Looks like it’s basically an inkjet printer with edible ink.

Laser engravers aren’t that much simpler than 2D printers, and 3D printers have very much fallen in price over recent years.
I think you’re overstating the complexity of printers greatly, either that or you’ve literally never heard of 3D printing or a pastry printer. Non-ink-based printers have been getting cheaper and cheaper, in addition to becoming more abundant and with more options (different plastics, metal printing, food printers, embroidery machines, etc.)
I watched my husband build a 3D plastic printer, they are not complicated to the level of black magic, and are well below what a regular consumer can afford.
Back to food printers, though, Amazon actually has a ton of them. It turns out Latte printers do print in food coloring, and they also have things like a pancake printer, and a fancy chocolate printer that prints 3D shapes made out of chocolate.
