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'R dh dv'

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.

-c num-copies

Print num-copies copies of each page.


Print the document with a landscape orientation.


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

-p paper-size

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


Print the version number.

-w line-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.

-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 lj4.

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

pclweight N

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

pclstyle N

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

pclproportional N

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