-a Remove all requests the user owns on each printer. The owner is determined by the user’s
login name and the host name of the machine where the lp command was invoked.
-e Empty the spool queue of all requests for each printer. Only users with appropriate
privileges can use this option.
-i Cancel only local requests.
-uuser Remove any requests belonging to user. You can repeat the -u option to specify more
users. Only users with appropriate privileges can use this option.
Printing Overview
A printer can print requests from one or two destination queues: its own private queue and an optional
class queue, which can serve one or more printers. The destination queues are set up with the lpadmin
command. The lp command places a printing request into a printer or class destination queue as directed
by a user. The lpsched scheduler directs the requests from the destination queues to the printers. The
accept and reject commands control whether lp can place requests in the destination queues. The
enable and disable commands control whether lpsched can send a queued request to a printer. If a
printer has two queues and one queue is rejecting requests, users can still direct requests to the other desti-
nation queue and have the requests printed. lpstat reports the current status of the destination queues
and the scheduler. See enable(1), lpstat(1), accept(1M), and lpadmin(1M).
EXTERNAL INFLUENCES
Environment Variables
LANG determines the locale to use for the locale categories when both LC_ALL and the corresponding
environment variable (beginning with LC_) do not specify a locale. If LANG is not set or is set to the
empty string, a default of "C" (see lang(5)) is used.
LC_ALL determines the locale to use to override any values for locale categories specified by the setting of
LANG or any environment variables beginningwith LC_.
LC_CTYPE determines the locale for interpretation of sequences of bytes of text data as characters (e.g.,
single- verses multibyte characters in arguments and input files).
LC_MESSAGES determines the language in which messages are displayed.
LPDEST determines the output device or destination. If the LPDEST environment variable is not set, the
PRINTER environment variable is used. The -d dest option takes precedence over LPDEST. Results are
undefined when
-d is not specified and LPDEST contains a value that is not a valid device or destination
name.
PRINTER determines the output device or destination. If the LPDEST and PRINTER environment vari-
ables are not set, an unspecified output device is used. The -d dest option and the
LPDEST environment
variable takes precedence over
PRINTER. Results are undefined when -d is not specified,
LPDEST is
unset, and
PRINTER contains a value that is not a valid device or destination name.
If any internationalization variable contains an invalid setting, the commands behave as if all international-
ization variablesare set to "C". See environ(5).
International Code Set Support
Single- and multibyte character code sets are supported.
RETURN VALUE
Exit values are:
0 Successful completion.
>0 Error condition occurred.
EXAMPLES
For a HP2934A printer named lp2, configured with an interface script that defines the -c option to cause
the printer to print in a compressed mode, use the following command to print myfile with compressed
print on lp2:
lp -dlp2 -oc myfile
lp
can be used at the end of a pipeline to print the results of a previous command. It is commonly used
with the pr command (see pr(1)) to print formatted output. For a default printer, to format file
.pro-
file
into pages and print three copies of it:
