       laser printers).

DESCRIPTION
       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
       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.

       -cnumcopies
       --copies=numcopies
              Print numcopies copies of each page.

       -l
       --landscape
              Print the document with a landscape orientation.

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

       -oorientation
       --orientation=orientation
              Print the document with orientation orientation, which must be
              `portrait' or `landscape'.

       -wwidth
       --linewidth=width
              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.

       -v
       --version
              Print the version number.

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

       -h
       --help Print a short help text.

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:

          +----------------+-----------+--------+----------+--------------+
          |   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    |              |
          +----------------+-----------+--------+----------+--------------+
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(5) 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:

         lbpname printer_font_name

       o      For bitmapped fonts, printer_font_name has the form

                N<base_fontname><font_style>

              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.

       o      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.
