printer (n.)

"person who prints books, etc.; one who understands and carries on the business of typographical printing," c. 1500, agent noun from print (v.). Earlier as "a signet or seal" (early 15c.). As a mechanical device that prints, presses, or stamps by impression, from 1859, originally in telegraphy. In the computer sense, from 1946. The Printer's bible (c. 1702) was so called from the erroneous substitution of printers for princes in Psalms cxix.161, which led to the memorable misreading:

Printers have persecuted me without a cause.
