       lprm - remove jobs from the printer queue

       lprm [ -Pprinter ] [ - ] [ job # ...  ] [ username ...  ]

       lprm  removes a job or jobs from a printer's spooling queue.  Since the
       spool directory is protected from users, using  lprm  is  normally  the
       only method by which a user can remove a job.

       Without  any  arguments, lprm deletes the job that is currently active,
       provided that the user who invoked lprm owns that job.

       When the super-user specifies a username, lprm removes all jobs belong-
       ing to that user.

       You  can  remove a specific job by supplying its job number as an argu-
       ment, which you can obtain using lpq(1).  For example:

              example% lpq -Phost
              host is ready and printing
              Rank Owner     Job  Files     Total Size
              active    wendy     385  standard input 35501 bytes
              example% lprm -Phost 385

       lprm reports the names of any files it removes, and is silent if  there
       are no applicable jobs to remove.

       lprm  kills  the  active  printer daemon, if necessary, before removing
       spooled jobs; it restarts the daemon when through.

       -Pprinter      Specify the queue associated with  a  specific  printer.
                      Otherwise the value of the PRINTER variable in the envi-
                      ronment is used.  If this variable is unset,  the  queue
                      for the default printer is used.

       -              Remove  all jobs owned by you.  If invoked by the super-
                      user, all jobs in the spool are removed.  (Job ownership
                      is  determined by the user's login name and host name on
                      the machine where the lpr command was invoked).

       /etc/printcap       printer characteristics file
       /var/spool/*        spooling directories
       /var/spool/l*/lock  lock file used to obtain the  pid  of  the  current
                           daemon  and  the job number of the currently active

       lpr(1), lpq(1), lpd(8)

       lprm: printer: cannot restart printer daemon
              The connection to lpd on the local machine failed.  This usually
              means  the  printer  server  started at boot time has died or is
              hung.  If it is hung, the master lpd(8) daemon may  have  to  be
              killed and a new one started.

       Since  race  conditions  are  possible  when updating the lock file, an
       active job may be incorrectly identified for removal by an lprm command
       issued  with  no arguments.  During the interval between an lpq(1) com-
       mand and the execution of lprm, the next job in line  may  have  become
       active;  that job may be removed unintentionally if it is owned by you.
       To avoid this, supply lprm with the job number to remove when a  criti-
       cal job that you own is next in line.

       Only the super-user can remove print jobs submitted from another host.
