Print program safety burning recording method, chip and printing consumable

Abstract

The invention provides a print program safety burning recording method, a chip and a printing consumable. The print program safety burning recording method includes the steps of acquiring the model number of a printer to be used through a terminal device, and sending the acquired printer model number to a cloud server; seeking corresponding print program ciphertext through the cloud server according to the received printer model number, and returning the print program ciphertext to the terminal device; sending the model number of the printer to be used to a secret key server through the terminal device; seeking a corresponding secret key factor through the secrete key server according to the received printer model number, and returning the secret key factor to the terminal device; performing calculation through the terminal device according to the secret key factor so as to acquire a corresponding encryption key, and using the encryption key to decode the print program ciphertext so asto obtain print program plaintext; and receiving a burning recording command sent by the terminal device by adopting a near-end communication mode, and recording the print program plaintext in the chip in a burning mode. The print program safety burning recording method can realize reutilization for the chip, and ensures safety and reliability in the burning recording process of a print program.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a method for securely burning a printing program, a chip and printing consumables. Background technique [0002] At present, printers mainly include inkjet printers and laser printers. Both inkjet printers and laser printers include the following two parts: the printer host and multiple detachable printing consumables. Each printing supply consists of an ink or toner cartridge and a chip attached to the ink or toner cartridge. During use, the chip communicates with the printer host. The chip is used to store original information such as manufacturer information, model, color, and total amount of ink of the corresponding printing consumables. At the same time, during the subsequent use of power on and off, replacement of printing consumables, and printing, the host computer of the printer will read and write the chip in the printing consumables through the relevant interface w...

Problems solved by technology

[0003] Traditionally, when the number of printed sheets recorded by the chip in the printing consumable reaches a preset threshold (such as 500), the printer will think that the printing consumable has run out of ink or powder and cannot be used any longer; at this time, The chip will be discarded together with the printing consumables, which will cause a waste of chip resources

At the same time, users also need to pay for the chips in purchasing new printing consumables, which will inevitably increase the printing cost of users
