Just flushing the printer queue every twenty seconds, or some other time
interval isn't what's really needed, though. 

What's needed is to flush the queue after 20 seconds (or some other
configurable time limit) of *non-activity*.  Suppose you've got Ventura
blowing a forty page document to a laser, with lots of pretty pictures. 
If the queue gets flushed every twenty seconds, you'll probably get
about half the first page out, and then about a half page every twenty
seconds or so, but not quite what you wanted.  I hope support@ism780c
just stated how it worked incorrectly, 'cause what they say they're
going to deliver isn't what's needed.
