Generally, a typed menu does not need to be stamped, because it has the legal evidential effect. According to relevant laws and regulations, the typed menu is recognized as a legal and valid transaction voucher, which has the same legal effect as the handwritten menu. Machine-made menu usually includes the name of the merchant, the name of the dish, the price, the quantity and other information, which is recognized and confirmed by the merchant.

There are several main reasons why the machine-printed menu does not need to be stamped:

1. With the development of electronic equipment, the machine-printed menu has anti-counterfeiting function, which can effectively prevent tampering and forgery, so there is no need for additional stamping to increase its credibility.

2. The printing process of the machine-printed menu has already taken some regulatory measures, including the records of the printer and the bills of the merchants, which can provide evidence to prove the authenticity of the menu.

3. At present, electronic invoices and electronic certificate have been used in many places. As a kind of electronic certificate, machine-made menu has been recognized by law and widely used.

It should be noted that although the machine-printed menu does not need to be stamped, merchants should ensure its authenticity and accuracy when using the machine-printed menu, and at the same time abide by relevant laws and regulations. In addition, under certain circumstances, such as involving important contracts or legal disputes, additional supporting materials may be needed to support the effectiveness of the machine-made menu. Therefore, under specific circumstances, merchants can choose whether to use seals or not to increase the credibility of evidence.
