lp(1)
NAME
lp, cancel - Sends or cancels a printing request
SYNOPSIS
lp [-cmsw] [-A options] [-o option] [-d printer] [-n copies] [-t title]
[file...]
cancel [request_ID...] printer...
cancel request_ID... [printer...]
STANDARDS
Interfaces documented on this reference page conform to industry standards
as follows:
lp: XCU5.0
cancel: XCU5.0
Refer to the standards(5) reference page for more information about
industry standards and associated tags.
OPTIONS
Options for the lp command can appear in any order and can be mixed with
filenames.
The cancel command has no options.
-A options
[Tru64 UNIX] Specifies one or more country-specific options. See
lpr(1) for details about these options.
-c Makes copies of the files to be printed immediately when lp is invoked.
Normally, files are not copied, but are linked whenever possible. If
the -c option is not given, be careful not to remove any of the files
before the request is finished printing. Note also that in the absence
of the -c option any changes made to the named files after the request
is made, but before it is printed, are reflected in the printed output.
-d printer
Selects printer as the device to do the printing (also known as the
printing destination). Under certain conditions (printer
unavailability, file space limitations, and so on), requests for
specific destinations cannot be accepted. By default, printer is taken
from the LPDEST environment variable if it is set. Otherwise, the
PRINTER environment variable or a default destination, if one exists,
for the system is used. Destination names vary between systems. (See
the lpq(1) and lpstat(1) reference pages.)
-m Sends mail (see the mailx(1) reference page) after the files are
printed. By default, no mail is sent upon normal completion of the
print request.
-n number
Prints number copies (default of 1).
-o option
This option is recognized as valid option by the command-line parser,
but is not supported on a Tru64 UNIX system. On other systems,
multiple -o options can be used to specify printer-dependent or class-
dependent options.
-s Suppresses messages from lp, such as "request id is ...".
-t title
Prints title on the banner page of the output.
-w Functions like -m (for compatibility reasons).
OPERANDS
file...
Specifies one or more files to be printed.
request_ID
Cancel the request with the request ID.
printer
Cancel all requests made by you with that printer as the destination.
DESCRIPTION
The lp command sends the specified files and associated information
(collectively called a request) to a line printer for printing. The cancel
command cancels printing requests.
The lp command associates a unique ID with each request and prints it on
the standard output. If you do not specify a file, or specify a - (dash)
in place of a file, lp accepts standard input at this point in the list of
files.
The cancel command cancels printer requests made by the lp or lpr command
(see lpr(1)). You can specify either request_ID, to cancel the request
with that request ID, or printer, to cancel all requests made by you with
that printer as the destination. (If you are operating with superuser
authority, all requests to that printer are canceled, including those of
other users.) A specified request is canceled even if it is currently
printing, and the printer is freed to print the next available request. The
cancel command is marked LEGACY in XCU Issue 5.
You can also use the request ID to find the status of the request. (See the
lpq(1) and lpstat(1) reference pages.)
EXIT STATUS
The following exit values are returned by both the cancel and lp commands:
0 Successful completion.
>0 An error occurred.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of lp and cancel:
LANG
Provides a default value for the internationalization variables that
are unset or null. If LANG is unset or null, the corresponding value
from the default locale is used. If any of the internationalization
variables contain an invalid setting, the utility behaves as if none of
the variables had been defined.
LC_ALL
If set to a non-empty string value, overrides the values of all the
other internationalization variables.
LC_CTYPE
Determines the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to multi-
byte characters in arguments).
LC_MESSAGES
Determines the locale for the format and contents of diagnostic
messages written to standard error.
LC_TIME
Determines the format of date and time strings displayed in the banner.
LPDEST
Determines the output device destination if the -d option is not used
with the lp command.
NLSPATH
Determines the location of message catalogues for the processing of
LC_MESSAGES.
PRINTER
Determines the output device destination if the -d option is not used
with lp command and the LPDEST environment variable is not set.
