* Use a 3D printer for plotting: (thanks @jeevank for sharing this) https://medium.com/@urish/how-to-turn-your-3d-printer-into-a-plotter-in-one-hour-d6fe14559f1a - Use a 3D printer for plotting: (thanks @jeevank for sharing this) https://medium.com/@urish/how-to-turn-your-3d-printer-into-a-plotter-in-one-hour-d6fe14559f1a
* Convert a PDF to GCode: follow [this guide using Inkscape to convert a PDF to an SVG](https://en.wikipedia.org/wiki/Wikipedia:Graphics_Lab/Resources/PDF_conversion_to_SVG#Conversion_with_Inkscape), then use it with svg2gcode - Convert a PDF to GCode: follow [this guide using Inkscape to convert a PDF to an SVG](https://en.wikipedia.org/wiki/Wikipedia:Graphics_Lab/Resources/PDF_conversion_to_SVG#Conversion_with_Inkscape), then use it with svg2gcode
* Are shapes, fill patterns supported? All objects can be converted to paths in Inkscape with `Object to Path` for use with this program. Not sure how practical fill patterns would be -- if you have ideas, feel free to open as issue or a PR. - Are shapes, fill patterns supported?

* What about a generic PPD driver for using a plotter as a printer? I thought about doing something like this where you package ghostscript + inkscape + svg2gcode but that would take a lot of time - What about a generic PPD driver for using a plotter as a printer?
