Correct; I've been meaning to try that but haven't gotten back to it on
my to-do list.  

First I have to make a text stream into a PDF, so I have something to
send. Surprisingly I've been able to find no code to steal which does
that; which means it will take longer. :(  [clumsily thunking out to
commands like "a2ps", etc... is strictly forbidden in this code-base;
and that seems how a lot of people seem to hand it].
