The following chart summarizes the font names you can use to
access these fonts:
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
To set the paper size in the command line, add
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:
Only the first valid orientation command in the DESC file
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:
- 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
- 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
- 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
The argument of lbpname is case sensitive.
