For a customer, the chip is purchased only once, and the printing program can be downloaded and obtained by delivering a small amount of cost subsequently, so that the cyclic utilization of the chip is realized, and the printing cost is effectively saved. For a chip manufacturer, the continuous profit can be realized by only investing the production cost of the chip once and downloading and acquiring the printing program by paying at the later stage, and the economic benefit of the chip manufacturer is improved.

It will be appreciated that the same chip may be used on different models of printers. For example, when a chip is used in a first printer, a first printing program is used. According to the customer's needs, when the chip is transferred to the second printer, the existing first printing program of the chip needs to be erased, and then the second printing program is burnt to the chip, so that the diversified repeated application of the same chip can be realized.
According to the embodiment of the invention, burning the printing program plaintext into the chip specifically comprises the following steps:
upgrading the original printing program in the chip according to the printing program plaintext; and/or
And formatting the parameters of the original printing program in the chip according to the printing program plaintext.
It should be noted that, when the printer is upgraded, in order to meet the upgrade requirement of the printer, the original printing program in the chip also needs to be upgraded.
It should be noted that the parameters may include the number of sheets to be printed, the remaining amount of ink or powder, the amount used, the number of times of recording printing, the time, and the like. Specifically, when the chip is replaced from the old printing consumable to the new printing consumable, since the number of printed sheets recorded by the original printing program in the chip reaches the maximum (e.g. 500 sheets), the new printing consumable is not used, and the parameters of the original printing program of the chip need to be formatted. For example: the printing number parameter in the printing program is set to be 0, and the printer can know that the printing consumable material is new according to the interaction with the chip, so that normal printing can be realized.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present application is not limited by the order of acts described, as some steps may occur in other orders or concurrently depending on the application. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required in this application.
