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'
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'.
Print the version number.
Prepend directory dir/devlbp to the search path for font and device description files.
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 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).
To set the paper size in the DESC file, insert in that file a line containing papersize desired_papersize, where desired_papersize is:
One of the recognized paper sizes: `a4', `letter', `legal' or `executive'.
A custom defined paper size, as described in the CUSTOM PAPER SIZES subsection below.
The name of a file (e.g. /etc/papersize) whose first line must be the desired paper size in one of the above formats.
If there are various papersize lines in the DESC file, only the first valid one is used.
To set the paper size in the command line, add
to the other grolbp options, where desired_papersize is in the same format as in the DESC file.
Paper sizes are case insensitive (i.e., `A4' is the same as `a4').
Custom defined paper sizes are in the form custlengthxwidth where length and width are the dimensions of the paper you want to to use, specified in printer units (1/300 of an inch). For instance, to print in a postcard sized paper which is two inches long and four inches wide you can insert a line containing
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:
As with paper sizes, only the first valid orientation command in the DESC file is used.
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 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
Device description file.
Font description file for font F.
