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.

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.
