LPADMIN(8) Maintenance Commands and Procedures LPADMIN(8)

NAME

lpadmin - configure the LP print service

SYNOPSIS

lpadmin -p printer {options}


lpadmin -x dest


lpadmin -d [dest]


lpadmin -S print-wheel -T [-A alert-type] [-W minutes]
[-Q requests]

DESCRIPTION

lpadmin configures the LP print service by defining printers and
devices. It is used to add and change printers, to remove printers
from service, to set or change the system default destination, to
define alerts for printer faults, and to mount print wheels.

OPTIONS

The lpadmin command has options for:

o Adding or changing a printer

o Removing a printer destination

o Setting or changing the system default destination

o Setting an alert for a print wheel


The options for each of the above categories are specified in the
following subsections.


Several options support the use of lists. A list might contain, for
example, user names, printers, printer forms, or content types. A
list of multiple items can have the form of either comma-separated
names or have the entire list enclosed by double quotes with a space
between each name. For example, both lists below are acceptable:

one,two,three
"one two three"

Adding or Changing a Printer

The first form of the lpadmin command (lpadmin -p printer {options})
configures a new printer or changes the configuration of an existing
printer. It also starts the print scheduler.


When creating a new printer, one of three options (-v, -U, or -s)
must be supplied. In addition, only one of the following can be
supplied: -e, -i, or -m; if none of these three options is supplied,
the model standard is used. The -h and -l options are mutually
exclusive. Printer and class names must be no longer than 14
characters and must consist entirely of the characters A-Z, a-z, 0-9,
dash (-) and underscore (_). If -s is specified, the following
options are invalid: -A, -e, -F, -h, -i, -l, -M, -m, -o, -U, -v, and
-W.


The following options can appear in any order.

-A alert-type [-W minutes]

The -A option is used to define an alert that informs the
administrator when a printer fault is detected, and periodically
thereafter, until the printer fault is cleared by the
administrator. The alert-types are:

mail
Send the alert message using mail (see mail(1))
to the administrator.


write
Write the message to the terminal on which the
administrator is logged in. If the administrator
is logged in on several terminals, one is chosen
arbitrarily.


quiet
Do not send messages for the current condition.
An administrator can use this option to
temporarily stop receiving further messages
about a known problem. Once the fault has been
cleared and printing resumes, messages are sent
again when another fault occurs with the
printer.


showfault
Attempt to execute a fault handler on each
system that has a print job in the queue. The
fault handler is /etc/lp/alerts/printer. It is
invoked with three parameters: printer_name,
date, file_name. The file_name is the name of a
file containing the fault message.


none
Do not send messages; any existing alert
definition for the printer is removed. No alert
is sent when the printer faults until a
different alert-type (except quiet) is used.


shell-command
Run the shell-command each time the alert needs
to be sent. The shell command should expect the
message in standard input. If there are blank
spaces embedded in the command, enclose the
command in quotes. Notice that the mail and
write values for this option are equivalent to
the values mail user-name and write user-name
respectively, where user-name is the current
name for the administrator. This is the login
name of the person submitting this command
unless he or she has used the su command to
change to another user ID. If the su command has
been used to change the user ID, then the user-
name for the new ID is used.


list
Display the type of the alert for the printer
fault. No change is made to the alert.

When a fault occurs, the printing subsystem displays a message
indicating that printing for a specified printer has stopped and
the reason for the stoppage. The message also indicates that
printing will restart in a few minutes and that you can enter an
enable command if you want to restart sooner than that.

Following a fault that occurs in the middle of a print job, the
job is reprinted from the beginning. An exception to this occurs
when you enter a command, such as the one shown below, that
changes the page list to be printed.

% lp -i request-id -P ...


For a given print request, the presence of multiple reasons for
failure indicate multiple attempts at printing.

The LP print service can detect printer faults only through an
adequate fast filter and only when the standard interface program
or a suitable customized interface program is used. Furthermore,
the level of recovery after a fault depends on the capabilities
of the filter.

If, instead of a single printer, the keyword all is displayed in
an alert, the alert applies to all printers.

If the -W option is not used to arrange fault alerting for
printer, the default procedure is to mail one message to the
administrator of printer per fault. This is equivalent to
specifying -W once or -W 0. If minutes is a number greater than
zero, an alert is sent at intervals specified by minutes.


