History of Western typography Johannes Gutenberg employed the scribe Peter Schöffer to help design and cut the letterpunches for the first typeface—the D-K type of 202 characters used to print the first printed books in Europe. A second typeface of about 300 characters designed for the 42-line Bible c. 1455 was probably cut by the goldsmith Hans Dunne with the help of two others—Götz von Shlettstadt and Hans von Speyer.
