I have no time currently, so please do it.
just of the top of my head (I'll have a deeper look at the code later
this week and get back to you with a better answer) , for the gl2ps
stuff, I think you should look at subclassing the opengl-renderer,
reusing as much code as possible, maybe just replacing the text
drawing routines.
You can have two approaches for the top-level printing stuff:
1. make it the fltk printer device (I think the backend class in
graphics.cc has stupor for printing in the backend)
2. make a operate "ps" backend, which might be better since it could
be reused by future backends, and also might be independent of the
screen  - i.e. enable batch production of graphs. The diadvantage is
you have some coding overhead in implementing some stuff from the
backend class.
