HPGL to Arduino?

Hello, just wondering if there is a way to use HPGL on the Arduino.

I'm working on a Plotter here http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1248670046 (based on the Drawbot http://www.as220.org/labs/drawbot/instructions.html)

And thought HPGL my be my solution for stight line plotting, using a solenoid to lift the pen?
