[-cdfghlnmprstv] [name ...]
The lpr utility uses a spooling daemon to print the named files when
facilities become available. If no names appear, the standard input is
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. Note
that not all spoolers implement filters for all data types, and some
sites may use these types for other purposes than the ones described
-d The files are assumed to contain data in DVI format from the TeX
-f Use a filter which interprets the first character of each line as
a standard FORTRAN carriage control character.
-l Use a filter which allows control characters to be printed and
suppresses page breaks.
-p Use pr(1) to format the files.
The following options are historical and not directly supported by any
software included in DragonFly.
-c The files are assumed to contain data produced by cifplot(1).
-g The files are assumed to contain standard plot data as produced
by the UNIX plot(3) routines.
-n The files are assumed to contain data from ditroff (device inde-
-t The files are assumed to contain C/A/T phototypesetter commands
from ancient versions of UNIX troff(1).
-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 direc-
tory. 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 photo-
Specifies a font to be mounted on font position i. The daemon
will construct a .railmag file referencing the font pathname.
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
-J job Job name to print on the burst page. Normally, the first file's
name is used.
Use locale specified as argument instead of one found in environ-
ment. (Only effective when filtering through pr(1) is requested
using the -p option.)
Title name for pr(1), instead of the file name.
User name to print on the burst page, also for accounting pur-
poses. 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
Some spoolers, such as LPRng, accept additional per-job options
using a `Z' control line. When -Z is specified, and -p (pr(1))
is not requested, the specified daemon-options will be passed to
the remote LPRng spooler.
The output is indented by (numcols).
-w num Uses num as the page width for pr(1).
If the following environment variable exists, it is used by lpr:
PRINTER Specifies an alternate default printer.
/etc/passwd Personal identification.
/etc/printcap Printer capabilities data base.
/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.
If you try to spool too large a file, it will be truncated. The lpr
utility will object to printing binary files. 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).
lpq(1), lprm(1), pr(1), symlink(2), printcap(5), lpc(8), lpd(8)
The lpr command appeared in 3BSD.
Fonts for troff(1) and TeX reside on the host with the printer. It is
currently not possible to use local font libraries.
The `Z' control file line is used for two different purposes; for stan-
dard DragonFly lpd(8), it specifies a locale to be passed to pr(1). For
LPRng lpd(8), it specifies additional options to be interpreted by the
spooler's input and output filters. When submitting jobs via lpr, -p -L
locale is used in the former context, and -Z daemon-options is used in
