What office machine did Leonardo da Vinci design to make many copies of written text?

Leonardo da Vinci designed a printing press concept for producing multiple copies of written text.

The design appears among his studies of mechanical devices and reflects the influence of movable-type printing, which had spread through Europe after Johannes Gutenberg’s work in the mid-fifteenth century. Leonardo’s version explored ways to improve the regular movement of paper and the pressure applied during printing.

Leonardo did not invent the printing press. Gutenberg’s printing system was already operating decades before Leonardo’s mature engineering notebooks. Leonardo’s importance here is as a designer who examined the machine’s mechanics and proposed refinements, not as the originator of European printing.

The distinction matters because Leonardo’s notebooks contain both original inventions and studies of existing technologies. His printing-related drawings show the Renaissance habit of analysing machines through diagrams, measurements, and mechanisms. They also illustrate how quickly printing became an object of technical experimentation after its introduction to Europe.
