So, that was probably the right answer after all, since the limited
property that's already available doesn't work well enough.

I can add that property. Meanwhile, I don't have an answer that works
with the current version.
