I used a dithering algorithm (https://en.wikipedia.org/wiki/Dither) to generate a multicolor svg file from a png (I think I did it using Processing).

Then, the sender software allows you to change tools between colors, so I used multiples pens. It's pretty straightforward as long as the machine does not lose steps between passes.
