Print on a line printer
lpr [-#num] [-1234font] [-cdfghlmnprstv] [-C class]
[-i [numcols]] [-J job] [-Pprinter] [-T title]
[-U user] [-wnum] [filename...]
- 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
- 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.
- The files are assumed to contain data produced by cifplot.
- The files are assumed to contain data from tex.
- Use a filter that interprets the first character
of each line as a standard FORTRAN carriage control character.
- The files are assumed to contain standard plot data.
- 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.
- Use a filter that lets control characters be
printed and suppresses page breaks.
- Send mail upon completion.
- The files are assumed to contain data from ditroff.
- Force output to a specific printer.
The printer argument must be a printer name that's
Normally, lpr uses the (site-dependent) default printer, or
the one specified by the PRINTER environment variable.
to format the files.
- Remove the file upon completion.
- Use symbolic links.
- -T title
- The title name for pr (instead of the filename).
- 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
- The files are assumed to contain a raster image.
- Use num as the page width for pr.
- The name of the file to print.
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
||This utility needs to have the setuid (“set user ID”)
bit set in its permissions.
If you use
on a Windows host to include this utility in an image,
use the perms attribute to specify its permissions explicitly,
and the uid and gid attributes to set the ownership
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
- An alternate default printer.
- Use rename() instead of link() or unlink().
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.
