The LPRng
lpr
client supports an lp interface when invoked with the
lp
program name.
This is usually done by making a symbolic link to the
lpr program with the name
lp.
This is similar to the
ex(1)
and
vi(1)
programs.
The supported form of the lp command
arranges for the named file(s) and associated information
(collectively called a
request)
to be printed.
If no file names are specified on the command line,
the standard input is assumed.
The standard input may be specified
along with a named file(s)
on the command line by listing the file name(s)
and specifying `-' (dash)
for the standard input.
The files will be printed
in the order in which they appear on the shell command line.
The
LP
print service
associates a unique request-ID
with each request
and displays it on the standard output.
The job number portion or full request-ID can be used later with
cancel(1)
or
lprm(1)
when canceling a job or when determining its status.
See
cancel(1)
and
lprm(1)
for details about canceling a request,
and
lpstat(1)
and
lpq(1)
for information about checking the status of a print request.
OPTIONS
Options to
lp
always precede any file names,
but may be specified in any order.
The following options are available for
lp:
-A
Use authenticated transfer.
Note that this is not a standard
lp(1)
option but has been added for compatibilty with LPRng.
The authentication type is set by the value of the AUTH environment variable.
-B
Process jobs using filters specified in the printcap information.
The filter output is combined into a single file and sent to the print spooler.
-c
Make a copy
of the
file
before printing.
(This has no effect as LPRng always sends
jobs immediately to the remote server for printing.)
-d dest
The print queue or printer to be used.
By default,
the destination printer
is taken from
the command line
dest
value,
then
the environment variables
PRINTER,
LPDEST,
NPRINTER,
NGPRINTER,
then first entry in the printcap information,
and and finally the default_printer entry from the
configuration file,
and then the compile time default.
-f form-name
Print the request on the form
form-name.
This sets the job class to
form-name
and is similar to the lpr -C option.
-G
Process jobs using filters specified in the printcap information.
The filter output for individual files is sent to the print spooler.
-H special-handling
These options are ignored.
-m
Send mail (see
mail(1))
after the files have been printed.
The mail address is taken from the USER enviroment
variable.
By default, no mail is sent
upon normal completion of the print request.
-n number
Print
number
copies (default is
1)
of the output.
-o option
Specify printer-dependent
options.
Several such
options
may be collected by specifying
the
-o
keyletter more than once
(-o $option sub 1$
-o $option sub 2$ ... -o $option sub n$),
or by specifying
the -o keyletter followed by
a list of options
enclosed in double quotes
(that is, -o "$option sub 1$
$option sub 2$ ... $option sub n$").
The following options have a immediate effect;
other options are passed as a
Z
line entry in the control file,
i.e. - as an
lpr(1)-Z
option.
nobanner
Do not print a banner page with this request.
This is the same as the
lpr(1)-h
(no header) option.
width=number
Print this request with page-width set to
number.
This is the same as the
lpr(1)-w width
option.
-P page-list
Print the pages specified in page-list.
This option is ignored.
-p
Enable notification on completion of the print request.
This option is ignored.
-q priority-level
Assign this request priority-level in the printing queue.
The values of priority-level range from
0,
the highest priority, to
25,
the 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.
The numerical values are translated to corresponding letter
priority values.
-s
Suppress messages from lp
such as those that begin with "request id is..."
-S character-set
-S print-wheel
Print this request using the specified character-set
or print-wheel.
The options are passed as an
lpr(1)-Z
option.
-t title
Print
title
on the banner page of the output.
If
title
is not supplied the name of the file is printed on the banner
page.
Enclose title in quotes if it contains blanks.
-T content-type [-r]
Print the request on a printer that can support
the specified content-type.
The
content-type
is passed as an
lpr(1)-Z
option.
-w
Write a message on the user's terminal after the
files
have been printed.
This option is ignored.
-X path
Filter individual job files using the specified program and send
the filter output to the print spooler.
-y mode-list
Print this request
according to the printing modes listed in mode-list.
The
mode-list-type
is passed as an
lpr(1)-Z
option.
-D debug-optios
A list of debug options for the program.
These can be a number (debug level) or keyword and level (flag),
such as 9, network, network+2, etc.
OPERANDS
The following operands are supported by
lp:
file
A path name of a file to be output.
If no
file
operands are specified,
or if a
file
operand is
-,
the standard input will be used.
The
-
option must be last in the list.
PRINTCAP INFORMATION
The printer names and other information is obtained by using a printcap
file or some other database.
The ${HOME}/.printcap
file can be used to specify user level options and configuration
information.
See
printcap(5)
for more information.
ENVIRONMENT
By default,
the destination printer
is taken from
the command line
dest
value,
then
the environment variables
PRINTER,
LPDEST,
NPRINTER,
NGPRINTER,
then first entry in the printcap information,
and and finally the default_printer entry from the
configuration file,
and then the compile time default.
EXIT STATUS
The following exit values are returned:
zero (0)
Successful completion
nonzero (!= 0)
An error occurred.
FILES
The files used by LPRng are set by values in the
printer configuration file.
The following are a commonly used set of default values.
/etc/lpd.conf LPRng configuration file
${HOME}/.printcap user printer description file
/etc/printcap system printer description file
/etc/lpd.perms printer permissions
/var/spool/printer* spool directories
/var/spool/printer*/printer lock file for queue control
/var/spool/printer*/control.printer queue control
/var/spool/printer*/active.printer active job
/var/spool/printer*/log.printer log file
Most of the diagnostics are self explanatory.
If you are puzzled over the exact cause of failure,
set the debugging level on (-D5) and run again.
The debugging information will
help you to pinpoint the exact cause of failure.
