Around this time, the printing press was in operation, and a German poem had been printed, possibly the first item to be printed there. By this date, Gutenberg may have been familiar with intaglio printing; it is claimed that he had worked on copper engravings with an artist known as the Master of Playing Cards. This was a milestone for Gutenberg's movable-type printing technology as his printing press became operational and the new technology started to take shape.
