Be sure you suppress the cr/lf on that echo or the printer will think
you've started a new job.  The control-D needs to be the very last
character of the job stream.

If you're using Adobe's ehandler.ps to make up for the lack of a return
path for error reports this is important.  Incomplete jobs elicit a timeout
error from PostScript.
