lcg01of(8)lcg01of(8)Namelcg01of - 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 speci‐
fied, 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 undeter‐
mined 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 dae‐
mon, 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 log‐
ging file name.
