        !            22: .I lpc
        !            23: program provides local control over line printer activity.
        !            24: The major commands and their intended use will be described.
        !            25: The command format and remaining commands are described in

        !            32: then disables printing (preventing new daemons from being started by
        !            33: .IR lpr ).
        !            34: This is normally used to forcibly restart a hung line printer daemon
        !            35: (i.e., \fIlpq\fP reports that there is a daemon present but nothing is
        !            36: happening).  It does not remove any jobs from the queue
        !            37: (use the \fIlprm\fP command instead).
        !            38: .I Start
        !            39: enables printing and requests \fIlpd\fP to start printing jobs.

        !            46: .I lpr
        !            47: from putting new jobs in the spool queue.  It is frequently convenient
        !            48: to turn spooling off while testing new line printer filters since the
        !            49: .I root
        !            50: user can still use
        !            51: .I lpr
        !            52: to put jobs in the queue but no one else can.
        !            53: The other main use is to prevent users from putting jobs in the queue
        !            54: when the printer is expected to be unavailable for a long time.

        !            58: .I Restart
        !            59: allows ordinary users to restart printer daemons when
        !            60: .I lpq
        !            61: reports that there is no daemon present.

        !            65: .I Stop
        !            66: halts a spooling daemon after the current job completes;
        !            67: this also disables printing.  This is a clean way to shutdown a
        !            68: printer to do maintenance, etc.  Note that users can still enter jobs in a

        !            74: .I Topq
        !            75: places jobs at the top of a printer queue.  This can be used
        !            76: to reorder high priority jobs since
        !            77: .I lpr
        !            78: only provides first-come-first-serve ordering of jobs.
