grolbp - groff output driver for Canon CaPSL printers
grolbp [-l] [-c num-copies] [-F font-directory] [-o orientation]

grolbp --version
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.
Typefaces
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.

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 N⟨base-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).
-h and --help display a usage message, while -v and --version
show version information; all exit afterward.
-c num-copies
--copies=num-copies
Produce num-copies copies of each page.
-F font-directory
--fontdir=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.
-l
--landscape
Format the document in landscape orientation.
-o orientation
--orientation=orientation
Format the document in the given orientation, which must
be “portrait” or “landscape”.
-p paper-format
--papersize=paper-format
Set the paper format to paper-format, which must be a
valid paper format as described above.
-w width
--linewidth=width
Set the default line thickness to width thousandths of an
em; the default is 40 (0.04 em).
GROFF_FONT_PATH
lists directories in which to seek the selected output
device's directory of device and font description files.
See troff(1) and groff_font(5).
/usr/local/share/groff/1.23.0/font/devlbp/DESC
describes the lbp output device.
/usr/local/share/groff/1.23.0/font/devlbp/F
describes the font known as F on device lbp.
/usr/local/share/groff/1.23.0/tmac/lbp.tmac
defines macros for use with the lbp output device. It is
automatically loaded by troffrc when the lbp output device
is selected.
