EAGLE will output various forms of HPGL via its CAM processor.
You may have to spend some time making sure that its idea of your "pen =20
width" matches your plotter.

Most of the milling-based PCB makers (LPKF, TTech) apparently use =20
HPGL, so the utilities that come with them will input gerber and =20
output hpgl (at least, this is true of LPKF CircuitCam 3.x)  I would =20
expect this to be true of a bunch of the hobbyist (open source) =20
milling software as well.
