LPF(1) lpf filter LPF(1) NAME lpf - general printer filter SYNOPSIS lpf -Pprinter -wwidth -llength -xwidth -ylength [ -c ] -Kcontrolfile- name -Lbnrname [ -iindent ] [ -Zoptions ] [ -Cclass ] [ -Jjob ] [ -Rac- cntname ] -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 print- cap file -xwidth The page width in pixels, as given in the :px field in the print- cap file -ylength The page length in pixels, as given in the :py field in the print- cap 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 print- cap 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. FILES The files used by LPRng are set by values in the printer configuration file. The following are a commonly used set of default values. /usr/local/etc//lpd.conf LPRng configuration file ${HOME}/.printcap user printer description file /etc/printcap printer description file /usr/local/etc//lpd.perms permissions /var/run/lpd lock file for queue control /var/spool/lpd spool directories /var/spool/lpd/QUEUE/control queue control /var/spool/lpd/QUEUE/log trace or debug log file /var/spool/lpd/QUEUE/acct accounting file /var/spool/lpd/QUEUE/status status file SEE ALSO lpd.conf(5), lpc(8), lpd(8), lpr(1), lpq(1), lprm(1), printcap(5), lpd.perms(5), pr(1), lprng_certs(1), lprng_index_certs(1). AUTHOR Patrick Powell <papowell@lprng.com>. 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.
