  15.  * JobState is a printing attribute class, an enumeration, that identifies 

  16.  * the current state of a print job. Class JobState defines standard job state 

  17.  * values. A  Print Service implementation only needs to report those job 

  18.  * states which are appropriate for the particular implementation; it does not 

  19.  * have to report every defined job state. The {@link JobStateReasons 

  20.  * JobStateReasons} attribute augments the JobState attribute to give more 

  21.  * detailed information about the job in the given job state.

  24.  * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's 

  25.  * integer value is the IPP enum value.  The <code>toString()</code> method
