Abstract

The invention relates to a control method and device of a thermal printer, a controller and a control system. The method comprises the following steps: receiving operation data of a user on the thermal printer, and determining a to-be-executed current working mode according to the operation data, where the current working mode comprises a resistance value approval mode and a normal printing mode; if the resistor resistance value approval mode is executed, obtaining the actual voltage value, collected by the sampling chip, of each printing head resistor; calculating an actual resistance value of a printing head resistor and a resistance difference value between the actual resistance value and a factory set average resistance value by utilizing the actual voltage value and combining a power supply voltage value and a divider resistance value of the thermal printing head; if the normal printing mode is executed, using the actual resistance value, the resistance difference value and the density of the to-be-printed image for calculating the heating duration of the to-be-heated printing head resistor; and controlling the heating duration of resistor heating of the printing head. According to the method, the heating duration of the printing head resistor is accurately controlled, and the error between a printed image and a source image is reduced.

Description

technical field [0001] The invention relates to the technical field of thermal printers, in particular to a control method, device, controller and control system for thermal printers. Background technique [0002] In the process of printing film, thermal printers print images onto heat-sensitive materials through the resistance heating in the thermal print head. Each minimum heating unit of the thermal print head is composed of extremely small print head resistors. However, due to the processing technology, there is a resistance value error between each print head resistor, which will directly affect the clarity of the printed target image. Spend. [0003] The current production process of the thermal print head cannot realize the effect that the resistance values ​​of the print head resistors in the thermal print head are consistent, and cannot eliminate the resistance value error. In this case, the target image will appear black or white, which will lead to the inconsist...
