lpr

Print on a line printer

Syntax:

lpr [-#num] [-1234font] [-cdfghlmnprstv] [-C class] 
    [-i [numcols]] [-J job] [-Pprinter] [-T title] 
    [-U user] [-wnum] [filename...]

Options:

-#num

The number of copies desired of each file named. For example:

lpr -#3 foo.c bar.c more.c 
      

results in three copies of the file foo.c, followed by three copies of the file bar.c, etc. On the other hand:

cat foo.c bar.c more.c | lpr -#3
      

gives three copies of the concatenation of the files. Often a site disables this feature to encourage use of a photocopier instead.

-[1234]font

Specifies a font to be mounted on font position i.

-C class

Job classification to use on the burst page. For example:

lpr -C EECS foo.c
      

causes the system name (the name returned by hostname) to be replaced on the burst page by EECS, and the file foo.c to be printed.

-c

The files are assumed to contain data produced by cifplot.

-d

The files are assumed to contain data from tex.

-f

Use a filter that interprets the first character of each line as a standard FORTRAN carriage control character.

-g

The files are assumed to contain standard plot data.

-h

Suppress the printing of the burst page.

-i [numcols]

Indent the output. If the next argument is numeric (numcols), it's used as the number of blanks to be printed before each line; otherwise, 8 characters are printed.

-J job

The job name to print on the burst page. Normally, the first file's name is used.

-l

Use a filter that lets control characters be printed and suppresses page breaks.

-m

Send mail upon completion.

-n

The files are assumed to contain data from ditroff.

-Pprinter

Force output to a specific printer. Normally, the default printer is used (site dependent), or the value of the environment variable PRINTER is used.

-p

Use pr to format the files.

-r

Remove the file upon completion.

-s

Use symbolic links.

-T title

The title name for pr (instead of the filename).

-t

The files are assumed to contain data from troff.

-U user

The user name to print on the burst page, also for accounting purposes. This option is honored only if the real userid is daemon (or that specified in the /etc/printcap file instead of daemon), and is intended for those instances where print filters wish to re-queue jobs.

-v

The files are assumed to contain a raster image.

-wnum

Use num as the page width for pr.

filename

The name of the file to print.

Description:

The lpr utility uses the spooling daemon lpd to print the named files when facilities become available. If no names appear, the standard input is assumed.

Diagnostics

If a user other than root prints a file and spooling is disabled, lpr prints a message saying so and won't put jobs in the queue.

If a connection to lpd on the local machine can't be made, lpr says that the daemon can't be started.

Environment variables:

PRINTER

An alternate default printer.

DONT_USE_LINK_UNLINK

Use rename() instead of link() or unlink().

Caveats:

If you try to spool a file that's too large, it's truncated.

If the lpd daemon has any problems (e.g. it can't find the spool file), it might print some diagnostics in its log file.
