Ok, the gnome print API is modeled after Postscript. So I suggest that
you find a good postscript reference on how to use them. So if you have
in postcript the following commands to draw a rectangle :

100 100 moveto
100 300 lineto
200 300 lineto
200 100 lineto
closepath
stroke
show

You will use in gnome-print :

pc = gnome_print_context_new ();
gnome_print_moveto (pc, 100, 100);
gnome_print_lineto (pc, 100, 300);
gnome_print_lineto (pc, 200, 300);
gnome_print_lineto (pc, 200, 100);
gnome_print_closepath (pc);
gnome_print_stroke (pc);
gnome_print_show (pc);

etc ..

There are a lot of unix aps that generate postscript code for printing
output that is one of the reasons the API is based on postscript. I
started some time ago writing a small gnome-print tutorial but i have
not had the time to work on it. This has been requested a lot but nobody
has done it yet.
