NAME
lp, cancel - send/cancel requests to an line printer
SYNOPSIS
lp [-c] [-ddest] [-m] [-nnumber] [-ooption] [-s] [-ttitle]
[-w] files
cancel [ids] [printers]
DESCRIPTION
lp arranges for the named files and associated information
(collectively called a request) to be printed by a line
printer. Note that files must be readable by the user id lp
since /usr/bin/lp is setuid to lp. If the permissions on
files do not allow lp to read them, files must be piped to
lp(1) to print them. (For example, cat files| lp).
If no filenames are mentioned, the standard input is
assumed. The filename - stands for the standard input and
may be supplied on the command line in conjunction with
named files. The order in which files appear is the same
order in which they will be printed.
lp associates a unique id with each request and prints it on
the standard output. This id can be used later to cancel
(see below) or find the status (see lpstat(1)) of the
request.
The following flag options to lp may appear in any order and
may be intermixed with filenames:
-c Make copies of the files to be printed immediately
when lp is invoked. Normally, files will not be
copied, but will be linked whenever possible. If
the -c flag option is not given, then the user
should be careful not to remove any of the files
before the request has been printed in its
entirety. It should also be noted that in the
absence of the -c flag option, any changes made to
the named files after the request is made but
before it is printed will be reflected in the
printed output.
-ddest Choose dest as the printer or class of printers
that is to do the printing. If dest is a printer,
then the request will be printed only on that
specific printer. If dest is a class of printers,
then the request will be printed on the first
available printer that is a member of the class.
Under certain conditions (printer unavailability,
file space limitation, etc.), requests for
specific destinations may not be accepted (see
accept(1M) and lpstat(1)). By default, dest is

taken from the environment variable LPDEST (if it
is set). Otherwise, a default destination (if one
exists) for the computer system is used.
Destination names vary between systems (see
lpstat(1)).
-m Send mail via mail(1) after the files have been
printed. By default, no mail is sent upon normal
completion of the print request.
-nnumber Print number copies (default of 1) of the output.
-ooption Specify printer-dependent or class-dependent
options. Several such options may be collected by
specifying the -o keyletter more than once. For
more information about what is valid for options,
see the section ``Models'' in lpadmin(1M).
-s Suppress messages from lp(1) such as ``request id
is ....''
-ttitle Print title on the banner page of the output.
-w Write a message on the user's terminal after the
files have been printed. If the user is not
logged in, then mail will be sent instead.
cancel cancels line printer requests that were made by the
lp(1) command. The command line arguments may be either
request ids (as returned by lp(1)) or printer names (for a
complete list, use lpstat(1)). Specifying a request id
cancels the associated request even if it is currently
printing. Specifying a printer cancels the request which is
currently printing on that printer. In either case, the
cancellation of a request that is currently printing frees
the printer to print its next available request.
NOTES
lp is an AT&T command originally intended for use with line
printers, but flexible enough to be useful with other
devices. lpr(1) performs a parallel function, but is
nevertheless a distinct command.
