Legal analysis: invalid, it must be signed by the contract signer himself, not printed. Because the premise of signing a contract must be the true intention of the parties to the contract, only by signing it in person can we judge whether it is the true intention of the parties to the contract in case of dispute. If it is a printed signature, it is impossible to directly judge whether it is the true intention of the parties to the contract, which does not meet the basic requirements for the establishment of the contract. Moreover, according to the law, a contract signed in written form is established when the parties sign or seal it. Excluding the printed signature, the contract is established. Therefore, when signing a contract, you can't print the signature directly with a machine, but you need to sign it by hand, otherwise it will affect the establishment and effectiveness of the contract.
