What Leonardo da Vinci invention was a rotating machine for printing text and images?

Leonardo da Vinci designed a printing press concept using a rotating mechanism for printing text and images.

His notebooks contain studies of printing technology, including arrangements intended to improve the pressure and repeatability of impressions. A press transfers ink from prepared type or an image block onto paper, and a controlled mechanical movement helps produce more consistent pages.

Leonardo’s designs appeared after Johannes Gutenberg’s mid-fifteenth-century improvements to movable-type printing. He therefore did not invent printing or the first European printing press. His work belongs to a later tradition of refining machines that could make printing faster and more reliable.

The surviving sketches are sometimes discussed alongside Leonardo’s broader interests in publishing and technical illustration. The important distinction is between a printing press mechanism and movable type, which refers to the reusable letters or symbols placed in the press.
