That's interesting as a programming exercise, but HP's plotters all had a built-in language called HP-GL. And there's a GPL'ed tool that will emit HP-GL. I just can't recall what it's called. Seems like it was built in to some normal printing tool. HP Laserjet printers also supported HP-GL, so that was a nice way to get your plots without having to buy a more expensive dedicated plotter.
> That's interesting as a programming exercise, but
why is this a "but"? does the existence of HPGL negate the work being presented here somehow? modern plotters seem to have less capable control languages such as whatever the axidraw does, or G-code for most of the open source controllers. I guess folks assume you'll just be programmatically generating or converting to the output format anyways.
inkscape can output HPGL directly. there's also chiplotle which is a python library. i've tried to gather up all the other HPGL-related software i could find here: https://github.com/beardicus/awesome-plotters#hpgl
