Print in Europe — The Gutenberg Press:
Before print, books were copied by hand, which was slow and expensive. Johann Gutenberg, drawing on his knowledge of wine/olive presses and metal-casting, developed the moveable type printing press by 1448. He adapted the olive press as the model and used metal moulds to cast letter types for the Roman alphabet.
This shift from hand-copying to mechanical printing led to the Print Revolution.

Examiners expect three clear points for 3 marks:
Avoid writing an essay. Name Gutenberg, mention moveable type, the Bible, and the spread across Europe. The book production statistics (20 million / 200 million) are a favourite examiner point.
