Oh, I won't! However implements this gets to say how it's done; good
to hear you have an opinion that you're willing to back with code :-)

That's not *that* hard. And even then, we could just say "generic PS
printer support is what we do" and provide it on the XO itself and
it'd make sense too. I suspect we can aggressively trim cups to only
only eat 20% of your NAND.
But printing it's a much broader problem. You'll want quotas,
priorities, printer selection and related management to get something
usable in a school environment you get ac lot of human/social
considerations. PS vs PCL is not where the intersting problem is. I've
worked with several secondary schools and tertiaries, all using
various schemes for this, all imperfect and leaky, but quite
informative about the challenges.
It's a big task. Right now I have other priorities that will take a
while. Printing *is* important, but other things are more important
and more reachable right now -- I'm pleased to hear others care a lot
about this. Hopefully enough to get moving on this!
