VMS Help PRINT, Qualifiers, /PRIORITY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PRIORITY=n

    Requires OPER (operator) or ALTPRI (alter priority) privilege
    to raise the priority above the queue's maximum scheduling
    priority.

    Specifies the job-scheduling priority of the print job. The value
    of the parameter n can be from 0 through 255, where 0 is the
    lowest priority and 255 is the highest. The default value of n
    is the value of the system parameter DEFQUEPRI. No privilege
    is needed to set the priority lower than the queue's maximum
    scheduling priority.
