Unrecoverable problem example:

  1. The destination (printer) object becomes disabled and the icon changes to black.
  2. The job object changes to the pending state.
  3. Later, the printer power is restored.
  4. The operator must enable the destination (printer) object.
  5. Jobs start printing on the printer in the order they have been scheduled.

All 300 pages of the job that were printing during the power failure print again.
