Print What?

Here's something I encountered a few days ago which made me happy and sad at the same time.

I was reading Cory Doctorow's new book, Enshittification (yes, he made up the word, and yes, it's now part of the modern vocabulary, I think ). I will probably go into a full review of the book once I'm finished with it. In a short part of the book Doctorow writes about the enshittification of HP inkjet printers; no surprise there - HP wants to force you to buy their ink, for like 30 times more than other companies' ink products. Anyway, one of the things inkjet printers can do now, with the right kind of ink, is print electrically conductive circuits! That is so cool, from a geek point of view!
