Legal analysis: invalid. Generally speaking, a contract takes effect after being signed or sealed by all parties. If one party only prints his name without autograph or finger printing, and the contract is not recognized by other forms, it shall be deemed that the contract is not established. If the name of the party is printed on the contract, and the party does not sign it, but presses the handprint, the contract is established. If the contract does not violate the validity provisions of laws and regulations, it will take effect.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
