I can't seem to get the stream to work quite right (it's "Input" by the
way and not "InputStream"

With TProcess.Create(nil) do
  Try
     writeln('Setting LPR command');
     CommandLine:='/usr/bin/lpr'; 
     options:=[poUsePipes];
     Execute;
     FPostScript.Document.SaveToStream(Input);

  finally
     Free;
  end;

But nothing ever happens.  I can call this by saving to a file first and
then passing the path to that to lpr in the commandline param above, but
not if I try to stream it.

What am I doing wrong?

Thanks,
