Copying machines are usually mechanically driven, so stamps cannot be printed directly. If you need to stamp the document, you can print it out first and then stamp it with a seal. However, sometimes we will encounter some special circumstances, such as printing and stamping several documents together. In this case, we can try some other methods.

Method 1: Use digital signature.

Digital signature is a kind of electronic seal, which can be generated by computer, so it can be directly stamped on the document. This method can ensure the integrity and authenticity of the document, and it is also recognized by law. However, before using digital signature, we need to apply for a key certificate and install the corresponding digital signature software in the computer system.

Method 2: Use a stamp scanner.

The seal scanner can digitize the image of the seal and save it in the computer. When we need to stamp, we can select the corresponding stamp image from the computer and print it on the document. This method requires us to equip with a seal scanner, and we need to scan all the seals that need to be used in advance.

Method 3: Use a printed board.

The printing board can convert seals into patterns and print them on documents. This method is more suitable for situations that need a lot of printing, such as contracts and official letters. The method of using the printing plate is to make the seal into a cliche, then insert the cliche into a specific printer, and finally put the document to be printed into the printer for printing.

In short, although the copier can't print the seal directly, we can achieve the purpose of stamping the document by other auxiliary means. Different methods have their own advantages and disadvantages, and they need to be selected according to the actual situation.
