ISO DPA: Job-owner
This attribute supplies the name of the human owner of the
print-job.
The value of job-owner will often be the same as job-
originator. The job-owner will be different from job-originator
when the job has been submitted by the originator on behalf of
the owner. This attribute is not to take the place of the
security parameters or the access-and-accounting attributes.
If this attribute is not specified, the value of user-name or
job-originator should be used for any circumstances which
require a value for job-owner.
