  27  * Package javax.print.event contains event classes and listener interfaces.

  29  * They may be used to monitor both print services (such as printers going
  30  * on-line &amp; off-line), and the progress of a specific print job.
  31  * <p>
  32  * Please note: In the javax.print APIs, a null reference parameter to methods
  33  * is incorrect unless explicitly documented on the method as having a
  34  * meaningful interpretation. Usage to the contrary is incorrect coding and may
  35  * result in a run time exception either immediately or at some later time.
  36  * IllegalArgumentException and NullPointerException are examples of typical and
  37  * acceptable run time exceptions for such cases.
