[STR New]

When cancelling a job, the backend ignores SIGTERM and continues printing. 
I understand this is due to the desire to allow the filter to make the
printer eject the page or otherwise finish the job off cleanly, but it
means that (a) the printer buffer and (b) the pipe buffer between the
filter and the backend get to spool onto the printer even after the job is
cancelled.

There must be a better way!  For example, the parallel backend ought to be
given the opportunity to reset the device.
