grolbp - groff driver for Canon CAPSL printers (LBP-4 and LBP-8 series laser printers).  


grolpb [ -l ] [ --landscape ] [ -v ] [ --version ] [ -c n ] [ --copies= numcopies ] [ -p paper_size ] [ --papersize= paper_size ] [ -o orientation ] [ --orientation= orientation ] [ -w width ] [ --linewidth= width ] [ -F dir ] [ --fontdir= dir ] [ -h ] [ --help ] [ files... ]


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 `landscape'.

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.

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
Swiss Narrow



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



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 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

lbpname Swiss-Bold

The argument of lbpname is case sensitive.
