This paper proposed a quantum group signature based on printer management model.Using quantum entanglement,the member of printer group Alice may sign the message on behalf of her group,and the printer manager Bob can confirm that the signature from the group,however he can not sure which member did it.If there is dispute,the group manager Trent will trace the illegal printing.Compared with existing classical signature schemes and quantum signature schemes,the quantum group signature has not only the group property,but also the unconditional security,which can be widely used in electronic voting and e-commerce.
