lpr Command on POWER-based
Platform
Enqueues print jobs.

The lpr command uses a
spooling daemon to print the named File parameter when facilities
become available. If no files are specified, the lpr command
reads from standard input.
| -# Number
| Produces multiple copies of output, using the Number variable
as the number of copies for each file named.
|
| -C Class
| Specifies the print Class as the job classification on the
burst page.
|
| -f
| Uses 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.
|
| -h
| Suppresses printing of the burst page.
Note: The default is to print a header page and not a trailer
page.
|
| -i [Number]
| Indents output Number spaces. If the Number
variable is not given, eight spaces are used as the default.
|
| -j
| Specifies that the message Job number is:
nnn, where nnn is the assigned job number, be
displayed to standard output. This occurs only if the job is submitted
to a local print queue.
|
| -J Job
| Prints the Job variable as the job name on the burst
page. Normally, the lpr command uses the name of the first
file.
|
| -l
| (Lowercase L) Uses a filter which allows control characters to be
printed.
|
| -m
| Sends mail upon completion of spooling.
|
| -n
| Uses a filter which formats files containing ditroff
(device-independent troff) data.
|
| -P Printer
| Forces output to the Printer variable. If this flag is
not specified, the following conditions occur:
- If a default exists, the lpr command uses the
default printer.
- If the LPDEST environment variable is set, then
lpr uses the value specified by the LPDEST
variable. If set, this value is always used, even if the
PRINTER variable is also set.
- If the PRINTER variable is set and no
LPDEST variable is set, then lpr uses the value
specified by the PRINTER environment variable.
Note: Any destination command line options override both the
LPDEST and the PRINTER environment variables.
|
| -p
| Uses the pr command to format the file (lpr -p is
very much like pr | lpr).
|
| -r
| Removes the file upon completion of spooling.
|
| -s
| Prints from the files specified on the command line rather than trying to
copy them (so large files can be printed). This means the data files
should not be modified or removed until they have been printed. Note
that this flag only works on the local host (files sent to remote printer
hosts are copied anyway), and only with named data files. It does not
work if the lpr command is at the end of a pipeline.
|
| -T Title
| Uses the Title variable instead of the file name for the title
used by the pr command.
|
| -w Number
| Uses the Number variable as the page width for the
pr command.
|
- To print three copies of the
files new.index.c,
print.index.c, and more.c, enter:
lpr -#3 new.index.c print.index.c more.c
Prints three copies of the new.index.c file,
three copies of the print.index.c file, and three
copies of the more.c file.
- To print three copies of the
concatenation of three files new.index.c,
print.index.c, and more.c, enter:
cat new.index.c print.index.c more.c | lpr -#3
- To print Operations
on the burst page, followed by file new.index.c,
enter:
lpr -C Operations new.index.c
This replaces the system name (the name returned by host name) with
Operations on the burst page.
- To queue the MyFile file
and return the job number, enter:
lpr -j MyFile
| /usr/sbin/qdaemon
| Queuing daemon.
|
| /etc/qconfig
| Queue configuration file.
|
| /etc/qconfig.bin
| Digested, binary version of the /etc/qconfig file.
|
| /var/spool/lpd/qdir/*
| Queue requests.
|
| /var/spool/lpd/stat/*
| Information on the status of the queues.
|

lpr Command on POWER-based and
Itanium-based Platforms
Note: This is a System V Print Subsystem command.
(BSD) Sends a job to the printer.
/usr/bin/lpr [ -P
printer] [ -#

[ -J job] [ -T title] [ -i [indent] ] [ -w cols] [ -r] [ -m] [

[ -filter_option]

