       la75of - LA75 dot matrix printer filter

       /usr/lib/lpdfilters/la75of  [-c]	 [-nlogin]  [-hhost] [-wwidth] [-lnum]
       [-iindent]  [accounting file]

       The filters text data destined for LA75 compact dot matrix printers. It
       handles	the device dependencies of the printer and performs accounting
       functions.  As each job completes, the  filter  writes  the  accounting
       records	to  the file specified by the af field in The can handle plain
       ASCII files as well as files that have been preprocessed by nroff.  The
       filter  correctly  handles  nroff  control  sequences  for underlining,
       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; when of  stops,  the  if	filter
       gains access to the printer and maintains accounting information.

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

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

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

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

       la75of -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 fol‐
	      lowing arguments:

	la75of -c -nlogin -hhost -wwidth -lnum -iindent	 accounting file
	      The -c flag is optional and is supplied only when control	 char‐
	      acters are to be printed. That is, when the -l option of is used
	      to print the file. The -w and -l arguments are the same  as  for
	      the  of  filter but might have different values if the -w and/or
	      -z options of were used to print the file.  The -n and -h	 argu‐
	      ments  specify  the  login  name and host name of the job owner.
	      These arguments are used to record accounting information.   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.

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