DEVELOPMENTS IN PRESS TECHNOLOGY
A printing press is a device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. Printing Press was first invented by the German Johanes Guttenberg around 1440. Johanes Guttenberg had employed wooden presses using similar mechanical principles as those of the agricultural machinery. The way it worked was to place the medium ( such as paper ) face down upon the type, after which a screw was tightened to make the impression. While this method has been refined for the past three centuries, the basic principles remained unchanged.

The next press technologies developed was the iron hand-press, introduced to the UK by Lord Stanhope early 19th century, followed by the Colombian presses in the US, and the Albion presses in the UK. These presses differ from the wooden presses in a way that they used lever mechanism that allowed them to generate more power of impression in a single movement and better precision. The industrialisation of printing process continued with the development of cylinder press, invented in London by German designers Koenig and Bauer. Cylinder presses carried the paper over the type on a rolling cylinder, a principle that led to mechanisation. While mechanisation quickly spreaded throughout most of the newspaper industry, book-publishing houses still continued to use the hand-presses throughout the 19th century.
Printing press allow people to speed up their work and be consistent compared to writing with hand.
