A friend of mine had a plotter in which he substituted an Exacto type knife blade for the pen, and plotted into vinyl (with adhesive backing) which allowed for some amazing stuff.
He did some wild murals with it (varied colors).
I can recommend the Cricut Explore Air for this. The software is janky but the machine works great for cutting out vinyl, paper, etc. Also takes pens which means I can do my own generative plotting (once I buy some pens / an adaptor.)
