Class JobPriority is an integer valued printing attribute class that
specifies a print job's priority.
If a JobPriority attribute is specified for a Print Job, it specifies a
priority for scheduling the job. A higher value specifies a higher priority.
The value 1 indicates the lowest possible priority. The value 100 indicates
the highest possible priority. Among those jobs that are ready to print, a
printer must print all jobs with a priority value of n before printing
those with a priority value of n-1 for all n.
If the client does not specify a JobPriority attribute for a Print Job and
the printer does support the JobPriority attribute, the printer must use an
implementation-defined default JobPriority value.
The client can always specify any job priority value from 1 to 100 for a job.
However, a Print Service instance may support fewer than 100 different
job priority levels. If this is the case, the Print Service instance
automatically maps the client-specified job priority value to one of the
supported job priority levels, dividing the 100 job priority values equally
among the available job priority levels.
IPP Compatibility: The integer value gives the IPP integer value. The
category name returned by getName() gives the IPP attribute
name.
