Ahha, that makes more sense. Sorry, I didn't understand your original post.

That's two different things. But I suppose it should convert to something
printer(-driver)-digestible (i.e. PostScript).
Out of pure curiosity, have you tried to install "Print services for unix"?
Might not be available in your Windows version, though. Comes with Pro and
up. Also have a catch of not accepting localhost connections, even though it
listening on 0.0.0.0.

I don't know, sorry, have not printed anything from Cygwin.

Well, at least, now we know that iPhone email client properly insert threading
headers :D
