This post has little to do with printers, but rather with printing technology. Below there’s a video of a waterfall that is controlled by a computer to “printing out” astonishing patterns and pictures. This waterfall is located in Canal City Hakata, a shopping and entertainment complex in Fukuoka, Japan.
As you can see from the video, the waterfall seems to function using same techniques as an inkjet printer. Basically a computer is controlling hundreds of nozzles to precisely deliver water drops so that they fall forming images or texts.
