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:
The name of the printer.
The page width in chars, as given in the :pw field in the printcap
The page length in lines, as given in the :pl field in the print-
The page width in pixels, as given in the :px field in the print-
The page length in pixels, as given in the :py field in the print-
The name of the control file.
The banner name. This is set by the lpr -T option.
The user login name.
The host where the job was submitted.
The job format from the lpr -F option or other option.
These options are optionally set by lpd:
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 print-
-c ignore control characters, set by lpr -b (binary) or -l (literal)
The indentation amount, set by lpr -i indent option.
The class name, set by lpr -C class option.
The job name, set by lpr -J job option.
The name of the accounting file, from printcap information.
Sets debug level. The level must be an integer, a nonzero value
switches debugging on.
Turn LF to CR/LF translation off.
Increment the debug level.
The following exit values are returned:
zero (0) Successful completion.
non-zero (!=0) An error occurred.
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
lpd.conf(5), lpc(8), lpd(8), lpr(1), lpq(1), lprm(1), printcap(5),
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.
