Name
       lqf - general purpose letter quality filter

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

Description
       The  filter  is	used  to  filter  text	data  destined for a letter quality printer, specifically the lqp02, but will work with any impact
       printer: LP25, LP26, LP27, LA50, LA75, LA100, LA120, LA210, and LG01. The filter allows escape characters and  control  sequences  to  pass
       through	to the printer.  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 completion for each job.

       The filter can handle plain ASCII files and files that have been preprocessed by However, it ignores  escape  sequences	requesting  super-
       scripting and subscripting.

       The  filter can be the specified filter in both the of and the if fields in the file.  For further information, see printcap 5 .  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. This is not  a	problem  for  most  impact
       printers.  For a more detailed discussion on filters see the ``Line Printer Spooler Manual'' in The Supplementary Documents.

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

       lqf -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:

       lqf -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  lpr(1)  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 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 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 logging file name.
