HP plotters

No question about it... the HPGL allows you to vary the pen acceleration,
force, and speed, but the mechanism is one designed for pens and not for
much side-load. The force needed to lift the pen is pretty minimal, BTW.
Now, most of my experience is with the 7585B, which is a DRUM plotter, but
I've used the 7550. Those much slower 72xx series models are robust enough
to use for light work, but their pen mechanism, IIRC, is even less robust
that that on the high-speed models.