-c class

Insert printer into the specified class. class is created if it
does not already exist. This option requires the -U dial-info or
-v device options.


-D comment

Save this comment for display whenever a user asks for a full
description of printer (see lpstat(1)). The LP print service does
not interpret this comment.


-e printer

Copy the interface program of an existing printer to be the
interface program for printer. (Options -i and -m must not be
specified with this option.)


-f allow:form-list
-f deny:form-list

Allow or deny the forms in form-list to be printed on printer. By
default no forms are allowed on a new printer.

For each printer, the LP print service keeps two lists of forms:
an ``allow-list'' of forms that can be used with the printer, and
a ``deny-list'' of forms that cannot be used with the printer.
With the -f allow option, the forms listed are added to the
allow-list and removed from the deny-list. With the -f deny
option, the forms listed are added to the deny-list and removed
from the allow-list.

If the allow-list is not empty, only the forms in the list can be
used on the printer, regardless of the contents of the deny-list.
If the allow-list is empty, but the deny-list is not, the forms
in the deny-list cannot be used with the printer. All forms can
be excluded from a printer by specifying -f deny:all. All forms
can be used on a printer (provided the printer can handle all the
characteristics of each form) by specifying -f allow:all.

The LP print service uses this information as a set of guidelines
for determining where a form can be mounted. Administrators,
however, are not restricted from mounting a form on any printer.
If mounting a form on a particular printer is in disagreement
with the information in the allow-list or deny-list, the
administrator is warned but the mount is accepted. Nonetheless,
if a user attempts to issue a print or change request for a form
and printer combination that is in disagreement with the
information, the request is accepted only if the form is
currently mounted on the printer. If the form is later unmounted
before the request can print, the request is canceled and the
user is notified by mail.

If the administrator tries to specify a form as acceptable for
use on a printer that does not have the capabilities needed by
the form, the command is rejected.

Notice the other use of -f, with the -M option, below.

The -T option must be invoked first with lpadmin to identify the
printer type before the -f option can be used.


-F fault-recovery

This option specifies the recovery to be used for any print
request that is stopped because of a printer fault, according to
the value of fault-recovery:

continue
Continue printing on the top of the page where
printing stopped. This requires a filter to wait for
the fault to clear before automatically continuing.


beginning
Start printing the request again from the beginning.


wait
Disable printing on printer and wait for the
administrator or a user to enable printing again.

During the wait, the administrator or the user who
submitted the stopped print request can issue a
change request that specifies where printing should
resume. (See the -i option of the lp command.) If
no change request is made before printing is
enabled, printing resumes at the top of the page
where stopped, if the filter allows; otherwise, the
request is printed from the beginning.


-h

Indicate that the device associated with the printer is
hardwired. If neither of the mutually exclusive options, -h and
-l, is specified, -h is assumed.


-i interface

Establish a new interface program for printer. interface is the
pathname of the new program. (The -e and -m options must not be
specified with this option.)


-I content-type-list

Allow printer to handle print requests with the content types
listed in a content-type-list.

The type simple is recognized as the default content type for
files in the UNIX system. A simple type of file is a data stream
containing only printable ASCII characters and the following
control characters:


Control Char Octal Value Meaning
BACKSPACE 10 Move back one char, except
at beginning of line
TAB 11 Move to next tab stop
LINEFEED 12 Move to beginning of
(newline) next line
FORMFEED 14 Move to beginning of
next page
RETURN 15 Move to beginning of
current line

To prevent the print service from considering simple a valid type
for the printer, specify either an explicit value (such as the
printer type) in the content-type-list, or an empty list. If you
do want simple included along with other types, you must include
simple in the content-type-list.

In addition to content types defined by the print administrator,
the type PostScript is recognized and supported by the Solaris
print subsystem. This includes filters to support PostScript as
the printer content type.

The type any is recognized as a special content type for files.
When declared as the input type for a printer, it signals the
print sub-system not to do any filtering on the file before
sending it to the printer.

Except for simple and any, each content-type name is determined
by the administrator. If the printer type is specified by the -T
option, then the printer type is implicitly considered to be also
a valid content type.


-l

Indicate that the device associated with printer is a login
terminal. The LP scheduler (lpsched) disables all login terminals
automatically each time it is started. (The -h option must not be
specified with this option.)


