       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

       \DR 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).


       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’.

              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.

              Print the version number.

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

       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    |              |


       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(1) how to set the paper dimensions in the DESC file.

       To set the paper size in the command line, add

         -p 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.


       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.


       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

       ·      For bitmapped fonts, printer_font_name has the form

                N〈base_fontname〉〈font_stylebase_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

              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

       ·      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.
