lpf(8)							      System Manager's Manual							    lpf(8)

Name
       lpf - general purpose line printer filter

Syntax
       /usr/lib/lpdfilters/lpf [-c] [-nlogin] [-hhost] [-wwidth] [-lnum] [-iindent]  [accounting file]

Description
       The  filter  handles text data destined for impact printers: LP25, LP26, LP27, LA50, LA75, LA100, LA120, LA210, LG01.  The filter regulates
       the device dependencies of the printers and performs accounting functions.  When the print job is done, writes accounting  records  to  the
       file specified by the af field in /etc/printcap.

       The  filter  can  handle  plain	ASCII  files  as well as files that have been preprocessed by nroff.  However, it ignores escape sequences
       requesting superscripting and subscripting.

       You can specify the filter in both the of and the if fields of the file.  For further information, see When you specify both fields, the of
       filter  prints the banner page only, then stops.  The if filter then gains access to the printer. The if filter maintains accounting infor-
       mation.

       If you specify the of field only, it prints the banner page then stops and restarts to maintain accounting information.

       If you specify the if field only, it sends the banner page directly to the printer.  This is not a problem for most impact printers.

       For a more detailed discussion on filters see the ``Line Printer Spooler Manual'' in the ULTRIX Supplementary Documents, Volume 2: Program-
       mer.

       The arguments passed to the filter depend on its use.  The of filter is called with the following arguments:

       lpf -wwidth -llength
	      The  width  and  length values come from the pw and pl fields in the database. The if (or restart of) filter is passed the following
	      arguments:

       lpf -c -nlogin -hhost -wwidth -lnum -iindent  accounting file

       The -c flag is optional and supplied only when control characters are to be printed; when the -l option of is used to print the	file.  The
       -w  and -l arguments are the same as for the of filter, however, they may have different values if the -w and/or -z options of were used to
       print the file.	The -n and -h arguments specify the login name and host name of the job owner. These arguments are used to record account-
       ing  information. The -i option specifies the amount of indentation to be used. The last argument is the name of the accounting file speci-
       fied from the af field in the database.

Diagnostics
       The lf field (default /dev/null) in the database specifies error logging file name.

Name
       lcg01of - LCG01 Color Printing System Filter

Syntax
       /usr/lib/lpdfilters/lcg01of [-c] [-nlogin] [-hhost] [-wwidth] [-lnum] [-iindent]  [accounting file]

Description
       The  filter  is	used  to filter text data destined for the LCG01 Color Printing System.  The filter handles the device dependencies of the
       printers and performs accounting functions.  Accounting records are written to the file specified by the af field in at the time of comple-
       tion for each job.

       The  filter  can  handle plain ASCII files, nroff files, and sixel files. The printer also supports the following graphic protocols: ReGIS,
       NAPLPS, and GIDIS. To print using these protocols, the xf(8) filter should be invoked using the lpr -x option.  The filter translates nroff
       control sequences for underlining, superscripting, and subscripting into the correct LCG01 control sequences.

       The  filter  can  be  the specified filter in both the of and the if fields in the file.  For further information, see When both fields are
       specified, the of filter is used only to print the banner page.	It is then stopped to allow the if filter access to the  printer.  The	if
       filter maintains accounting information.

       If the of field is the only one specified, the filter is used to print the banner page.	It is then stopped and restarted.  This allows the
       of filter to be used to maintain accounting information.

       If the if field is the only one specified, the banner page is sent directly to the printer. If the printer has been left in an undetermined
       state, the banner page may not print correctly.

       The  best  results  are obtained when the filter is specified in both the of and if fields.  For a more detailed discussion on filters, see
       the ``Line Printer Spooler Manual'' in the ULTRIX Supplementary Documents, Volume 2: Programmer.

Options
       The filter ignores the arguments passed to it by the line printer daemon, lpd(8).  The of filter is called with the following arguments:

       lcg01of -wwidth -llength
	      The width and length values come from the pw and pl fields in the database.

       The if (or restarted of) filter is passed the following arguments:

       lcg01of -c -nlogin -hhost -wwidth -lnum -iindent  accounting file

Diagnostics
       The lf field (default /dev/null) in the database specifies error logging file name.

Files
