grolj4 - groff driver for HP Laserjet 4 family


grolj4 [ -lv ] [ -d [n] ] [ -c n ] [ -p paper_size ] [ -w n ] [ -F dir ] [ files... ]

It is possible to have whitespace between a command line option and its parameter.


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.


Print n copies of each page.
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.
Set the paper size to size, which must be one of letter, legal, executive, a4, com10, monarch, c5, b5, dl.
Print the version number.
Set the default line thickness to n thousandths of an em. If this option isn't specified, the line thickness defaults to 0.04~em.
