I know it can feel like that, car3less, but have you tried some of the Watson recipes? For a supercomputer with no authentic tastebuds, it knows how to make an awesome cherry cobbler.

On the other hand, Watson can do the things it can do because it has a wide palette of spices and ingredients to work with in a chef's kitchen (or in my case, shopping list). A printer by necessity would have a limited, perhaps highly limited palette of flavors to choose from, and there's not a simple set of flavor molecules you can mix like there are colors with a color printer.

By the time you have a printer that could actually make a whole menu of items, you'd also have to worry about maintaining dozens of different build materials. Just look at the Coca-cola Freestyle machines when someone is replacing a cartridge, it's insane in there, and that only makes sweet drinks.
