Johannes Gutenberg invented the printing press during the 15th century, which revolutionized the production and dissemination of books, making them quick and cheap to mass produce.

Samuel Adams showed Ratonhnhaké:ton how to lower his notoriety by bribing printers to cease producing wanted posters, or to print his own propaganda. On one occasion, Ratonhnhaké:ton simply beat up a printer distributing pamphlets slandering his friend Dr. Lyle White.
