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 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:
LPRng LPRng-3.6.14beta28 1
LPF(1)LPF(1)-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 infor-
mation.
-Dlevel
Sets debug level. The level must be an integer, a
nonzero value switches debugging on.
-Tcrlf
Turn LF to CR/LF translation off.
-TNNN
NNN is an integer in C format. The corresponding
character is appended to the end of a line (LF, CR,
or CR/LF). This can be done to force a different
form of CR/LF translation.

configuration file. The following are a commonly used set

LPF(1)LPF(1)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.
