I love plotter art and have dabbled a bit myself. The really fun part is how pen-on-paper is not completely reliable or a perfect line. You get a little texture if the pen skips. You can use watercolor pens that bleed. You can get crazy with something like Copic markers on Yupo paper so the whole thing stays wet and smears for minutes. It's part of the art.
This bit from the article made me laugh ruefully though: "it's as simple as buying some black paper and a white gel pen." You can get some beautiful effects with white ink on black paper but it is notoriously difficult to get looking good. White ink is tricky stuff. But that's part of the fun!

I always thought of plotters as legacy tech, but considering the variety of marking tools you can attach to the head, I'm wondering if I should get one.
Does anyone know of an inexpensive plotter you can buy or build?

I made one for roughly $100 USD from an Arduino, steel rods, some stepper motors, and some 3D printed parts.
Having an existing 3d printer is a bit “draw the rest of the owl” for this, but being able to extend and modify a device like a pen plotter is pretty nice.

You can also pick up used older printers (like the Ender 3) secondhand VERY cheap and convert them.

Cricuts (and similar cutters, and multi-mode tools like the Xtool M1 and Bambu Lab H2D) have pen attachments

Yes. But no geek should be getting a Cricut when the Silhouette machines exist and are not so locked down and cloud encumbered.
Is there actual plotter simulation software I could be using?

My dad worked for Control Data in the 1980s and talks about hiding designs in period characters on his schematics. Talks about how the plotters would get to the period, hang out for a while and then continue.

Printers using CMYK isn't strictly true, right? Aren't you able to choose the ink colors when getting prints professionally made?

I had a summer job working at a print software company and they had a large format printer with, if I remember correctly, 12 different ink colours. These weren't spot colours - though that's also an example of going outside CMYK - but meant the printer supported a very wide colour gamut and subtle colour grading.
Anyway, yes, professional printing can go beyond just CMYK in various ways.

I have a Canon Pixma Pro 100 and it uses 8 different inks. The “Pro” really means professional. When used with the correct paper, it produces the same high quality prints as any professional service.
Looking at the artwork on my wall, there’s two big things that set prints apart from an original artwork. 1. Computer software doesn’t capture the imperfection of a physical medium. 2. Printers can’t reproduce the texture of layered colors.

You're correct, there are some more sophisticated processes used by specialty printers such as CcMmYK (https://en.wikipedia.org/wiki/CcMmYK_color_model). Something like this will use more inks and less halftones, giving better results in some cases.
Or are you referring to other printing methods, say for example silk screening? There, you would definitely select a specific ink to use. It just depends on what your goals are.

Or they could be referring to Spot Color.

One of my favorites is spot gloss.

At work we have CMYKW printers, which add an extra channel of white ink to the mix.

Yes, giclee printers typically have ten or more inks, and Risograph printers offer a wider but limited set of options.

Im on my second Bantam tools next draw and love it. Having made a similar transition from generative art to printmaking with a risograph and drawing with a pen plotter; I love the slow physical process of using them.

As a plotter artist also, I'm super happy to see this article on HN.

After rewatching that, I did a one-shot remake in p5js: https://g.co/gemini/share/b983a93e3ae2
