Name
       ln03rof, ln03rof_isolatin1, ln03rof_decmcs - LN03R ASCII to PostScript translation filters

Syntax
       /usr/lib/lpdfilters/ln03rof [-c] [-nlogin] [-h host] [-wwidth] [-lnum] [-iindent]  [accounting file]

Description
       The  filter translates ASCII to PostScript, handles the device dependencies of a PostScript printer and performs some accounting functions.
       PostScript printers print documents formatted in the PostScript Page Description Language only.

       The and filters are alternatives to and affect how ASCII documents are printed.	They cause the encoding vectors for ISO Latin1 or DEC  MCS
       to  be  used  instead of the Adobe Standard Encoding Vector described in the LN03R PostScript Programmers Supplement.  The filter uses idle
       cycles to cache the fonts when accessed by the standard encoding vector.  The cached fonts cannot be used by or which means that small jobs
       are slowed down.

       The  filter  is	transparent to documents already formatted in PostScript.  The filter assumes that all other documents are plain ASCII and
       translates them into PostScript.  The decision to translate is based on the first two characters in the document. If  they  are	`%!',  the
       filter  assumes	the  document has already been formatted in PostScript.  If the first two characters are not `%!', the filter assumes that
       the document is plain ASCII and translates it into PostScript.  The filter ensures that the printer receives documents formatted  in  Post-
       Script  only.  The filter maintains accounting information only for documents that it translates.  You specify the accounting file with the
       af field in the file.  For further information, see

       You can specify the filter in both the of and the if fields of the file. The specification of the filter in the	file  determines  how  the
       command affects the printed document. For example:

       o   If you specify it in the of field only and do not suppress banner pages, the filter always translates the document into PostScript.

       o   If  you  specify  it  in  the if field and do not suppress banner pages, the document does not print.  In this case, the banner is sent
	   directly to the printer. Since the banner is not formatted in PostScript, the printer cannot print the document and aborts the job.

       o   If you suppress the banner by including the sh field in or by printing the file using the with the -h option, the document prints  cor-
	   rectly.

       o   You can obtain the best results by specifying the filter in both the of and if fields.

       The ASCII data type for PrintServer software uses the filter.  For more information about how the PostScript translator is invoked, see

       The filter sets a landscape print mode with a smaller font if the width is greater than 80 columns.  The default width for the entry in the
       file is 132.  To print using portrait mode, modify the file to include the following two entries:
       :pl#66:
       :pw#80:
       When printing in portrait mode, if the job page length is greater than 66 a smaller font is used.

       For a more detailed discussion on filters see the ``Line Printer Spooler Manual'' in the 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:

       -llength
	  Specify length values from the pl field in the file .

       -wwidth
	  Specify width values from the pw field in the file.

       The if filter is passed the following arguments:

       -c Print control characters when you use the -l option of to print the file.  (Optional flag).

       -hhost
	  Specify the host name of the job owner.  (Used to record accounting information).

       -iindent
	  Specify the amount of indentation to be used.  The last argument is the name of the accounting file specified from the af field  in  the
	  file.

       -llength
	  Specify  length value from the pl field in the file as it does with the of filter.  Arguments may have different values if the -w and/or
	  -z options of were used to print the file.

       -nlogin
	  Specify the login name of the job owner.  (Used to record accounting information).

       -wwidth
	  Specify width value from the pw field in the file as it does with the of filter.  Arguments may have different values if the	-w  and/or
	  -z options of were used to print the file.  These arguments only affect documents that are translated from ASCII to PostScript.

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

Files
