LPADMIN(1M) Maintenance Commands LPADMIN(1M)


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(1M) 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(4). 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
#Solarisspecifies 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
explicitely 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 againwhen
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(1M) name.

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.
