lp(1) (Line Printer Spooling Utilities) lp(1)
NAME
lp, cancel - send/cancel requests to an LP print service
SYNOPSIS
lp [printing-options] files
lp -i request-IDs printing-options
cancel [request-IDs] [printers]
cancel -u login_IDs [printers]
DESCRIPTION
The first form of the lp shell command arranges for the named files
and associated information (collectively called a request) to be
printed. If no file names are specified on the shell command line,
the standard input is assumed. The standard input may be specified
along with named files on the shell command line by listing the file
name(s) and specifying - for the standard input. The files will be
printed in the order in which they appear on the shell command line.
The second form of lp is used to change the options for a request.
The print request identified by the request-ID is changed according
to the printing options specified with this shell command. The
printing options available are the same as those with the first form
of the lp shell command. If the request has finished printing, the
change is rejected. If the request is already printing, it will be
stopped and restarted from the beginning (unless the -P option has
been given).
lp associates a unique request-ID with each request and prints it on
the standard output. This request-ID can be used later when
canceling or changing a request, or when determining its status.
[See the section on cancel for details about canceling a request, the
previous paragraph for an explanation of how to change a request, and
lpstat(1) for information about checking the status of a print
request.]
Sending a Print Request
The first form of the lp command is used to send a print request to a
particular printer or group of printers.
Options to lp must always precede file names, but may be listed in
any order. The following options are available for lp:
-c Make copies immediately of the files to be printed when lp is
invoked. Normally, files will not be copied, but will be
linked whenever possible. If the -c 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 if the -c option is not specified,
any changes made to the named files after the request is made
but before it is printed will be reflected in the printed
output.

-d dest
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 (unavailability of printers, file space
limitations, and so on) requests for specific destinations may
not be accepted [see 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)].
-f form-name [-d any]
Print the request on the form form-name. The LP print service
ensures that the form is mounted on the printer. If form-name
is requested with a printer destination that cannot support
the form, the request is rejected. If form-name has not been
defined for the system, or if the user is not allowed to use
the form, the request is rejected [see lpforms(1M)]. When the
-d any option is given, the request is printed on any printer
that has the requested form mounted and can handle all other
needs of the print request.
-H special-handling
Print the request according to the value of special-handling.
Acceptable values for special-handling are hold, resume, and
immediate, as defined below:
hold Don't print the request until notified. If printing has
already begun, stop it. Other print requests will go
ahead of a held request until it is resumed.
resume Resume a held request. If it had been printing when
held, it will be the next request printed, unless
subsequently bumped by an immediate request.
immediate
(Available only to LP administrators)
Print the request next. If more than one request is
assigned immediate, the requests are printed in the
reverse order queued. If a request is currently
printing on the desired printer, you have to put it on
hold to allow the immediate request to print.
-m Send mail [see mail(1)] after the files have been printed. By
default, no mail is sent upon normal completion of the print
request.

