Letterpress printing was the normal form of printing text from its invention by Johannes Gutenberg in the mid-15th century to the 19th century and remained in wide use for books and other uses until the second half of the 20th century. Letterpress printing remained the primary means of printing and distributing information until the 20th century, when offset printing was developed, which largely supplanted its role in printing books and newspapers. All forms of data collection were affected by the invention of letterpress printing, as were many careers such as teachers, preachers, physicians, and surgeons and artist-engineers. More recently, letterpress printing has seen a revival in an artisanal form.
