A nice trick: how to make Brother printers print files of HP-GL plotter commands. It may work with any PCL printer though.

@MMagdowski Der Vollständigkeit halber: Das war eine digitale Abgabe als Bild?
Bei genauer Betrachtung der Abgabe und der Gemini-Resultate: die Schrift ist zu regelmäßig, die Spiralen im Spiralblock zu sauber, die Reflektionen zu gleichmäßig und unplausibel. Mit dem Angriff #Raytracing (und ein paar ordentlichen ranz-Filtern fürs #Postprocessing) wird das alles in Ordnung kommen!!11😂
Kommen wir also wieder zurück zu in-person mündlichen Prüfungen mit dummen Fragen? Für remote calls scheint's ja schon epic Interview-Hilfen mit live Transkription, Speech-Suggestion-Overlay und Auto-Whiteboarding zu geben...
Oder es werden schöne gammlige Spiralblockblätter mit Kugelschreiberspuren, Rand usw gefordert. Dann müssen die Studis das LLM wenigstens noch zur Produktion von akzeptablen #HPGL für den Zweck bringen und kompetent mit einem #Stiftplotter umgehen...Gibts die Teile überhaupt noch?

That Brother laser printer you bought can also pretend it's a plotter

HP 9872C plots HPGL graphics from James Webb Space Telescope
On YouTube you can find a video showing how the picture was created.

Another plot from a NASA graphic. It's a Casini Spacecraft. I uploaded the full plot to YouTube.

I was gonna write some code on my #Swift #HPGL #GenerativeArt project, but I can’t decide which way to go with it and I lost all momentum in my brain.
Back to playing #NoMansSky
[Terje Io] decided to breathe new life into an old pen plotter -- the CX6000 from C. Itoh, a Japanese company that made several printers for Apple in the 1980s. He keeps most of the framework, but the electronics get a major overhaul. The old motors are replaced, the controller and motor drivers are modernized using a Raspberry Pi Pico and stepper motor drivers. After tending to other auxiliary electronics like the control panel and limit switches, it's time to deal with the firmware.
Rather than reinvent the wheel, [Terje] sensibly built upon existing projects and refactored them for his application. G-Code processing is done by grblHAL, with an added mode to handle HPGL code. He modified the firmware from Motöri the Plotter project to parse HPGL, making his new CX6000+ bilingual.
We covered Motöri way back in 2009, and more recently we wrote about the Teensy Controller using grblHAL, one of the 32-bit big brothers of GRBL. Have you ever restored one of these old plotters? Or is it easier to just build your own these days?
