UNIX/LINUX Command – lpr


lpr—Offline print


lpr [-P printer] [-# num] [-C class] [-J job] [-T title] [-U user] [-i [numcols]] [-1234 font] [-w num] [-cdfghlnmprstv] [name …]


lpr uses a spooling daemon to print the named files when facilities become available. If no names appear, the standard input is assumed.
The following single-letter options are used to notify the line printer spooler that the files are not standard text files. The spooling daemon will use the appropriate filters to print the data accordingly.
–c       The files are assumed to contain data produced by cifplot(1).
–d       The files are assumed to contain data from TeX (DVI format from Stanford).
–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 as produced by the plot routines. (See also plot for the filters used by the printer spooler.)
–l        Use a filter that allows control characters to be printed and suppresses page breaks.
–n       The files are assumed to contain data from ditroff (device independent troff).
–p       Use pr(1) to format the files (equivalent to print).
–t        The files are assumed to contain data from troff(1) (cat phototypesetter commands).
–v       The files are assumed to contain a raster image for devices like the Benson Varian.

These options apply to the handling of the print job:

–P         Force output to a specific printer. Normally, the default printer is used (site-dependent), or the value of the environment variable PRINTER is used.
–h         Suppress the printing of the burst page.
–m        Send mail upon completion.
–r          Remove the file upon completion of spooling or upon completion of printing (with the -s option).
–s          Use symbolic links. Usually, files are copied to the spool directory. The -s option will use symlink(2) to link data files rather than trying to copy them so large files can be printed. This means the files should not be modified or removed until they have been printed.

The remaining options apply to copies, the page display, and headers:

-# num The quantity num is the number of copies desired of each file named. For example,
lpr –#3 foo.c bar.c more.c
would result in three copies of the file foo.c, followed by three copies of the file bar.c, and so on. On the other hand,
cat foo.c bar.c more.c | lpr –#3
will give three copies of the concatenation of the files. Often a site will disable this feature to encourage use of a photocopier instead.
1234 font Specifies a font to be mounted on font position i. The daemon will construct a .railmag file referencing the font pathname.
–C Ar 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(1)—to be replaced on the burst page by EECS, and the file foo.c to be printed.
–J Ar job Job name to print on the burst page. Normally, the first file’s name is used.
-T Ar title Title name for pr(1), instead of the filename.
-U user Username to print on the burst page, also for accounting purposes. This option is only honored if the real user ID is daemon (or that specified in the printcap file instead of daemon), and is intended for those instances where print filters wish to requeue jobs.
-i numcols The output is indented. If the next argument is numeric numcols, it is used as the number of blanks to be printed before each line; otherwise, eight characters are printed.
-w Ns Ar num Uses num as the page width for pr(1).
