Ahh, I guess I stand corrected.

gnome-print is pretty new. I think this is how he's solved the printing
problem in the past?

Check out http://zedzone.mmc.com.au/~zucchi/printing.html
Yes, they are both anti-aliased. Sure, one uses metafont fonts, but
you can plainly see that ghostscript's renderer is pretty awful
(and that xdvi's is very nice!).

We are not writing a postscript interpreter. We are writing a printing
system! We already have the rasteriser, we just have to bolt
on some dithering and control code stuff.

Well as soon as we have to write one, most of the others are 'cheap'.
And writing one isn't very hard.

Resources? We've seen a few times already its easier just to start
Look at those pictures again, do you really want that as state of
the art unix printing?
