William Bullock (1813 – April 12, 1867) was an American inventor whose 1863 improvements to Richard March Hoe's rotary printing press helped revolutionize the printing industry due to its great speed and efficiency.

The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern ...

Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners , laser printers , and photocopiers , but for many years they were the primary means of reproducing documents for limited-run distribution.
During the 1980s, a convergence began in some high-end machines towards what came to be called a multi-function printer: a device that combined the roles of a photocopier, a fax machine, a scanner, and a computer network-connected printer. Low-end machines that can copy and print in color have increasingly dominated the home-office market as ...
