[0054] see figure 1 , an embodiment of the present invention provides a printing device, including:
[0055] The printing transmission mechanism 20a is used to convey the printing medium 60a including the radio frequency identification label, and the printing medium includes several sections of printing areas;
[0056] A printing unit 70a, configured to print on the printing surface of the printing medium 60a in the target printing area;
[0057] The radio frequency tag reading and writing execution unit 50a is arranged on the side of the printing unit 70a close to the printing surface, and is used to read and write the radio frequency identification tag in the printing medium;
[0058] The printing transmission mechanism is also used for sending the printing medium in the target printing area away from the printing unit if the printing and reading and writing of the radio frequency identification label are completed. Optionally, the radio frequency identification label is provided with an RFID chip, and the printing medium can be thermal printing paper, etc., and relevant characters, symbols, patterns, two-dimensional codes, etc. can be printed on the surface of the printing medium through the printing unit.

[0060] Optionally, the print information may be obtained through human-computer interaction devices such as keyboards and touch screens. The printing information can also be obtained through the information receiving device provided by the printing device to obtain relevant printing information transmitted over the network, such as transmitting the printing information to the printing device through WiFi, Bluetooth, 5G network, etc. The printing information can also be obtained by reading the information stored in the computer-readable storage medium by the printing device, for example, by reading the information in the USB flash drive connected through communication as the printing information and the like.

[0062] Optionally, the completion of printing can be judged by relevant technical means in the field, which is not limited here.
[0063] Optionally, the completion of reading and writing of the radio frequency identification tag can also be judged by related technical means in the field, which is not limited here.
[0064] Optionally, radio frequency identification tags are included in each printing area.
[0065] Sometimes, the RFID tag is not completely covered in the printing area, because the printing unit may require a certain displacement of the printing medium to complete the printing when performing the printing operation. At this time, the RFID tag reading and writing execution unit can The positional relationship between the tag and the radio frequency tag reading and writing execution unit is determined to determine the best reading and writing position, and the radio frequency identification tag is read and written.
[0066] Optional, continue to see figure 1 , the radio frequency tag reading and writing execution unit is arranged on the print head side of the printing unit, which can realize that the radio frequency tag reading and writing execution unit reads and writes the radio frequency identification tag in the printing medium when the printing unit is close to the printing surface for printing, thus The two dimensions of printing on the printing surface and reading and writing of radio frequency identification tags can be realized based on the fact that the printing medium is at the same position.
[0067] Optionally, if the printing on the printing surface is completed and the reading and writing of the radio frequency identification tag is also completed, the printing transmission mechanism is also used to transport the printing medium that has been printed on the printing surface and the reading and writing of the RFID tag away from the printing unit.

[0070] Optionally, since the radio frequency tag reading and writing execution unit is arranged on the side of the printing unit close to the printing surface, the distance between the side of the printing unit near the printing surface and the printing surface can be approximately understood as the distance between the radio frequency tag reading and writing execution unit and the radio frequency identification tag Therefore, based on the relationship between the reading and writing distance and the preset reading and writing distance range, the radio frequency tag reading and writing execution unit can be controlled to read and write the radio frequency identification tag in the printing medium.
[0071] Optionally, when the printing unit prints on the printing surface, the distance between the printing unit and the printing surface tends to be shortened (it may be that the printing unit falls to the printing surface, or the printing medium is lifted toward the printing unit, etc.), In the printing process, the radio frequency tag reading and writing execution unit is controlled to read and write the radio frequency identification tag in the printing medium, and the reading and writing distance can also be controlled to be within the preset reading and writing distance range before or after printing, so as to control the radio frequency The tag reading and writing execution unit reads and writes the radio frequency identification tags in the printing medium.

When the RFID tag in the printing medium is located under the RFID tag reading and writing execution unit, the distance between the RFID tag reading and writing execution unit and the RFID tag is very close during the printing process, which is much smaller than the working wavelength of the RFID tag. Therefore, on the one hand, the RFID tag The read-write execution unit can transmit information with the radio frequency identification tag through the induction field. Information transfer is carried out with RFID tags in other nearby printing media, so it is guaranteed that there will be no problems of over-reading, misreading or failing to read RFID tags.
