Plottergeist

Plottergeist understands HPGL and HPGL/2, and has built-in support for emulation of HP 7440, HP 7470, HP 7475, HP 7550 and HP 7570 pen-plotters.

The common ANSI and ISO paper sizes are selected from a list (A..D, A4..A0, and custom size), and the useable plot area is reported to the controlling instrument when requested.

All the page settings can be modified from a control panel, so that a graphic of arbitrary aspect ratio can be correctly displayed.
