Great!-) instable Haskell programs are always somewhat embarrasing,
even if one can blame external sources.

perhaps I'm misunderstanding something here. It's been a while since
I looked into this, but when I wanted a way to convert the graphs I
draw on wxWidgets to print in scalable form, the way to go seemed to 
be to create a Postscript context and pass that to the normal repaint 
function, so that it would draw in Postscript commands instead of on
the screen. Seemed almost too easy, only that I couldn't find a way to 
create such things in wxHaskell.

I don't have a Postscript printer, I just want the eps in vector form, not 
bitmap, for embedding in papers and the like. How does the printer 
support you're talking about work, then?
