.SH Description
.\" ====================================================================
.
This GNU
.I roff
output driver translates the output of
.MR \%troff 1
into a CaPSL and VDM format suitable for Canon LBP-4 and LBP-8 printers.
.
Normally,
.I grolbp
is invoked by
.MR groff 1
when the latter is given the
.RB \[lq] \-T\~lbp \[rq]
option.
.
(In this installation,
.B \%ps
is the default output device.)
.
Use
.IR groff 's
.B \-P
option to pass any options shown above to
.IR grolbp .
.
If no
.I file
arguments are given,
or if
.I file
is \[lq]\-\[rq],
.I grolbp
reads the standard input stream.
.
Output is written to the standard output stream.
.
.
.\" ====================================================================
.SS 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
.I groff
font names used to access them.

.SS "Paper format, orientation, and device description file"
.\" ====================================================================
.
.I grolbp
supports paper formats
.RB \[lq] A4 \[rq],
.RB \[lq] letter \[rq],
.RB \[lq] legal \[rq],
and
.RB \[lq] executive \[rq].
.
These are matched case-insensitively.
.
The
.BR \-p ,
.B \-\-papersize
option overrides any setting in the device description file
.IR DESC .
.
If neither specifies a paper format,
A4 is assumed.
.
.
.P
In its
.I DESC
file,
.I grolbp
(case-insensitively) recognizes an
.B orientation
directive accepting one mandatory argument,
.B portrait
or
.BR landscape .
.
The first valid orientation directive encountered controls.
.\" XXX: This is inconsistent with other description file processing.
.
The
.BR \-l ,
.BR \-o ,
and
.B \-\-orientation
command-line options
override any setting in
.IR DESC .
.
If none of the foregoing specify the orientation,
portrait is assumed.
.
.
.\" ====================================================================
.SS "Font description files"
.\" ====================================================================
.
In addition to the font description file directives documented in
.MR groff_font 5 ,
.I grolbp
recognizes
.BR lbpname ,
which maps the
.I groff
font name to the font name used internally by the printer.
.
Its syntax is as follows.
.RS
.EX
.RI lbpname\~ printer-font-name
.EE
.RE
.
.
.BR lbpname 's
argument is case-sensitive.
.
The printer's font names are encoded as follows.
.
.
.P
For bitmapped fonts,
.I printer-font_name
has the form
.RS
.EX
.RI N\[la] base-font-name \[ra]\[la] font-style \[ra]
.EE
.RE
.I 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.
.
.I font-style
can be one of the letters
.BR R ,
.BR I ,
or
.BR B ,
.\" The bold-italic style apparently was not supported for bitmap fonts.
indicating the roman,
italic,
and bold styles,
respectively.
.
For instance,
if the printer's \[lq]font listing A\[rq]
shows \[lq]Nelite12I.ISO_USA\[rq],
the corresponding entry in the
.I groff
font description file is
.RS
.EX
lbpname NeliteI
.EE
.RE
.
You may need to modify
.I 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.
.
.
.P
For scalable fonts,
.I printer-font-name
is identical to the font name as it appears in the printer's \[lq]font
listing A\[rq].
.
For instance,
to select the \[lq]Swiss\[rq] font in bold-italic style,
which appears in the font listing
as \%\[lq]Swiss\-BoldOblique\[rq],
.RS
.EX
lbpname Swiss\-BoldOblique
.EE
.RE
is the required directive,
and this is what we find in the
.I groff
font description file
.I HBI
for the
.B lbp
device.
.
.
.\" ====================================================================
.SS "Drawing commands"
.\" ====================================================================
.
For compatibility with
.MR grolj4 1 ,
an additional drawing command is available.
.
.
.TP
.BI \[rs]D\[aq]R\~ "dh dv" \[aq]

(solid black rectangle)
