The printer state reported on the web page is the scheduler's state
of the queue.  Normally a queue will stay in the "processing" state
until the printer has either been sent all data or (for some backends)
the printer has signaled that it has completely printed a job.

Similarly, jobs are not completed until the backend exits, which can
either mean all data has been sent (most local connections) or
the printer has indicated the job has been completely printed (most
network connections).