-m model

Select model interface program, provided with the LP print
service, for the printer. (Options -e and -i must not be
specified with this option.)


-M -f form-name [-a [-o filebreak]] [-t tray-number]]

Mount the form form-name on printer. Print requests that need the
pre-printed form form-name is printed on printer. If more than
one printer has the form mounted and the user has specified any
(with the -d option of the lp command) as the printer
destination, then the print request is printed on the one printer
that also meets the other needs of the request.

The page length and width, and character and line pitches needed
by the form are compared with those allowed for the printer, by
checking the capabilities in the terminfo database for the type
of printer. If the form requires attributes that are not
available with the printer, the administrator is warned but the
mount is accepted. If the form lists a print wheel as mandatory,
but the print wheel mounted on the printer is different, the
administrator is also warned but the mount is accepted.

If the -a option is given, an alignment pattern is printed,
preceded by the same initialization of the physical printer that
precedes a normal print request, with one exception: no banner
page is printed. Printing is assumed to start at the top of the
first page of the form. After the pattern is printed, the
administrator can adjust the mounted form in the printer and
press return for another alignment pattern (no initialization
this time), and can continue printing as many alignment patterns
as desired. The administrator can quit the printing of alignment
patterns by typing q.

If the -o filebreak option is given, a formfeed is inserted
between each copy of the alignment pattern. By default, the
alignment pattern is assumed to correctly fill a form, so no
formfeed is added.

If the -t tray-number option is specified, printer tray tray-
number is used.

A form is ``unmounted'' either by mounting a new form in its
place or by using the -f none option. By default, a new printer
has no form mounted.

Notice the other use of -f without the -M option above.


-M -S print-wheel

Mount the print-wheel on printer. Print requests that need the
print-wheel are printed on printer. If more than one printer has
print-wheel mounted and the user has specified any (with the -d
option of the lp command) as the printer destination, then the
print request is printed on the one printer that also meets the
other needs of the request.

If the print-wheel is not listed as acceptable for the printer,
the administrator is warned but the mount is accepted. If the
printer does not take print wheels, the command is rejected.

A print wheel is ``unmounted'' either by mounting a new print
wheel in its place or by using the option -S none. By default, a
new printer has no print wheel mounted.

Notice the other uses of the -S option without the -M option
described below.


-n ppdfilename

Specify a PPD file for creating and modifying printer queues.
ppdfilename is the full path and file name to the PPD file. Used
in conjunction with the -p, -d, -x, or -S options.


-o option

The -o option defines default printer configuration values given
to an interface program. The default can be explicitly
overwritten for individual requests by the user (see lp(1)), or
taken from a preprinted form description (see lpforms(8) and
lp(1)).

There are several options which are predefined by the system. In
addition, any number of key-value pairs can be defined. See the
section "Predefined Options Used with the -o Option", below.


-P paper-name

Specify a paper type list that the printer supports.


-r class

Remove printer from the specified class. If printer is the last
member of class, then class is removed.


-S list

Allow either the print wheels or aliases for character sets named
in list to be used on the printer.

If the printer is a type that takes print wheels, then list is a
comma or space separated list of print wheel names. These are the
only print wheels considered mountable on the printer. (You can
always force a different print wheel to be mounted.) Until the
option is used to specify a list, no print wheels are considered
mountable on the printer, and print requests that ask for a
particular print wheel with this printer are rejected.

If the printer is a type that has selectable character sets, then
list is a list of character set name ``mappings'' or aliases.
Each ``mapping'' is of the form known-name=alias The known-name
is a character set number preceded by cs (such as cs3 for
character set three) or a character set name from the terminfo
database entry csnm. See terminfo(5). If this option is not used
to specify a list, only the names already known from the terminfo
database or numbers with a prefix of cs is acceptable for the
printer. If list is the word none, any existing print wheel lists
or character set aliases are removed.

Notice the other uses of the -S with the -M option described
above.

The -T option must be invoked first with lpadmin to identify the
printer type before the -S option can be used.


