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 spec‐
       ified 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: Pro‐
       grammer.

       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  fol‐
	      lowing 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 accounting	infor‐
       mation.	The  -i option specifies the amount of indentation to be used.
       The last argument is the name of the accounting file specified from the
       af field in the database.

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

Files
