Description         top

       This GNU roff output driver translates the output of troff(1)
       into a CaPSL and VDM format suitable for Canon LBP-4 and LBP-8
       printers.  Normally, grolbp is invoked by groff(1) when the
       latter is given the “-T lbp” option.  (In this installation, ps
       is the default output device.)  Use groff's -P option to pass any
       options shown above to grolbp.  If no file arguments are given,
       or if file is “-”, grolbp reads the standard input stream.  It
       writes to the standard output stream.

       The driver supports the Dutch, Swiss, and Swiss-Narrow scalable
       typefaces, each in the regular, bold, italic, and bold-italic
       styles.  Additionally, the bitmapped, monospaced Courier and
       Elite typefaces are available in regular, bold, and italic
       styles; Courier at 8 and 12 points, Elite at 8 and 10 points.
       The following chart summarizes the groff font names used to
       access them.

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

   Paper format, orientation, and device description file
       grolbp supports paper formats “A4”, “letter”, “legal”, and
       “executive”.  These are matched case-insensitively.  The -p,
       --papersize option overrides any setting in the device
       description file DESC.  If neither specifies a paper format, A4
       is assumed.

       In its DESC file, grolbp (case-insensitively) recognizes an
       orientation directive accepting one mandatory argument, portrait
       or landscape.  The first valid orientation directive encountered
       controls.  The -l, -o, and --orientation command-line options
       override any setting in DESC.  If none of the foregoing specify
       the orientation, portrait is assumed.

   Font description files
       In addition to the font description file directives documented in
       groff_font(5), grolbp recognizes lbpname, which maps the groff
       font name to the font name used internally by the printer.  Its
       syntax is as follows.
              lbpname printer-font-name
       lbpname's argument is case-sensitive.  The printer's font names
       are encoded as follows.

       For bitmapped fonts, printer-font_name has the form Nbase-font-
       name⟩⟨font-style⟩.  base-font-name is the font name as it appears
       in the printer's 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 roman, italic, and bold
       styles, respectively.  For instance, if the printer's “font
       listing A” shows “Nelite12I.ISO_USA”, the corresponding entry in
       the groff font description file is “lbpname NeliteI”.  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-italic style, which
       appears in the font listing as “Swiss-BoldOblique”, “lbpname
       Swiss-BoldOblique” is the required directive, and this is what we
       find in the groff font description file HBI for the lbp device.

   Drawing commands
       For compatibility with grolj4(1), an additional drawing command
       is available.

       \D'R dh dv'
              Draw a rule (solid black rectangle) with one corner at the
              drawing position, and the diagonally opposite corner at
              the drawing position +(dh,dv).

Options         top

       -h and --help display a usage message, while -v and --version
       show version information; all exit afterward.

       -c num-copies
              Produce num-copies copies of each page.

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

              Format the document in landscape orientation.

       -o orientation
              Format the document in the given orientation, which must
              be “portrait” or “landscape”.

       -p paper-format
              Set the paper format to paper-format, which must be a
              valid paper format as described above.

       -w width
              Set the default line thickness to width thousandths of an
              em; the default is 40 (0.04 em).

Environment         top

              device's directory of device and font description files.
