This depends on the printer. But for HP printers that have PCL
support, it is MANDATORY (yes, required!) that you send 
<ESC>%-12345X at the START and END of a job.
The one at the START will cause any pages hanging around to be
ejected; the one at the END will cause the pages to be flushed.

Sigh...
