Chinese Chemists Create Printer that Uses Water Instead of Ink

A team of chemists claims their "water-jet" technology allows each page to be reprinted dozens of times—a money- and tree-saving option in a digital world that still relies heavily on hard copy.

"Several international statistics indicate that about 40 percent of office prints (are) taken to the waste paper basket after a single reading," said Sean Xiao-An Zhang, a chemistry professor at Jilin University in China, who oversaw work on the innovation.
