Driving method of thermal printer in POS machine

Abstract

The invention discloses a driving method of a thermal printer in a POS machine, and relates to the technical field of POS machine equipment driving. The thermal printer adopts interrupt-driven. Heating, calculation of printing control parameters and transmission of printed dot matrix data are operated in a parallel mode, that is, when a heating head is heated, the calculation of the printing control parameters and the transmission of the printed dot matrix data are processed in the parallel mode, and the time is saved greatly, the speed is improved directly, the accuracy of printing time is ensured, and thus the printing clarity is ensured. Therefore, according to the driving method of the thermal printer in the POS machine, the clarity and speed of the POS machine thermal printer can be improved at the same time, and needs of use are met.

Description

technical field [0001] The invention relates to the technical field of POS device drive, in particular to a method for driving a thermal printer in a POS machine. Background technique [0002] The sharpness and speed of thermal printers in POS machines are two important performance indicators of POS machines. In some applications, the sharpness and speed of thermal printers are required to be relatively high. [0003] At present, for thermal printers, people usually increase the speed by shortening the heating time, and shortening the heating time will lead to insufficient heating, which will make the printed characters blurred; at the same time, the short heating time will make it too late to cool down. , so that the heat of the previous point affects the following point, making the latter point appear shadow. [0004] Therefore, the resolution and speed of the thermal printer cannot be improved by adopting the above-mentioned technical solution, and thus cannot meet the u...

[0003] At present, for thermal printers, people usually increase the speed by shortening the heating time, and shortening the heating time will lead to insufficient heating, which will make the printed characters blurred; at the same time, the short heating time will make the previous point too late to cool , so that the heat of the previous point affects the following point, making the latter point appear shadow

[0004] Therefore, the adoption of the above technical solution cannot improve the resolution and speed of the thermal printer, and thus cannot meet the needs of use.