The lpr command forwards printer jobs to a spooling area for
subsequent printing as facilities become available. Each printer job
consists of copies of each file you specify. The spool area
is managed by the line printer spooler, lpsched.
lpr reads from the standard input if no files are specified.
lp is the preferred interface.
Command-line options cannot be combined into a single argument as with some
other commands. The command:
lpr -fs
is not equivalent to
lpr -f -s
Placing the -s flag first, or writing each option as a separate
argument, makes a link as expected.
lpr -p is not precisely equivalent to pr |
lpr. lpr -p puts the current date at the top of each
page, rather than the date last modified.
Fonts for troff and T[E]X reside on the
printer host. It is not possible to use local font libraries.
lpr objects to printing binary files.
If userA uses su to become userB and uses
/usr/bin/lpr, then the printer request will be entered as userB,
not userA
- -P printer
- Send output to the named printer. Otherwise send output
to the printer named in the PRINTER environment variable, or to the
default printer, lp.
- -# copies
- Produce the number of copies indicated for each named
file. For example:
lpr -#3 index.c lookup.c
produces three copies of index.c, followed by three
copies of lookup.c. On the other hand,
cat index.c lookup.c | lpr -#3
generates three copies of the concatenation of the files.
- -C class
- Print class as the job classification on the burst page.
For example,
lpr -C Operations new.index.c
replaces the system name (the name returned by ``hostname'') with
Operations on the burst page, and prints the file
new.index.c.
- -J job
- Print job as the job name on the burst page. Normally,
lpr uses the first file's name.
- -T title
- Use title instead of the file name for the title used by pr.
- -i[indent]
- Indent output indent <Space> characters. Eight
<Space> characters is the default.
- -w cols
- Use cols as the page width for pr.
- -r
- Remove the file upon completion of spooling, or upon completion of
printing with the -s flag.
- -m
- Send mail upon completion.
- -h
- Suppress printing the burst page.
- -s
- Use the full pathnames (not symbolic links) of the files to be printed
rather than trying to copy them. This means the data files should not
be modified or removed until they have been printed. This flag only
prevents copies of local files from being made. Jobs from remote hosts
are copied anyway. The -s flag only works with named data
files; if the lpr command is at the end of a pipeline, the
data is copied to the spool.
- filter_option
- The following single letter options 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.
- -p
- Use pr to format the files (lpr -p is very much like
pr | lpr).
- -l
- Print control characters and suppress page breaks.
- -t
- The files contain troff (cat
phototypesetter) binary data.
- -n
- The files contain data from ditroff (device independent
troff).
- -d
- The files contain data from tex (DVI format from
Stanford).
- -g
- The files contain standard plot data as produced by the routine
plot for the filters used by the printer spooler.
- -v
- The files contain a raster image. The printer must support an
appropriate imaging model such as PostScript in order to print the
image.
- -c
- The files contain data produced by cifplot.
- -f
- Interpret the first character of each line as a standard FORTRAN carriage
control character.
If no filter_option is given (and the printer can interpret
PostScript), the string `%!' as the first two characters of a
file indicates that it contains PostScript commands.
These filter options offer a standard user interface, and all options may
not be available for, nor applicable to, all printers.

- /usr/lib/lp/lpsched
- System V line printer spooler
- /var/spool/lp/tmp/*
- directories used for spooling
- /var/spool/lp/tmp/system/*-0
- spooler control files
- /var/spool/lp/tmp/system/*-N
- (N is an integer and > 0) data files specified in
`*-0' files
- lpr: printer: unknown
printer
- The printer was not found in the LP database. Usually
this is a typing mistake; however, it may indicate that the printer does
not exist on the system. Use lpstat -p to find the
reason.
- lpr: error on opening queue to spooler
- The connection to lpsched on the local machine failed.
This usually means the printer server started at boot time has died or is
hung. Check if the printer spooler daemon /usr/lib/lpsched
is running.
- lpr: printer: printer queue is
disabled
- This means the queue was turned off with
/usr/etc/lpc disable printer
to prevent lpr from putting files in the queue. This is
normally done by the system manager when a printer is going to be down for a
long time. The printer can be turned back on by a privileged user with
lpc.
- lpr: Can't send message to the LP print service
-
- lpr: Can't establish contact with the LP print
service
- These indicate that the LP print service has been stopped. Get help
from the system administrator.
- lpr: Received unexpected message from LP print service
- It is likely there is an error in this software. Get help from
system administrator.
- lpr: There is no filter to convert the file content
- Use the lpstat -p -l command to find a printer that can
handle the file type directly, or consult with your system
administrator.
- lpr: cannot access the file
- Make sure file names are valid.
The lpc command, lpq command, lprm command, and troff command.
