Lpf
is a general printer filter. Usually it is used as filter in the
printcap file and is called by lpd.
The -Tcrlf option will suppress translation of LF to CR/LF pairs.
The -Tdebug option will increment the debug level.
The following options passes lpd by default:
-Pprinter
The name of the printer.
-wwidth
The page width in chars, as given in the :pw field in the printcap file
-llength
The page length in lines, as given in the :pl field in the printcap file
-xwidth
The page width in pixels, as given in the :px field in the printcap file
-ylength
The page length in pixels, as given in the :py field in the printcap file
-Kcontrolfilename
The name of the control file.
-Lbnrname
The banner name.
This is set by the lpr -T option.
-nlogin
The user login name.
-hHost
The host where the job was submitted.
-Fformat
The job format from the lpr -F option or other option.
These options are optionally set by lpd:
-Zoptions
Extra options. They are passed from the -Z parameter given on
the lpr command command line and can be interpreted by the filter.
These remaining options can be added
to the filter entry in the printcap file:
-c
ignore control characters, set by lpr -b (binary) or -l (literal) options.
-iindent
The indentation amount, set by lpr -i indent option.
-Cclass
The class name, set by lpr -C class option.
-Jjob
The job name, set by lpr -J job option.
-Raccntname
The name of the accounting file, from printcap information.
-Dlevel
Sets debug level. The level must be an integer, a nonzero value
switches debugging on.
-Tcrlf
Turn LF to CR/LF translation off.
-Tdebug
Increment the debug level.
EXIT STATUS
The following exit values are returned:
zero (0)
Successful completion.
non-zero (!=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
/etc/printcap 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.