-s system-name

The -s option can be used for both remote or local printers. For
remote printers:

-s system-name[!printer-name] (UUCP format)
-s printer-name@system-name (RCMD format)

Make a remote printer (one that must be accessed through
another system) accessible to users on your system. system-
name is the name of the remote system on which the remote
printer is located it. printer-name is the name used on the
remote system for that printer. For example, if you want to
access printer1 on system1 and you want it called printer2 on
your system:

-p printer2 -s system1!printer1


-p printer2 -s printer1@system1


-s scheme://end-point (URI format)

Make a remote printer (one that must be accessed through
another system) accessible to users on your system. The
supported schemes include lpd and ipp. Specify URI's using
the lpd format as follows:

lpd://server/printers/queue[#Solaris]


URI's using the ipp format are defined by the remote print
server. They are generally of the format:

ipp://server/printers/queue


In either case, server specifies the hostname or IP address
of the remote print server, queue specifies the name of the
print queue on the remote print server, and the optional
#Solaris specifies that the remote print server is a Solaris
server when lpd URI format is being used.

For example:

-p printer -s lpd://server/printers/queue#Solaris
-p printer -s ipp://server/printers/queue


For local printers:

-s "localhost"
Use localhost for the system-name to be used by
the print service. In an environment where the
nodename is variable, print queues are
invalidated when the nodename changes. Using
localhost as the system-name allows print
queues to be maintained across changing
nodenames. The system-name, as used by the
print service, is only set to localhost when
explicitly set with this option; by default,
lpadmin sets system-name to nodename. For
example, if you want to configure a new printer
on the local system, and want it called
printer3:

-p printer3 -s localhost -v device

This option should never be used when creating
name service maps.


-T printer-type-list

Identify the printer as being of one or more printer-types. Each
printer-type is used to extract data from the terminfo database;
this information is used to initialize the printer before
printing each user's request. Some filters might also use a
printer-type to convert content for the printer. If this option
is not used, the default printer-type is unknown. No information
is extracted from terminfo so each user request is printed
without first initializing the printer. Also, this option must be
used if the following are to work: -o cpi, -o lpi, -o width, and
-o length options of the lpadmin and lp commands, and the -S and
-f options of the lpadmin command.

If the printer-type-list contains more than one type, then the
content-type-list of the -I option must either be specified as
simple, as empty (-I ""), or not specified at all.


-tnumber-of-trays

Specify the number of trays when creating the printer.


-u allow:login-ID-list
-u deny:login-ID-list

Allow or deny the users in login-ID-list access to the printer.
By default all users are allowed on a new printer. The login-ID-
list argument can include any or all of the following constructs:

login-ID
a user on any 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 all systems

For each printer, the LP print service keeps two lists of users:
an ``allow-list'' of people allowed to use the printer, and a
``deny-list'' of people denied access to the printer. With the -u
allow option, the users listed are added to the allow-list and
removed from the deny-list. With the -u deny option, the users
listed are added to the deny-list and removed from the allow-
list.

If the allow-list is not empty, only the users in the list can
use the printer, regardless of the contents of the deny-list. If
the allow-list is empty, but the deny-list is not, the users in
the deny-list cannot use the printer. All users can be denied
access to the printer by specifying -u deny:all. All users can
use the printer by specifying -u allow:all.


The -U option allows your print service to access a remote
printer. (It does not enable your print service to access a
remote printer service.) Specifically, -U assigns the
``dialing'' information dial-info to the printer. dial-info is
used with the dial routine to call the printer. Any network
connection supported by the Basic Networking Utilities works.
dial-info can be either a phone number for a modem connection, or
a system name for other kinds of connections. Or, if -U direct is
given, no dialing takes place, because the name direct is
reserved for a printer that is directly connected. If a system
name is given, it is used to search for connection details from
the file /etc/uucp/Systems or related files. The Basic Networking
Utilities are required to support this option. By default, -U
direct is assumed.


-v device

Associate a device with printer. device is the path name of a
file that is writable by lp. Notice that the same device can be
associated with more than one printer.


-v scheme://end-point

Associate a network attached device with printer.

scheme is the method or protocol used to access the network
attached device and end-point is the information necessary to
contact that network attached device. Use of this device format
requires the use of the uri interface script and can only be used
with the smb scheme at this time.

For example:

# lpadmin -p queue -v smb://smb-service/printer -m uri


See the smbspool man page for details.

