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).
-
-
- -o
- The files are assumed to be in postscript format.
-
-
- -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:
-
-
- -h
- Suppress the printing of the burst page.
-
-
- -m
- Send mail upon completion.
-
-
- -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.
-
-
- -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.
Normally
lpr works silently except for diagnostic messages.
The following option changes this behavior.
-
-
- -R
- Writes a message to standard output containing the unique
number which is used to identify this job. This number can be used to
cancel (see lprm(1)) or find
the status (see lpq(1)) of the
job.
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,
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 by
(numcols).
-
-
- -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 alternative default printer.
FILES
- /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.
DIAGNOSTICS
If you try to spool too large a file, it will be truncated.
lpr 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).

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.
