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. > If some of the characters in the region you print don't have a > corresponding entry in ps-mule-font-info-database, it says something > vague about "some characters will not be printed". > > We could turn that into a query or an error. 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.
