This is probably a nontrivial task, at least once you have filled areas,
shadows, many colors etc, due to the sreen beeing a raster device versus
the plotter being a vector oriented device. It's much easier once you used
only the handfull colors available on the plotter (thus avoiding the problem
to automatically map colors and/or generating seperation lines between two
different original colors mapping into the same plotter color) and retained
from using odd shapes, that couldn't easily be represented by arc's or poly-
gons available at HPGL. Take a closer look to the Reference Manual of your
printer and start replacing moves by PU and draws by PD instructions.
Alternatively you could try to find / write a BGI-driver for that plotter,
that sends appropriate instructions to the plotter.
