lp, cancel -- send/cancel print requests
Synopsis
lp [print-options] [files]
lp -i request-ID print-options
cancel [request-IDs] [printers]
cancel -u login-IDs [printers]
Description
The first form of the lp command arranges for the named files and
associated information (collectively called a request) to be printed.
If filenames are not specified on the command line, the standard input
is assumed. The standard input may be specified along with named files
on the command line by listing the filenames and specifying - for the
standard input. The files will be printed in the order in which they
appear on the command line. lp processes supplementary code set
characters according to the locale specified in the LC_CTYPE
environment variable (see LANG on environ(5)), except as noted under
the -t option below.
The LP print service associates a unique request-ID with each request
and displays 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, and lpstat(1) for information about checking the status of a
print request.
The second form of lp is used to change the options for a request
submitted previously. The print request identified by the request-ID
is changed according to the print-options specified with this command.
The print-options available are the same as those with the first form
of the lp 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).
The cancel command allows users to cancel print requests previously
sent with the lp command. The first form of cancel permits
cancellation of requests based on their request-ID. The second form of
cancel permits cancellation of requests based on the login-ID of their
owner.
Sending a print request
The first form of the lp command is used to send a print request
either to a particular printer or to any printer capable of meeting
all requirements of the print request.
Options to lp must always precede filenames, but may be specified in
any order. The following options are available for lp:
-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 option is not specified, 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. If dest is
any, then the request will be printed on any printer that can
handle it. 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
LPDEST is not set, then dest is taken from the environment
variable PRINTER. If PRINTER is not set, a default destination
(if one exists) for the computer system is used. If no system
default is set and -T is used, dest will be selected on the
basis of content-type specified with the -T option [see the
description of -T]. 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 defined below:
hold
Do not 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. If the Auditing
Utilities are installed, the use of this option is an
auditable event.
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. If the Auditing Utilities
are installed, the use of this option is an auditable
event. The -i option (followed by a request-ID) must be
used whenever this argument is specified.
immediate
(Available only to LP administrators) Print the request
next. If more than one request is assigned immediate, the
most recent request will be printed first. If another
request is currently printing, it must be put on hold to
allow this immediate request to print.
-L locale-name
Specify locale-name as the locale to use with this print
request. By default, locale-name is set to the value of
LC_CTYPE. If LC_CTYPE is not set, locale-name defaults to the C
locale.
-m
Send mail (see mail(1)) after the files have been printed. By
default, mail is not sent upon normal completion of the print
request.
-n number
Print number copies of the output. The default is one copy.
-o options
Specify printer-dependent options. Several such options may be
collected by specifying the -o keyletter more than once (that
is, -o option[1] -o option[2] ... -o option[n]), or by
specifying a list of options with one -o keyletter enclosed in
double quotes and separated by spaces (that is, -o "option[1]
option[2] . . . option[n]").
nobanner
Do not print a banner page with this request. The
administrator can disallow this option at any time. This
option is not supported by printers configured to use the
B2 interface.
nofilebreak
Do not insert a form feed between the files given, if
submitting a job to print more than one file. This option
is not supported by printers configured to use the PS
(PostScript) interface.
length=scaled-decimal-number
Print this request with pages scaled-decimal-number long.
A scaled-decimal-number is an optionally scaled decimal
number that gives a size in lines, characters, 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 characters; 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 may not be used
with the -f option and is not supported by the PS
(PostScript) or B2 interface.
width=scaled-decimal-number
Print this request with pages scaled-decimal-number wide.
(See the explanation of scaled-decimal-numbers in the
discussion of length, above.) This option may not be used
with the -f option and is not supported by the PS
(PostScript) or B2 interface.
lpi=scaled-decimal-number
Print this request with the line pitch set to
scaled-decimal-number. (See the explanation of
scaled-decimal-numbers in the discussion of length,
above.) This option may not be used with the -f option and
is not supported by the PS (PostScript) or B2 interface.
cpi=pica|elite|compressed
Print this request with the character pitch set to pica
(representing 10 characters per inch), elite (representing
12 characters per inch), or compressed (representing as
many characters per inch as a printer can handle). There
is not a standard number of characters per inch for all
printers; see the terminfo(4) database for the default
character pitch for your printer. This option may not be
used with the -f option and is not supported by the PS
(PostScript) or B2 interface.
stty=stty-option-list
A list of options valid for the stty command; enclose the
list with single 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 ranges 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 (highest priority) to 39
(lowest priority). If a priority is not specified, the default
for the print service is used, as assigned by the system
administrator. A priority limit may be assigned to individual
users by the system administrator. If the Auditing Utilities
are installed, the use of this option is an auditable event.
-R
Remove file(s) after submitting the print request. Use this
option with caution.
-r
See ``-T content-type [-r]'' below.
-s
Suppress the ``request id is ...'' message.
-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.
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 all other
needs of the request.
