Name
       ln01of - LN01(S) laser printer filter

Syntax
       /usr/lib/lpdfilters/ln01of [-c] [-nlogin] [-hhost] [-wwidth] [-lnum] [-iindent]	[accounting file]

Description
       The  filter  is used to filter text data destined for the LN01 and LN01S laser printers.  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 and files that have been preprocessed by nroff.  Since nroff only deals with monospaced characters
       this limits the number of fonts that will work effectively. The fonts and font selection files are in The ln01of  filter  translates  nroff
       control	sequences  for underlining into the correct LN01(S) control sequences, but cannot handle superscripting and subscripting.  It will
       pass through any escape or control sequences.

       The filter can be the specified filter in both the of and the if fields in the file, 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 will be sent directly to the printer. If the printer has been left in an undeter-
       mined state the banner page may not print correctly.

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

       ln01of -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:

       ln01of -c -nlogin -hhost -wwidth -lnum -iindent	accounting file
	      The -c flag is optional, and supplied only when control characters 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, 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 information. The -i option specifies the amount of indentation to be used.  The last argu-
	      ment 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 logging file name.
