Low tech? I'm into carbon-based self-replicating multicore solar nanotech autonomous food printers. My kid calls them apple trees.
As for the article, I'd be wary of the use of the terms printing. Automatic sowing and pre-packaged planning, maybe. They are not "printing" like a 3d printer or an organ printer.
Permaculturists do a similar thing when we do those nutrient balls for seeds. Now imagine instead of a ball it's a thick bedsheet/blanket of sorts, and you have seeds and nutrients embedded in a non-random layout to bootstrap a little guild. Maybe you get 3 sheets, one for year 1, another for year 2 etc to have a growth strategy over time. It'd be a tough thing to balance labor savings vs lack of context-based decisions and observation if you have the time to do it manually. But as a fast bootstrap seems like a useful idea.
