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