I just noticed that gtk3 now defaults to depending on cups, and that this was recently added. This seems like a big change, and my impression was that we didn't generally do that, because there are a variety of approaches to printing in use. I don't remember discussion about it, but maybe I missed it. What do people think? Some people seem to think cups is necessary, and some people seem to hate it and banish it from their systems. (I don't really understand why a graphics toolkit needs to deal with printing, but I'm guessing there is some print widget included.)
