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).


Note that there can be whitespace between a one-letter option and its argument; on the
other hand, there must be whitespace and/or an equal sign (‘=’) between a long-name option
and its argument.

Print numcopies copies of each page.

Print the document with a landscape orientation.

Set the paper size to paper_size, which must be a valid paper size description as
indicated in the section PAPER SIZES.

Print the document with orientation orientation, which must be ‘portrait’ or

Set the default line thickness to width thousandths of an em. If this option isn't
specified, the line thickness defaults to 0.04 em.

Print the version number.

Prepend directory dir/devname to the search path for font and device description
files; name is the name of the device, usually lbp.

--help Print a short help text.


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:

│ Typeface │ Regular │ Bold │ Italic │ Bold-Italic │
Dutch │ TR │ TB │ TI │ TBI │
Swiss │ HR │ HB │ HI │ HBI │
Swiss Narrow │ HNR │ HNB │ HNI │ HNBI │
Courier │ CR │ CB │ CI │ │
Elite │ ER │ EB │ EI │ │


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(5) how to set the paper dimensions in the DESC file.

To set the paper size in the command line, add

-p 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.


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.


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:

lbpname printer_font_name

· For bitmapped fonts, printer_font_name has the form


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

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

lbpname Swiss-Bold

The argument of lbpname is case sensitive.


A list of directories in which to search for the devname directory in addition to
the default ones. See troff(1) and groff_font(5) for more details.
