groff driver for HP LaserJet 4 family


grolj4 -l -c num-copies [-d [n]] -F font-directory -p paper-size -w line-width [file . . . ] grolj4 --help grolj4 -v grolj4 --version


grolj4 is a driver for groff that produces output in PCL5 format suitable for an HP LaserJet 4 printer.

There is an additional drawing command available:

\D'Rdhdv' Draw a rule (solid black rectangle), with one corner at the current position, and the diagonally opposite corner at the current position +(dh,dv). Afterwards the current position will be at the opposite corner. This generates a PCL fill rectangle command, and so will work on printers that do not support HPGL/2 unlike the other \ D commands.


Whitespace is permitted between a command-line option and its argument.

-cnum-copies Print num-copies copies of each page.

-l Print the document with a landscape orientation.

-d [n] Use duplex mode n: 1 is long-side binding; 2 is short-side binding; default is 1.

-ppaper-size Set the paper size to paper-size, which must be one of letter, legal, executive, a4, com10, monarch, c5, b5, dl.

-v --version Print the version number.

-wline-width Set the default line thickness to line-width thousandths of an em. If this option isn't specified, the line thickness defaults to 0.04 em.

-Ffont-directory Prepend directory font-directory/devname to the search path for font and device description files; name is the name of the device, usually lj4.

The following four commands are available additionally in the font description files:

pclweightN The integer value N must be in the range -7 to +7; default is 0.

pclstyleN The integer value N must be in the range 0 to 32767; default is 0.

pclproportionalN A boolean flag which can be either 0 or 1; default is 0.

pcltypefaceN The integer value N must be in the range 0 to 65535; default is 0.


GROFF_FONT_PATH A list of directories in which to search for the devname directory in addition to the default ones. See troff(1) and groff_font(5) for more details.
