lp(1)							      General Commands Manual							     lp(1)

Name
       lp - send requests to an LP line printer

Syntax
       lp [-c] [-d dest] [-n number] [-] [files]

Description
       The command arranges for the named files and associated information (collectively called a request) to be printed by a line printer.  If no
       file names are mentioned, the standard input is assumed.  When a file name is designated by a minus sign (-) it	stands	for  the  standard
       input  and may be supplied on the command line in conjunction with named files.	The order in which files appear is the same order in which
       they are printed.

       This command exists for X/OPEN compatibility.

Options
       The following options to may appear in any order and may be intermixed with file names:

       -c	   Makes copies of the files to be printed immediately when is invoked.  Normally, files are not copied, but are  linked  whenever
		   possible.  If the -c option is not given, then the user should be careful not to remove any of the files before the request has
		   been printed in its entirety.  It should also be noted that without the -c option, any changes made to the  named  files  after
		   the request is made but before it is printed are reflected in the printed output.

       -d dest	   Chooses  dest  as  the  printer that is to do the printing.	If dest is a printer, then the request is printed on that specific
		   printer.  By default, dest is taken from the environment variable PRINTER if it is set.  Otherwise, a default destination,  lp,
		   is used.

       -n number   Prints number copies (default of 1) of the output.

Files
       /etc/passwd	      personal identification
       /etc/printcap	      printer capabilities data base
       /usr/lib/lpd*	      line printer daemons
       /usr/spool/*	      directories used for spooling
       /usr/spool/*/cf*       daemon control files
       /usr/spool/*/df*       data files specified in cf files
       /usr/spool/*/tf*       temporary copies of cf files

lprm(1) 						      General Commands Manual							   lprm(1)

Name
       lprm - remove jobs from line printer queue

Syntax
       lprm [-Pprinter] [-] [job #...] [user...]

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

       The command without any arguments deletes the currently active job if it is owned by the user who invoked

       If the - flag is specified, removes all jobs which a user owns.	If the super-user employs this flag, the spool queue is emptied  entirely.
       The owner is determined by the user's login name and host name on the machine where the command was invoked.

       Specifying  a user's name, or list of user names, causes to attempt to remove any jobs queued belonging to that user (or users).  This form
       of invoking is useful only to the super-user.

       A user may dequeue an individual job by specifying its job number.  This number may be obtained from the program.  For example,
       % lpq -l

       1st: ken  [job #013ucbarpa]
	    (standard input)	100 bytes
       % lprm 13

       The command announces the names of any files it removes and is silent if there are no jobs in the queue which match the request list.

       The command kills off an active daemon, if necessary, before removing any spooling files.  If a daemon is killed, a new	one  is  automati-
       cally restarted upon completion of file removals.

Options
       -		   Removes all jobs owned by you only.

       -P printer	   Removes jobs from specified printer.  It may be used to specify the queue associated with a specific printer (otherwise
			   the default printer, or the value of the PRINTER variable in the environment is used).

Restrictions
       Since there are race conditions possible in the update of the lock file, the currently active job may be incorrectly identified.

Diagnostics
       ``Permission denied" if the user tries to remove files other than his own.

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