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.
