"Seal name" generally appears at the signature of a contract (agreement), and is sometimes written as "seal name". In the contract (agreement), "printing name" means "printing signature", that is, the signer's name can be typed by computer, which can be artistically decorated, but it should not affect its recognition, and finally form an electronic version of the contract (agreement) or print it as a written text. Such "printing" and "writing" are different in appearance.
