NAME
lpadmin - configure the LP print service
SYNOPSIS
lpadmin -p printer options
lpadmin -x dest
lpadmin -d [dest]
lpadmin -S print-wheel -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 the service, to set or change the system default destination, to
define alerts for printer faults, and to mount print wheels.
Adding or Changing a Printer
The first form of the lpadmin command (lpadmin -p printer options) is
used to configure a new printer or to change the configuration of an
existing printer. The following options may appear in any order.
-A alert-type [-W minutes]
The -A option is used to define an alert to inform 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 via mailx [see mailx(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 will again be sent when another fault occurs
with the printer.
none Do not send messages; any existing alert definition for
the printer will be removed. No alert will be 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 blanks embedded in the
command, enclose the command in quotes. Note that the
mail and write values for this option are equivalent to
the values mailx user-name and write user-name
respectively, where user-name is the current name for
Licensed material--property of copyright holder(s) 1
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
the administrator. This will be 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.
The message sent appears as follows:
The printer printer has stopped printing for the reason given
below. Fix the problem and bring the printer back on line.
Printing has stopped, but will be restarted in a few minutes;
issue an enable command if you want to restart sooner. Unless
someone issues a change request
lp -i request-id -P ...
to change the page list to print, the current request will be
reprinted from the beginning.
The reason(s) it stopped (multiple reasons indicate reprinted
attempts):
reason
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 the printer is all, the alerting defined in this command
applies to all existing 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 will be sent at intervals specified by minutes.
-c class
Insert printer into the specified class. Class will be created
if it does not already exist. (see -r to remove a printer from
a class)
-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 printer1
Copy the interface program of an existing printer1 to be the
interface program for printer. (Options -i and -m may not be
specified with this option.)

-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
will resume at the top of the page where stopped, if the
filter allows; otherwise, the request will be printed
from the beginning.
-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 may be used with the printer,
and a ``deny-list'' of forms that may not 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 may
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 may not 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.

lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
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 doesn't have the capabilities needed by
the form, the command is rejected.
Note the other use of -f, with the -M option, below.
-H strms_mod
Pushes STREAMS modules specified by the strms_mod argument (one
or more comma separated modules) onto the stream before printing
is begun. To use the currently configured modules for the
stream specify -H keep. Specifying -H none will cause no
modules to be used. If -H default is given, then the default
modules for the lp print services are used, which is currently
the ldterm module. If no option is given, then keep is used.
This option is valid only with local printers.
-h Indicate that the device associated with the printer is
hardwired. If neither of the mutually exclusive options, -h and
-l, is specified, this option is assumed.
-I content-type-list
Allow printer to handle print requests with the content types
listed in a content-type-list. If the list includes names of
more than one type, the names must be separated by commas or
blank spaces. (If they are separated by blank spaces, the
entire list must be enclosed in double quotes.)
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 Character Octal Value Meaning
---------------------------------------------------------------------
backspace 108 move back one character, except
at beginning of line
tab 118 move to next tab stop
linefeed (newline) 128 move to beginning of next line
form feed 148 move to beginning of next page
carriage return 158 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.
Except for simple, each content-type name is freely determined
Licensed material--property of copyright holder(s) 4
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
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.
-i interface
Establish a new interface program for printer. Interface is the
pathname of the new program. (The -e and -m options may not be
specified with this option.)
-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
may not be specified with this option.)
-M -f form-name [-a [-o filebreak]]
Mount the form form-name on printer. Print requests that need
the pre-printed form form-name will be 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 will be 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.
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.
Note the other use of -f without the -M option above.

lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
-M -S print-wheel
Mount the print-wheel on printer. Print requests that need the
print-wheel will be 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 will be 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.
Note the other uses of the -S option without the -M option
described below.
-m model
Select model interface program, provided with the LP print
service, for the printer. (Options -e and -i may not be
specified with this option.)
-o printing-option
Each -o option in the list below is the default given to an
interface program if the option is not taken from a preprinted
form description or is not explicitly given by the user
submitting a request [see lp(1)]. The only -o options that can
have defaults defined are listed below.
length=scaled-decimal-number
width=scaled-decimal-number
cpi=scaled-decimal-number
lpi=scaled-decimal-number
stty='stty-option-list'
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 first four default 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 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
Licensed material--property of copyright holder(s) 6
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
user submitting the request.
For each printing option not specified, the defaults for the
following attributes are defined in the terminfo entry for the
specified printer type.
length
width
cpi
lpi
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'
You can set any of the -o options to the default values (which
vary for different types of printers), by typing them without
assigned values, as follows:
length=
width=
cpi=
lpi=
stty=
-o nobanner
Allow a user to submit a print request specifying that no banner
page be printed.
-o banner
Force a banner page to be printed with every print request, even
when a user asks for no banner page. This is the default; you
must specify -o nobanner if you want to allow users to be able
to specify -o nobanner with the lp command.
-r class
Remove printer from the specified class. If printer is the last
member of class, then class will be removed. (see -c to add
printers to a class)
-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. (Enclose
the list with quotes if it contains blanks.) These will be the
only print wheels considered mountable on the printer. (You can
always force a different print wheel to be mounted, however.)
Until the option is used to specify a list, no print wheels will
be considered mountable on the printer, and print requests that
ask for a particular print wheel with this printer will be
rejected.
If the printer is a type that has selectable character sets,
then list is a comma or blank separated list of character set
name ``mappings'' or aliases. (Enclose the list with quotes if
Licensed material--property of copyright holder(s) 7
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
it contains blanks.) 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
will be acceptable for the printer.
If list is the word none, any existing print wheel lists or
character set aliases will be removed.
Note the other uses of the -S with the -M option described
above.
-s system-name[!printer-name]
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 running DG/UX 5.4x on which the remote
printer is located; it must be listed in the systems table
(/etc/lp/Systems). Printer-name is the name used on the remote
system for that printer. See the -U option for accessing
printers on systems running pre-DG/UX 5.4x. For example, if you
want to access printer1 on system1 and you want it called
printer2 on your system, enter -p printer2 -s system1!printer1
-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 may also use
a printer-type to convert content for the printer. If this
option is not used, the default printer-type will be unknown; no
information will be extracted from terminfo so each user request
will be 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.
-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 may include any or all of the following
constructs:
login-ID a user on any system
Licensed material--property of copyright holder(s) 8
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
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 may
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 may not use the printer. All users can be
denied access to the printer by specifying -u deny:all. All
users may use the printer by specifying -u allow:all.
-U dial-info
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 will
work. 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 will take 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.
-U printer-name@system-name
The -U option may also be used to make available a printer that
runs on a pre-DG/UX 5.4x system. This is similar to the -s
system-name option which makes printers available on remote
systems that are DG/UX 5.4x systems.
-v device
Associate a device with printer. Device is the path name of a
file that is writable by lp. Note that the same device can be
associated with more than one printer.
Restrictions
When creating a new printer, one of three options (-v, -U, or -s must
Licensed material--property of copyright holder(s) 9
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
be supplied. In addition, only one of the following may 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 may be no longer than 14 characters and must
consist entirely of the characters A-Z, a-z, 0-9 and _ (underscore).
If -s is specified, the following options are invalid: -A, -e, -F,
-h, -i, -l, -M, -m, -o, -U, -v, and -W.
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 will be deleted, too. If dest
is all, all printers and classes are removed. 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]
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 will be sent for the print wheel.
Note the other use of -A, with the -p option, above.
The alert-types are:
mail Send the alert message via the mailx command to the
administrator.
write Write the message, via 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 will again be sent 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
Licensed material--property of copyright holder(s) 10
lpadmin(1M) DG/UX 5.4.2 lpadmin(1M)
command, enclose the command in quotes. Note 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 will be 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 (integer1 requests)
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 will be 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 will be 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
will be sent at intervals specified by minutes.
If the -Q option is also given, the alert will be 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 the word 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.
