Problems solved by technology

[0002] At present, the printing accuracy of 58 series thermal printers on the market is mostly 203dpi. On thermal paper with a width of 58mm, the printing operation within the effective printing width range of 48mm is completed. The printing density is 8 dots / mm, and the number of printing dots per line is 384 dots, the printing accuracy is low, so that in personalized applications, the definition of graphic printing is poor, and the printing effect is not good, which is not satisfactory

Abstract

The invention discloses a high-precision thermal printer, and belongs to the technical field of printers. The high-precision thermal printer comprises a machine core and a control unit electrically connected with the machine core; the machine core comprises a machine frame, a paper feeding control mechanism and a heating printing mechanism; the paper feeding control mechanism comprises a rubber roller assembly, a gear assembly and a stepping motor, the rubber roller assembly is rotationally arranged on the machine frame, the stepping motor, the gear assembly and the rubber roller assembly arein transmission connection in sequence, and the stepping motor drives the gear assembly to rotate and drives the rubber roller assembly to rotate; the heating printing assembly comprises a thermal piece assembly, a heat dissipation plate and an elastic piece assembly, wherein the thermal piece assembly is arranged on the machine frame, the heat dissipation plate is arranged on the thermal piece assembly, and the elastic piece assembly is connected with the thermal piece assembly in an abutting mode; and a control unit comprises an MCU control chip and a system state detection circuit connectedwith the MCU control chip. According to the high-precision thermal printer, the printing precision and the printing effect can be effectively improved, and the printing effect is superior to the printing effect of a common 203 dpi model printer on the market.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a high-precision thermal printer. Background technique [0002] At present, the printing accuracy of 58 series thermal printers on the market is mostly 203dpi. On thermal paper with a width of 58mm, the printing operation within the effective printing width range of 48mm is completed. The printing density is 8 dots / mm, and the number of printing dots per line is 384 dots, the printing accuracy is low, so that in personalized applications, the definition of graphic printing is poor, and the printing effect is not good, which is not satisfactory. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a high-precision thermal printer, which can effectively improve printing accuracy and printing effect, and the printing effect is better than the common 203dpi printers on the market. [0004] In ...
