NAME

     lpr — off line print

SYNOPSIS

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

DESCRIPTION

     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.

     -d      The files are assumed to contain data from tex (DVI format from Stanford).

     -f      Use a filter which 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 which 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.

     -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:

     -h      Suppress the printing of the burst page.

     -m      Send mail upon completion.

     -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.

     -q      Queue the print job but do not start the spooling daemon.

     -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 3 copies of the file foo.c, followed by 3 copies of the file bar.c, etc.  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 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.

     -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, 8 characters are printed.

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

     -T title
             Title name for pr(1), instead of the file name.

     -U user
             User name 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.

     -wnum   Uses num as the page width for pr(1).

ENVIRONMENT

     If the following environment variable exists, it is used by lpr:

     PRINTER  Specifies an alternate default printer.

FILES

     /etc/passwd              local users database
     /etc/printcap            printer capabilities database
     /usr/sbin/lpd*           line printer daemons
     /var/spool/output/*      directories used for spooling
     /var/spool/output/*/cf*  daemon control files
     /var/spool/output/*/df*  data files specified in “cf” files
     /var/spool/output/*/tf*  temporary copies of “cf” files

DIAGNOSTICS

     If you try to spool too large a file, it will be truncated.  If a user other than root prints a file and
     spooling is disabled, lpr will print a message saying so and will not put jobs in the queue.  If a
     connection to lpd(8) on the local machine cannot be made, lpr will say that the daemon cannot be started.
     Diagnostics may be printed in the daemon's log file regarding missing spool files by lpd(8).

HISTORY

     The lpr command appeared in 3BSD.

BUGS

     Fonts for troff(1) and tex reside on the host with the printer.  It is currently not possible to use local
     font libraries.
