'Hewlett-Packard Graphics Language'
All commonly used features of HP-GL are currently supported apart from those that are only appropriate to a continuous-feed plotter. Some plotter drivers make unjustified assumptions about the default configuration which can cause problems. The default HP-GL palette is set to RGB when an IN (initialize) command is encountered, but prior to that only a black pen (1) and a white pen (0) are defined.
