I've been programming some CAD algorithms during the last two months and found myself buying cheap pens for a cheap plotter (a Silhouette machine), to make geometric diagrams. Can't say that the process is more efficient than a color printer[^1], but it is way cheaper than those damn color toners and the profit-maximizing ways the printer accounts for its consumption. And the pen strokes on paper look cool, and one can chose different pens to draw different layers in the diagrams.

[^1]: Though, in truth, the plotter is extremely reliable and fast. Inkjet printers on the other hand have a lengthy warmup and drivers are finicky to the point one imagines they constantly are on the lookout for new ways to botch a job.
