No, we can't.  As Jan explained, GTK+ requires that applications use
cairo for rendering, which we probably will not able to do even in the
GTK build, at least not easily.

Yes, but that still leaves unresolved the issue of how to set it up
correctly _after_ you know you need some setup.  There's not enough
information in ps-mule.el (or elsewhere in Emacs docs) to know what to
do, unless you have intimate knowledge of what your printer supports
and the fonts that are available.
