ln03of - LN03(S) laser printer filter
/usr/lib/lpdfilters/ln03of [-c] [-nlogin] [-hhost] [-wwidth] [-lnum] [-iindent] [accounting file]
The filter is used to filter text data destined for the LN03 and LN03S 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. The filter translates nroff control sequences for
underlining, superscripting, and subscripting into the correct LN03(S) control sequences.
The filter can be the specified filter in both the of and the if fields in the file. For further information, 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.
The arguments passed to the filter depend on its use. The of filter is called with the following arguments:
ln03of -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
ln03of -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. If the value of the width is greater than 80 the job will be printed in landscape mode
with a slightly smaller font. The length of the page is assumed to be 66 regardless of the length specified. 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 error logging file name.
