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.

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.

       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.
