This was particularly difficult to handle +for the case of fonts with the result that only a selected +number of application could offer WYSIWYG under Unix. Equally, +wxWidgets offered its own printing implementation using PostScript +which never really matched the screen display. + +Starting with version 2.8.X, the GNOME project provides printing +support through the libgnomeprint and libgnomeprintui libraries +by which especially the font problem is mostly solved. Beginning +with version 2.5.4, the GTK+ port of wxWidgets can make use of +these libraries if wxWidgets is configured accordingly and if the +libraries are present. You need to configure wxWidgets with the +{\it configure --with-gnomeprint} switch and you application will +then search for the GNOME print libraries at runtime. If they +are found, printing will be done through these, otherwise the +application will fall back to the old PostScript printing code. +Note that the application will not require the GNOME print libraries +to be installed in order to run (there will be no dependency on +these libraries). + +It is expected that the printing code that is currently implemented +in the GNOME print libraries will be moved into GTK+ later. +