-n number
Print number copies (default of 1) of the output.
-o option
Specify printer-dependent options. Several such options may
be collected by specifying the -o keyletter more than once (-o
option1 -o option2 ... -o optionn), or by specifying a list of
options with more than one -o keyletter (i.e., -o option1,
option2, ... optionn). The standard interface recognizes the
following options:
nobanner
Do not print a banner page with this request. (The
administrator can disallow this option at any time.)
nofilebreak
Do not insert a form feed between the files given, if
submitting a job to print more than one file.
length=scaled-decimal-number
Print this request with pages scaled-decimal-number
lines long. A scaled-decimal-number is an optionally
scaled decimal number that gives a size in lines,
columns, inches, or centimeters, as appropriate. The
scale is indicated by appending the letter ``i'' for
inches, or the letter ``c'' for centimeters. For
length or width settings, an unscaled number indicates
lines or columns; for line pitch or character pitch
settings, an unscaled number indicates lines per inch
or characters per inch (the same as a number scaled
with ``i''). For example, length=66 indicates a page
length of 66 lines, length=11i indicates a page length
of 11 inches, and length=27.94c indicates a page length
of 27.94 centimeters.
This option cannot be used with the -f option.
width=scaled-decimal-number
Print this request with page-width set to scaled-
decimal-number columns wide. (See the explanation of
scaled-decimal-numbers in the discussion of length,
above.) This option cannot be used with the -f option.
lpi=scaled-decimal-number
Print this request with the line pitch set to scaled-
decimal-number lines per inch. This option cannot be
used with the -f option.
cpi=scaled-decimal-number
Print this request with the character pitch set to
scaled-decimal-number characters per inch. Character
pitch can also be set to pica (representing 10 columns
7/91 Page 3
lp(1) (Line Printer Spooling Utilities) lp(1)
per inch) or elite (representing 12 columns per inch),
or it can be compressed (representing as many columns
as a printer can handle). There is no standard number
of columns per inch for all printers; see the Terminfo
database [terminfo(4)] for the default character pitch
for your printer.
This option cannot be used with the -f option.
stty=stty-option-list
A list of options valid for the stty command; enclose
the list with quotes if it contains blanks.
-P page-list
Print the pages specified in page-list. This option can be
used only if there is a filter available to handle it;
otherwise, the print request will be rejected.
The page-list may consist of range(s) of numbers, single page
numbers, or a combination of both. The pages will be printed
in ascending order.
-q priority-level
Assign this request priority-level in the printing queue. The
values of priority-level range from 0, the highest priority,
to 39, the lowest priority. If a priority is not specified,
the default for the print service is used, as assigned by the
system administrator.
-s Suppress messages from lp such as those that begin with request
id is.
-S character-set [-d any]
-S print-wheel [-d any]
Print this request using the specified character-set or
print-wheel. If a form was requested and it requires a
character set or print wheel other than the one specified with
the -S option, the request is rejected.
For printers that take print wheels: if the print wheel
specified is not one listed by the administrator as acceptable
for the printer specified in this request, the request is
rejected unless the print wheel is already mounted on the
printer.
For printers that use selectable or programmable character
sets: if the character-set specified is not one defined in the
Terminfo database for the printer [see terminfo(4)], or is not
an alias defined by the administrator, the request is
rejected.

lp(1) (Line Printer Spooling Utilities) lp(1)
When the -d any option is used, the request is printed on any
printer that has the print wheel mounted or any printer that
can select the character set, and that can handle any other
needs of the request.
-t title
Print title on the banner page of the output. The default is
no title.
-T content-type [-r]
Print the request on a printer that can support the specified
content-type. If no printer accepts this type directly, a
filter will be used to convert the content into an acceptable
type. If the -r option is specified, a filter will not be
used. If -r is specified, and no printer accepts the
content-type directly, the request is rejected. If the
content-type is not acceptable to any printer, either directly
or with a filter, the request is rejected.
-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.
-y mode-list
Print this request according to the printing modes listed in
mode-list. The allowed values for mode-list are locally
defined. This option can be used only if there is a filter
available to handle it; otherwise, the print request will be
rejected.
Canceling a Print Request
The cancel command cancels requests for print jobs made with the lp
command. To cancel a job, specify one of the following arguments:
the request-ID for it (as returned by the lp command); the name of
the printer handling it; or the login-ID of the user who requested
it. A printer class is not a valid argument.
Users without special privileges can cancel only requests associated
with their own login IDs.
NOTES
Printers for which requests are not being accepted will not be
considered when the lp command is run and the destination is any.
(Use the lpstat -a command to see which printers are accepting
requests.) On the other hand, if (1) a request is destined for a
class of printers and (2) the class itself is accepting requests,
then all printers in the class will be considered, regardless of
their acceptance status.

For printers that take mountable print wheels or font cartridges, if
you do not specify a particular print wheel or font with the -S
option, whichever one happens to be mounted at the time your request
is printed will be used. Use the lpstat -p printer -l command to see
which print wheels are available on a particular printer, or the
lpstat -S -l command to find out what print wheels are available and
on which printers. For printers that have selectable character sets,
you will get the standard character set if you don't use the -S
option.
