NAME
grolj4 - groff driver for HP Laserjet 4 family
SYNOPSIS
grolj4 [ -lv ] [ -d[n] ] [ -cn ] [ -ppaper_size ] [ -wn ] [ -Fdir ] [ files... ]
DESCRIPTION
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.
OPTIONS
It is possible to have whitespace between a command line option and its parameter.
