Actually, the two ppd's in my gs distribution are for a Canon Bubblejet
printer, which I guess is not a postscript printer...

So what are the complains of "having to code in postscript" coming from
? Why people don't simply use the functions provided by gnome-print

Actually I haven't seen any problem with font rendering at this time.
Maybe the problem is coming from the fonts themselves?
What if you try with gs -sDEVICE=x11alpha?

What I mean is that ghostscript *may be* on of the solutions used.
Personnally I think it does a wonderful job. Where I am reluctant with
it is the fact that ghostscript contains a bunch of drivers totally
unuseful. You can't select the installation of the only needed drivers
without recompiling it. For the rest, I think that if ghostscript is
still failing in some points after 10 years, it means that we'll have
trouble setting up our own postscript interpreters+printer drivers. So
the solution I see is still to enhance ghostscript with the feature it's

Exactly. Just to send a code such as "^]33\0x234..cryptic blahblah..".
But it doesn't mean we have to rewrite the printer driver from scratch.

So let's help them cleaning up their code?
