Johannes Gutenberg, a German craftsman and inventor, made the Gutenberg press. This innovative printing press was made in the 1400s and remained the standard until the 20th century. Read on from inventors.about.com/od/gstartinventors/a/Gutenberg.htm.
Gutenberg invented the printing with single reuseable lead cast letters in 1440AD for Europe. However, prints using carved wood panels were produced in China since 770AD, followed by single letter (symbols) prints using clay letters in 1040AD. In Korea single letter prints using wood, copper, lead or brass letters were made since 1234AD.
