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.

lpq(1) General Commands Manual lpq(1) Name lpq - spool queue examination program Syntax lpq [ options ] [ job #... ] [ user... ] Description The command examines the spooling area used by for printing files on the printer, and reports the status of jobs. The command invoked without any arguments reports on any jobs currently in the default queue. When jobs are being printed, reports the queue as being ``active''. For each job submitted, reports the user's name, current rank in the queue, the names of files comprising the job, the job identifier and the total size in bytes. The job identifier is a number which may be supplied to to remove a specific job. Job ordering is determined by the FIFO (First In, First Out) algorithm used to scan the spooling directory. When the queue is empty, reports that there are ``no entries''. File names may be unavailable for some jobs, for example, if the command is used without specifying a file name, or if is used in a pipe line. If file names are unavailable, the file name reported by is ``standard input''. Arguments job #... Causes to report on only the job number(s) specified. user... Causes to report on only the jobs for the specified user(s). Options +n Scan and display the spool queue until the queue is empty. The queue is scanned every n seconds, if no argument is specified the queue is scanned every 30 seconds. -l Display the status of each job on more than one line if necessary. If this option is not used, the status of each job is displayed on one line. -Pprinter Report the status of the spool queue for the printer specified. If this option is not used, the spool queue displayed is the one defined by the PRINTER environment variable. If a queue is not defined by the PRINTER environment variable, the spool queue displayed is for the printer named ``lp'' in the file. Restrictions The displayed status of the spool queue may not always be the current status. This is because jobs may be completed after the queue has been examined, but before the status has been displayed. Error Messages Two of the most common error messages from are: Warning: no daemon present (R) A daemon is not available for the specified printer. Refer to the command to find out how to restart the printer daemon. unknown printer (R) The printer specified as an argument to the -P option, doesn't have an entry in the file. Files For manipulating the screen for repeated display To determine printer characteristics The spooling directory, as determined from printcap Control files specifying jobs The lock file to obtain the currently active job See Also lpr(1), lprm(1), lpc(8), lpd(8) lpq(1)
