The art of printing goes back to around A. D. 175, where it was employed by the Chinese, who cut impressions into blocks of wood, applied ink, laid paper over the block and pressed the two together, leaving the inked impression on the paper. This crude method of printing took root in other parts of the world, but didn't change much until the 1100s.
Another device, called an electrostencil machine, sometimes was used to make mimeo stencils from a typed or printed original. It worked by scanning the original on a rotating drum with a moving optical head and burning through the blank stencil with an electric spark in the places where the optical head detected ink.

The company was founded in 1883 [1] in Chicago as a lumber company by Albert Blake Dick (1856 – 1934). It soon expanded into office supplies and, after licensing key autographic printing patents from Thomas Edison, became the world's largest manufacturer of mimeograph equipment (Albert Dick coined the word "mimeograph").
