There was a bit of a discussion about this on the linuxppc list.  The general
consensus there was "it's too complicated, go and buy a localtalk to ethernet
bridge or an ethernet to parallel box.  They are slightly more expensive, but
easy to set up and they WORK".

However, one person managed to get PowerPrint printing half a page before it
froze.  He posted a copy of his printcap and his filter.  I could post them up
here if people don't object.

So it seems to work a bit.
