printing machine is a machine for printing words and images.

Modern printing machines are generally composed of plate loading, inking, stamping and paper feeding (including folding). Its principle is that the characters or images to be printed are first made into printing plates, which are installed on the printing machine, and then the ink is coated on the places with characters and images on the printing plates manually or by the printing machine, and then directly or indirectly transferred to paper or other substrates (such as textiles and metal plates).
