SYNOPSIS

lpf -Pprinter -wwidth -llength -xwidth -ylength [ -c ] -Kcontrolfilename -Lbnrname [ -iindent ] [ -Zoptions ] [ -Cclass ] [ -Jjob ] [ -Raccntname ] -nlogin -hHost -Fformat [ -T[crlf,debug] -Dlevel ] [ affile ]

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.
