Name
lcg01of - LCG01 Color Printing System Filter
Syntax
/usr/lib/lpdfilters/lcg01of [-c] [-nlogin] [-hhost] [-wwidth] [-lnum] [-iindent] [accounting file]
Description
The filter is used to filter text data destined for the LCG01 Color Printing System. 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, nroff files, and sixel files. The printer also supports the following graphic protocols: ReGIS,
NAPLPS, and GIDIS. To print using these protocols, the xf(8) filter should be invoked using the lpr -x option. The filter translates nroff
control sequences for underlining, superscripting, and subscripting into the correct LCG01 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 is sent directly to the printer. If the printer has been left in an undetermined
state, the banner page may not print correctly.
The best results are 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 filter ignores the arguments passed to it by the line printer daemon, lpd(8). The of filter is called with the following arguments:
lcg01of -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:
lcg01of -c -nlogin -hhost -wwidth -lnum -iindent accounting file
Diagnostics
The lf field (default /dev/null) in the database specifies error logging file name.
