I look at the source code and other applications using gnome-print. If
you miss something there, just ask.

Do you need the gnome-print-dialog for that?

I've fixed some issues related to transparency a couple of months ago.
I'd try the latest version.

Not yet. gedit needs one, but as it probably involves changing the
