A long time ago, there was a machine called a "mimeograph duplicator"; it worked by copying a typed stencil onto sheets of paper, by means of a rotating drum -much like a printing press.
For many years they were used everywhere, and even tests in some schools were printed using these machines -in a peculiar purple ink. But photocopiers quickly took the market over in the 1970's, and they are now just a memory.
