When did Mimeographs stop being used?

Risographs and copiers look extremely similar from the outside. They even print single-color pages that look the same. However, photocopiers and Risographs work differently. Risographs are based on a stencil-and-ink system, while photocopiers use electrostatically charged toner particles, like a laser printer.
How much does a RISO cost?
