Vinyl cutter plot/print Driver?

Not sure where to ask this.

I just got one of these cheap vinyl cutters.(see link below) I'd like to
know if anyone has a suggestion on how to get AutoCad to recognize it
and maybe plot to it. The unit can run a pen.

Right now the process that works is to open the DWG in Corel X3, then
export to Illustrator .AI format and then open the file in the included
Signcut X2 software and plot.

I'm hoping there is a simpler way. Any suggestions on a driver that
would make the cutter visible to Autocad. I'd like to not have to go
through Signcut.

The cutter/plotter is on the serial port com02, and it says DMPL HPGL
Compatible.

If I'm asking this in the wrong forum please feel free to suggest the
right one.
