       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:

            The name of the printer.

            The page width in chars, as given in the :pw field in the printcap

            The page length in lines,  as  given  in  the  :pl  field  in  the
            printcap file

            The  page  width  in  pixels,  as  given  in  the :px field in the
            printcap file

            The page length in pixels, as  given  in  the  :py  field  in  the
            printcap file

            The name of the control file.

            The banner name.  This is set by the lpr -T option.

            The user login name.

            The host where the job was submitted.

            The job format from the lpr -F option or other option.

       These options are optionally set by lpd:

            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)

            The indentation amount, set by lpr -i indent option.

            The class name, set by lpr -C class option.

            The job name, set by lpr -J job option.

            The name of the accounting file, from printcap information.

            Sets debug level. The level must be an integer,  a  nonzero  value
            switches debugging on.

            Turn LF to CR/LF translation off.

            Increment the debug level.


       The following exit values are returned:

       zero (0)       Successful completion.

       non-zero (!=0) An error occurred.


       The  files used by LPRng are set by values in the printer configuration
       file.  The following are a commonly used set of default values.
       //etc/lprng/lpd.conf                         LPRng configuration file
       ${HOME}/.printcap                            user printer description file
       //etc/printcap                               printer description file
       //etc/lprng/lpd.perms                        permissions
       /var/run/lprng/lpd                           lock file for queue control
       /var/spool/lpd                               spool directories

       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.
