Options for the lp command can appear in any order and can be mixed
The cancel command has no options. [Tru64 UNIX] Specifies one or more
country-specific options. See lpr(1) for details about these options.
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.
Selects printer as the device to do the printing (also known as the
printing destination). Under certain conditions (printer unavailabil‐
ity, file space limitations, and so on), requests for specific destina‐
tions 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.) 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. Prints number copies (default
of 1). 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. Suppresses messages from lp, such as “request id is
...”. Prints title on the banner page of the output. Functions like
-m (for compatibility reasons).
Specifies one or more files to be printed. Cancel the request with the
request ID. Cancel all requests made by you with that printer as the
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 com‐
mand (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.)
The following exit values are returned by both the cancel and lp com‐
mands: Successful completion. An error occurred.
The following environment variables affect the execution of lp and can‐
cel: 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 internationaliza‐
tion variables contain an invalid setting, the utility behaves as if
none of the variables had been defined. If set to a non-empty string
value, overrides the values of all the other internationalization vari‐
ables. 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). Determines the locale for the
format and contents of diagnostic messages written to standard error.
Determines the format of date and time strings displayed in the banner.
Determines the output device destination if the -d option is not used
with the lp command. Determines the location of message catalogues for
the processing of LC_MESSAGES. Determines the output device destina‐
tion if the -d option is not used with lp command and the LPDEST envi‐
ronment variable is not set.
