  33  * Class JobPriority is an integer valued printing attribute class that
  34  * specifies a print job's priority.
  35  * <P>
  36  * If a JobPriority attribute is specified for a Print Job, it specifies a
  37  * priority for scheduling the job. A higher value specifies a higher priority.
  38  * The value 1 indicates the lowest possible priority. The value 100 indicates
  39  * the highest possible priority. Among those jobs that are ready to print, a
  40  * printer must print all jobs with a priority value of <I>n</I> before printing
  41  * those with a priority value of <I>n</I>-1 for all <I>n.</I>
  42  * <P>
  43  * If the client does not specify a JobPriority attribute for a Print Job and
  44  * the printer does support the JobPriority attribute, the printer must use an
  45  * implementation-defined default JobPriority value.
  46  * <P>
  47  * The client can always specify any job priority value from 1 to 100 for a job.
  48  * However, a Print Service instance may support fewer than 100 different
  49  * job priority levels. If this is the case, the Print Service instance
  50  * automatically maps the client-specified job priority value to one of the
  51  * supported job priority levels, dividing the 100 job priority values equally
  52  * among the available job priority levels.
  53  * <P>
  54  * <B>IPP Compatibility:</B> The integer value gives the IPP integer value. The
  55  * category name returned by {@code getName()} gives the IPP attribute
  56  * name.
