Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by the printing press. Then, the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating printed products identical to the printing plate.

The pushers 708 that are staggered and move back and forth push the side of the paper adsorbed on the conveyor belt 2, and continuously adjust the direction of the paper, which greatly ensures that it can accurately enter and pass through the printing machine during the printing process.