-t title
Print title on the banner page of the output. The default is no
title. Enclose title in quotes if it contains blanks.
Supplementary code set characters specified in title are not
printed correctly (see banner(1)).
-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 but 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.
In addition to ensuring that no filters will be used, the -r
option will force the equivalent of the -o 'stty=-opost'
option.
-w
Write a message on the user's terminal after the files have
been printed. If the user is not logged in, or if the printer
resides on a remote system, then mail will be sent instead. Be
aware that messages may be sent to a window other than the one
in which the command was originally entered.
-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 may be used only if there is a filter
available to handle it; otherwise, the print request will be
rejected.
The following list describes the mode-list options:
-y reverse
Reverse the order in which pages are printed. This filter
option is not supported by the LP Print Service.
-y landscape
Change the orientation of a physical page from portrait to
landscape.
-y x=number,y=number
Change the default position of a logical page on a
physical page by moving the origin.
-y group=number
Group multiple logical pages on a single physical page.
-y magnify=number
Change the logical size of each page in a document.
-o length=number
Select the number of lines in each page of the document.
-P number
Select, by page numbers, a subset of a document to be
printed.
-n number
Print multiple copies of a document.
Canceling a print request
The cancel command cancels requests for print jobs made with the lp
command. The first form allows a user to specify one or more
request-IDs of print jobs to be canceled. Alternatively, the user can
specify one or more printers, on which only the currently printing job
will be canceled if it is the user's job.
The second form of cancel cancels all jobs for users specified in
login-IDs. In this form the printers option can be used to restrict
the printers on which the users' jobs will be canceled. Note that in
this form, when the printers option is used, all jobs queued by the
users for those printers will be canceled. A printer class is not a
valid argument.
A user without special privileges can cancel only requests that are
associated with his or her own login ID; To cancel a request, a user
issues the command:
cancel -u login-ID [printer]
This command cancels all print requests associated with the login-ID
of the user making the request, either on all printers (by default) or
on the printer specified.
Administrative users with the appropriate privileges can cancel jobs
submitted by any user by issuing the following types of commands:
cancel -u "login-ID-list"
Cancels all requests (on all relevant printers) by the
specified users, including those jobs currently being printed.
Double quotes must be used around login-ID-list if the list
contains blanks. The argument login-ID-list may include any or
all of the following constructs:
login-ID
a user on the local system
system-name!login-ID
a user on system system-name
system-name!all
all users on system system-name
all!login-ID
a user on all systems
all
all users on the local system
all!all
all users on all systems
Note that a remote job can be canceled only if it originated on
the client system; that is, a server system can cancel jobs
that came from a client, and a client system can cancel jobs it
sent to a server.
The exception to this is when the bsd printer protocol is being
used and the client has been marked as ``trusted'' in
/etc/lp/Systems. This allows the root user on a trusted client
to cancel requests originating with other clients. See
lpsystem(1M) for more information.
cancel -u "login-ID-list" printer-1
printer-2 printer-n" Cancels all requests by the specified
users for the specified printers, including those jobs
currently being printed. (For a complete list of printers
available on your system, execute the lpstat -p command.)
In any of these cases, the cancellation of a request that is currently
printing frees the printer to print the next request.
If the Auditing Utilities are installed, the use of this command is an
auditable event.
Downloading type 1 postScript fonts to postScript printers
The UnixWare Desktop has a feature allowing the installation of Type 1
scalable outline fonts for use with applications. These fonts may be
downloaded to PostScript printers if the application generates
PostScript output that uses them. Filtering of output does not
automatically occur when the printer accepts the content type of the
request (specified by the -T option) directly. For Postscript requests
with content type PS, downloading of fonts will not take place. Use
content type postscript or post if automatic font downloading is
required. The lp command can handle this automatically using the
filter named download. For more information, see download(1).

Notices
Printers for which requests are not being accepted will not be
considered when the destination is any. (Use the lpstat -a command to
see which printers are accepting requests.) However, if a request is
destined for a class of printers and 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. The lpstat -p printer -l command is used to
see which print wheels are available on a particular printer. The
lpstat -S -l command is used to see what print wheels are available
and on which printers. Without the -S option, the standard character
set is used for printers that have selectable character sets.
If you experience problems with jobs that usually print but on
occasion do not print, check the physical connections between the
printer and your computer. If you are using an automatic data switch
or an A/B switch, try removing it and see if the problem clears.
Earlier versions of the UNIX^® system may issue warnings about
unrecognized options (such as the locale= or flist= options), when
processing print requests from remote systems running a more recent
version of the LP Print Server. The request will be printed normally,
however.
Administrators with appropriate privileges can suppress these warnings
by adding the following two lines to the section annotated as ``adding
simple options,'' in the printer interface program used by the printer
issuing the warnings.
locale=*) ;;
flist=*) ;;
(Printer interface programs are found in the /usr/lib/lp/model
directory.) An example of how to do this can be found in the standard
interface program.
