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.

The following exit values are returned:

zero (0)
    Successful completion.

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.
