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