grolbp
is a driver for
groff
that produces output in CAPSL and VDM format suitable for Canon LBP-4 and
LBP-8 printers.
For compatibility with grolj4 there is an additional drawing command
available:
\D'R dh dv'
Draw a rule (i.e. a solid black rectangle), with one corner at the current
position, and the diagonally opposite corner at the current position
+(dh,dv).
OPTIONS

argument; on the other hand, there must be whitespace and/or an equal sign
(`=') between a long-name option and its argument.

TYPEFACES
The driver supports the Dutch, Swiss and Swiss-Narrow scalable typefaces,
each one in the Regular, Bold, Italic and Bold-Italic styles.
Additionally, the Courier and Elite monospaced typefaces at the sizes 8 and
12 points (for Courier) resp. 8 and 10 points (for Elite) are supported,
each one in the Regular, Bold and Italic styles.
The following chart summarizes the font names you can use to access these
fonts:

PAPER SIZES
The paper size can be set in the
DESC
file or with command line options to
grolbp.
If the paper size is specified both ways, the command line options take
precedence over the contents of the
DESC
file (this applies to the page orientation too).
See
groff_font(1)
how to set the paper dimensions in the
DESC
file.
To set the paper size in the command line, add
-p paper-size
or
--papersize=paper-size
to the other
grolbp
options, where
paper-size
is in the same format as in the
DESC
file.
If no paper size is specified in the
DESC
file or the command line, a default size of A4 is used.
PAGE ORIENTATION
As with the page size, the orientation of the printed page
(portrait
or
landscape)
can be set in the
DESC
file or with command line options.
It is also case insensitive.
To set the orientation in the
DESC
file, insert a line with the following content:
orientation
[portrait|landscape]
Only the first valid orientation command in the
DESC
file is used.
To set the page orientation with command line options you can use the
-o
or
--orientation
option with the same parameters
(portrait
or
landscape)
as in the
DESC
file.
Or you can use the
-l
option to force the pages to be printed in landscape.
FONT FILE FORMAT
In addition to the usual commands described in
groff_font(5),
grolbp
provides the command
lbpname
which sets the font name sent to the printer when requesting this font.
The syntax of this command is:
lbpnameprinter_font_name
*
For bitmapped fonts,
printer_font_name
has the form
Nlabase_fontnameralafont_stylera
base_fontname
is the font name as it appears in the printers font listings without the
first letter, up to (but not including) the font size.
font_style
can be one of the letters
R,
I,
or
B,
indicating the font styles Roman, Italic and Bold respectively.
For instance, if the printer's
font listing A
shows font `Nelite12I.ISO_USA', the corresponding entry in the font
description file is
lbpname NeliteI
Note that you may need to modify
grolbp
to add support for new bitmapped fonts, since the available font names and
font sizes of bitmapped fonts (as documented above) are hard-coded into the
program.
*
For scalable fonts,
printer_font_name
is identical to the font name as it appears in the printer's
font listing A.
For instance, to select the `Swiss' font in bold style, which appears in
the printer's
font listing A
as `Swiss-Bold', the required
lbpname
command line is