Removing a Printer Destination

The -x dest option removes the destination dest (a printer or a
class), from the LP print service. If dest is a printer and is the
only member of a class, then the class is deleted, too. If dest is
all, all printers and classes are removed. If there are no remaining
local printers and the scheduler is still running, the scheduler is
shut down.


No other options are allowed with -x.

Setting/Changing the System Default Destination
The -d [dest] option makes dest (an existing printer or class) the
new system default destination. If dest is not supplied, then there
is no system default destination. No other options are allowed with
-d.

Setting an Alert for a Print Wheel

-S print-wheel [-A alert-type] [-W minutes] [-Q requests] -T

The -S print-wheel option is used with the -A alert-type option
to define an alert to mount the print wheel when there are jobs
queued for it. If this command is not used to arrange alerting
for a print wheel, no alert is sent for the print wheel. Notice
the other use of -A, with the -p option, above.

The alert-types are:

mail
Send the alert message using the mail command to
the administrator.


write
Write the message, using the write command, to
the terminal on which the administrator is
logged in. If the administrator is logged in on
several terminals, one is arbitrarily chosen.


quiet
Do not send messages for the current condition.
An administrator can use this option to
temporarily stop receiving further messages
about a known problem. Once the print-wheel has
been mounted and subsequently unmounted,
messages are sent again when the number of print
requests reaches the threshold specified by the
-Q option.


none
Do not send messages until the -A option is
given again with a different alert-type (other
than quiet).


shell-command
Run the shell-command each time the alert needs
to be sent. The shell command should expect the
message in standard input. If there are blanks
embedded in the command, enclose the command in
quotes. Notice that the mail and write values
for this option are equivalent to the values
mail user-name and write user-name respectively,
where user-name is the current name for the
administrator. This is the login name of the
person submitting this command unless he or she
has used the su command to change to another
user ID. If the su command has been used to
change the user ID, then the user-name for the
new ID is used.


list
Display the type of the alert for the print
wheel on standard output. No change is made to
the alert.

The message sent appears as follows:

The print wheel print-wheel needs to be mounted
on the printer(s):
printer(integer1requests) integer2 print requests
await this print wheel.


The printers listed are those that the administrator had earlier
specified were candidates for this print wheel. The number
integer1 listed next to each printer is the number of requests
eligible for the printer. The number integer2 shown after the
printer list is the total number of requests awaiting the print
wheel. It is less than the sum of the other numbers if some
requests can be handled by more than one printer.

If the print-wheel is all, the alerting defined in this command
applies to all print wheels already defined to have an alert.

If the -W option is not given, the default procedure is that only
one message is sent per need to mount the print wheel. Not
specifying the -W option is equivalent to specifying -W once or
-W 0. If minutes is a number greater than zero, an alert is sent
at intervals specified by minutes.

If the -Q option is also given, the alert is sent when a certain
number (specified by the argument requests) of print requests
that need the print wheel are waiting. If the -Q option is not
given, or requests is 1 or any (which are both the default), a
message is sent as soon as anyone submits a print request for the
print wheel when it is not mounted.


PREDEFINED OPTIONS USED WITH THE -o OPTION
A number of options, described below, are predefined for use with -o.
These options are used for adjusting printer capabilities, adjusting
printer port characteristics, configuring network printers, and
controlling the use of banner. The -o also supports an arbitrary
keyword=value format, which is referred to below as an undefined
option.

Adjusting Printer Capabilities

The length, width, cpi, and lpi parameters can be used in conjunction
with the -o option to adjust printer capabilities. The format of the
parameters and their values is as follows:

length=scaled-decimal-number
width=scaled-decimal-number
cpi=scaled-decimal-number
lpi=scaled-decimal-number


The term scaled-decimal-number refers to a non-negative number used
to indicate a unit of size. The type of unit is shown by a
``trailing'' letter attached to the number. Three types of scaled-
decimal-numbers can be used with the LP print service: numbers that
show sizes in centimeters (marked with a trailing c); numbers that
show sizes in inches (marked with a trailing i); and numbers that
show sizes in units appropriate to use (without a trailing letter),
that is, lines, characters, lines per inch, or characters per inch.


The option values must agree with the capabilities of the type of
physical printer, as defined in the terminfo database for the printer
type. If they do not, the command is rejected.


