Risograph

Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, that are designed mainly for high-volume photocopying and printing. It was released in Japan in August 1986. It is sometimes called a digital duplicator or printer-duplicator, as newer models can be used as a network printer as well as a stand-alone duplicator. When printing or copying many duplicates of the same content, it is typically far less expensive per page than a conventional photocopier, laser printer, or inkjet printer.
