Comment 33 for bug 24689

I have just tried the Gtk Print API in gtk+2.10.
It is quite simple and cool. An example can be found here.
http://cvs.gnome.org/viewcvs/gtk%2B/tests/print-editor.c?view=markup
There are two ways to impletement this in mozilla.
1. Just use the GTK Print API dialog part.
http://developer.gnome.org/doc/API/2.0/gtk/GtkPrintUnixDialog.html
It's maybe simple to do. But I don't think it is a right way.
2. Use the GTK Print high level API
http://developer.gnome.org/doc/API/2.0/gtk/gtk-High-level-Printing-API.html
It may be need a big change in mozilla.
