DESCRIPTION
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.

DIAGNOSTICS
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.
