As shown in fig. 1, a first embodiment of the present invention provides a printing power control method, which can be executed by a printer, specifically, by one or more controllers in the printer, and at least includes the following steps:
s101, acquiring total heating power required by the printing head to print the current content at one time; wherein the total heating power required by the current content is positively correlated with the number of points that the current content needs to be heated.
In this embodiment, the printer is provided with a printing medium, a conveying device that conveys the printing medium, a printing head that performs printing, a controller that controls the printing head to move, and a power supply connected to the controller. Wherein the printhead includes a series of selectively actuatable heating elements arranged in an array and selectively actuatable by the controller to present current print content on the print medium.
In this embodiment, the current content is written in advance in a buffer memory of the printer, and the printer controls the driving of the heating element according to the current content. In the printing process, a plurality of heating elements heat simultaneously, and when the number of points needing to be heated is larger, the number of the driven heating elements is larger, so that the total heating power is increased.
In this embodiment, the total heating power required for the printhead to print the current content at once is obtained by the following equation:
P1＝(U2/R)*dot
wherein, P1Is the total heating power; u is the system voltage; r is the resistance of the heating element on the printhead; dot is the number of points to be heated of the current content, dot is less than or equal to dpi, and dpi is the maximum printing point number of the printing head.
And S102, judging whether the total heating power is greater than the rated power of the adapter.
S103, when the total heating power is larger than the rated power, acquiring the residual charge capacity of the capacitor on the circuit board.
In this embodiment, whether the adapter can satisfy the power load of the current print content is determined by comparing the total heating power with the rated power of the adapter. When the total heating power is less than the rated power, the heating of a plurality of heating elements on the printing head can be controlled at the total heating power so as to print the current content at one time without causing overload of the adapter; when the total heating power is greater than the rated power, it is necessary to control the printing power according to the remaining charge capacity of the capacitor on the circuit board.
In this embodiment, a capacitor is disposed on a circuit board of the controller, and the capacitor can be used for storing electric quantity and releasing electric quantity. When the capacitor on the circuit board is fully charged, the maximum charge capacity X of the capacitor is obtained by the following formula:
X＝0.5*C*U2
wherein C is the capacitance value connected with the two ends of the power supply; u is the system voltage.
During printing, the capacitor is constantly charged and discharged, and thus its remaining charge amount varies while floating between 0 and X.
Wherein, after one printing is completed, the calculation formula of the remaining battery capacity is as follows:
X2＝X1+(P-P1)*T；
wherein, X2Residual capacity of capacitor after printing, X1The residual charge capacity before printing is shown, and P is the rated power of the adapter; t is the heating time of the heating element.
It can be seen that when the power rating of the adapter is greater than each heating power, the capacitor is in a charged state (but cannot be greater than the maximum charge capacity X) at the time of the current printing, and when the power rating of the adapter is less than each heating power, the capacitor is in a discharged state at the time of the current printing.
And S104, judging whether the residual electric storage capacity is larger than a preset threshold value or not.
And S105, when the residual charge capacity is smaller than or equal to the threshold value, controlling the heating of a preset heating element on the printing head by heating power smaller than or equal to the rated power so as to print the current content at least twice.
In this embodiment, when the remaining charge amount is less than the threshold value, indicating that the remaining charge amount of the capacitor has failed to satisfy the printing load, the printing power is reduced by reducing the number of dots per printing, and the heating of the predetermined heating element on the print head is controlled at the heating power equal to or less than the rated power. Since the total heating power required to print the current content at one time is greater than the rated power, the current content needs to be printed at least twice in divided.
In one specific embodiment, the heating of predetermined heating elements on the printhead is controlled at a heating power equal to the rated power of the adapter tape, e.g., when it takes at least 2 prints of the current content. In the first N heating processes, a part of the dots are printed at the rated power according to the current content, and the printing of the last part of the dots is finished at the residual power (the total heating power-N × the rated power) in the first N +1 printing processes.
In another specific embodiment, the total heating power may be equally divided into a plurality of portions, and one portion of the total heating power is used for printing each time, which are within the protection scope of the present invention and are not described herein again.
In addition, as can be seen from the above, in this case, since the heating power is equal to or less than the rated power each time, the capacitor is in a charged state, that is, the remaining capacity increases to meet the demand for subsequent printing.
And S106, when the stored electric quantity is larger than the threshold value, controlling the heating of a plurality of heating elements on the printing head by adopting at least the total heating power according to the simultaneous power supply of the adapter and the capacitor so as to print the current content at one time.
In this embodiment, when the remaining charge capacity is greater than the threshold, it indicates that the remaining charge capacity of the capacitor is sufficient for the printing load, and at this time, when the printer controls the heating of the plurality of heating elements on the print head with the total heating power, the printing power is not limited, and printing is performed according to the total heating power corresponding to the actual number of dots that needs to be heated according to the current content, so that all the current content is printed at one time.
It can be seen that in this case, since the heating power (equal to the total heating power) is greater than the rated power each time, the capacitor is in a discharged state, i.e., the remaining charge amount is reduced.
However, considering that the situation that the printer continuously prints with power greater than the rated power (the current print content has many black blocks) is less, the remaining charge capacity can be timely supplemented in the next printing in most cases, so that the printing in most cases is finished at one time, that is, by the printing power control method of the embodiment, the adapter of the embodiment does not need to adapt to the maximum printing power of the printer, and the faster printing can be realized on the premise of not increasing the performance requirement of the adapter and the overall cost of the printer by only meeting the requirement of the average heating power.
