From Wine Press to Printing Press
Gutenberg adapted the structure of the wine press already mature in Europe to provide the even pressure printing required, and at the same time developed a process for casting movable type from a lead-tin-antimony alloy; this trinity system of "type + ink + press mechanism" was the basic paradigm of European printing technology for the nearly four hundred years after, until replaced by the industrial press in the nineteenth century.
The Inventor Lost His Own Workshop
To raise the startup capital for his printing business, Gutenberg borrowed a huge sum from the Mainz merchant Johann Fust, and in 1455, unable to repay on time, was sued by Fust, who won and directly took over Gutenberg’s printing equipment and workshop, then went on in partnership with Gutenberg’s assistant to continue the printing business — this story of "the inventor created printing, yet gained nothing in patent and commercial operation" is a classic case in the history of technology of the separation of "invention" and "profit."