The defaults are defined in the terminfo entry for the specified
printer type. The defaults can be reset by:

lpadmin -p printername -o length=
lpadmin -p printername -o width=
lpadmin -p printername -o cpi=
lpadmin -p printername -o lpi=

Adjusting Printer Port Characteristics

You use the stty keyword in conjunction with the o option to adjust
printer port characteristics. The general form of the stty portion of
the command is:

stty="'stty-option-list'"


The stty-option-list is not checked for allowed values, but is passed
directly to the stty program by the standard interface program. Any
error messages produced by stty when a request is processed (by the
standard interface program) are mailed to the user submitting the
request.


The default for stty is:

stty="'9600 cs8 -cstopb -parenb ixon
-ixany opost -olcuc onlcr
-ocrnl -onocr
-onlret -ofill nl0 cr0 tab0 bs0 vt0 ff0'"


The default can be reset by:

lpadmin -p printername -o stty=

Configuring Network Printers

The dest, protocol, bsdctrl, and timeout parameters are used in
conjunction with the -o option to configure network printers. The
format of these keywords and their assigned values is as follows:

dest=string protocol=string bsdctrl=string \
timeout=non-negative-integer-seconds


These four options are provided to support network printing. Each
option is passed directly to the interface program; any checking for
allowed values is done there.


The value of dest is the name of the destination for the network
printer; the semantics for value dest are dependent on the printer
and the configuration. There is no default.


The value of option protocol sets the over-the-wire protocol to the
printer. The default for option protocol is bsd. The value of option
bsdctrl sets the print order of control and data files (BSD protocol
only); the default for this option is control file first. The value
of option timeout sets the seed value for backoff time when the
printer is busy. The default value for the timeout option is 10
seconds. The defaults can be reset by:

lpadmin -p printername -o protocol=
lpadmin -p printername -o bsdctrl=
lpadmin -p printername -o timeout=

Controlling the Use of the Banner Page

Use the following commands to control the use of the banner page:

lpadmin -p printer -o nobanner
lpadmin -p printer -o banner
lpadmin -p printer -o banner=always
lpadmin -p printer -o banner=never
lpadmin -p printer -o banner=optional


The first and fifth commands (-o nobanner and -o banner=optional) are
equivalent. The default is to print the banner page, unless a user
specifies -o nobanner on an lp command line.


The second and third commands (-o banner and -o banner=always) are
equivalent. Both cause a banner page to be printed always, even if a
user specifies lp -o nobanner. The root user can override this
command.


The fourth command (-o banner=never) causes a banner page never to be
printed, even if a user specifies lp -o banner. The root user can
override this command.

Undefined Options

The -o option supports the use of arbitrary, user-defined options
with the following format:

key=value

Each key=value is passed directly to the interface program. Any
checking for allowed values is done in the interface program.

Any default values for a given key=value option are defined in
the interface program. If a default is provided, it can be reset
by typing the key without any value:

lpadmin -p printername -o key=


lpadmin -p printer -o foo | nofoo

Sets boolean values foo=true | foo=false.

EXAMPLES

In the following examples, prtr can be any name up to 14 characters
and can be the same name as the ping(8) name.

Example 1: Configuring an HP Postscript Printer with a Jet Direct

Network Interface


The following example configures an HP postscript printer with a jet
direct network interface:

-o dest=ping_name_of_prtr:9100 -o protocol=tcp -T PS -I \
postscript
example# enable prtr
example# accept prtr

Example 2: Configuring a Standard Postscript Network Printer

The following example configures a standard postscript network
printer:


example# lpadmin -p prtr -v /dev/null -m netstandard \
-o dest=ping_name_of_prtr -T PS -I postscript
example# enable prtr
example# accept prtr

EXIT STATUS

The following exit values are returned:

0
Successful completion.


non-zero
An error occurred.

NOTES

When using lpadmin to provide access to a remote printer, remote
configuration data is stored in /etc/printers.conf. This data
includes a bsdaddr and a printer-uri-supported attribute. The data in
this file can be shared through the use of a network name service or
replicated across multiple systems. If the data is shared, it is
important to make sure that the bsdaddr and printer-uri-supported
contain hostname information that is correctly resolved on all hosts
sharing this data. Also, the printer-uri-supported is the preferred
means of accessing remote print service. The bsdaddr is supplied for
backward compatibility with Solaris 2.6-10 systems.
