Abstract

The invention discloses a real-time temperature-sensitive printing device. A power supply special for a printer provides power for a temperature-sensitive printing head driving module, a temperature-sensitive printing head and a step motor driving module; a printer logic power supply module provides power for a microcontroller, a sensor driving module, a sensor, a universal serial port (USB) interface circuit and a storage; the temperature-sensitive printing head driving module drives the temperature-sensitive printing head to work, the step motor driving module drives a step motor to run; and the temperature-sensitive printing head driving module, the temperature-sensitive printing head, the step motor driving module, the sensor driving module, the sensor, the USB interface circuit and the storage are all in electric connection with the microcontroller. The power supply special for the printer and the printer logic power supply module respectively provides power for each module in the device, accordingly real-time work of the USB interface circuit is guaranteed, and simultaneously sufficient power is provided for the temperature-sensitive printing head.

Description

technical field [0001] The invention relates to the field of thermal printing, in particular to a real-time thermal printing device. Background technique [0002] The traditional mechanical needle-type printers have large volume, slow printing speed and loud noise, and have gradually withdrawn from the stage of printers. Although the noise of popular inkjet and laser printers is slightly reduced, they are larger in size and do not have the function of real-time printing, which is difficult to meet the needs of some testing instruments such as temperature recorders and medical instruments. [0003] The principle of thermal printers is to coat a light-colored material (usually paper) with a transparent film, and heat the film for a period of time to turn into a dark color (usually black, but also blue). The image is created by heating, which produces a chemical reaction in the film. This chemical reaction is carried out at a certain temperature. High temperatures accelerate...
