前言感热式印刷机,其原理就是将印字头上的加热元件接触感热记录纸,然后根据印字信息来控制由象素型矩阵所构成的印字头的某些加热元件瞬时放热,使感热记录纸受热发色,最后在纸上形成象素型文字(图1)。这种印刷机的优点是:从原理上克服了击打式印刷机靠机械冲击印字所产生的噪音,而且能够实现快速印刷,和静电等非击打式印刷机相比,记录电压低;无须显影、定影;受热直接发色成象;处理简便;机器结构简单;经济;宜于小型化。因此,成为当前发展非击打式印刷机中较有前途的一种。
Preface Thermal printer, the principle is the printing head on the heating element touch thermal recording paper, and then according to the printing information to control the print head formed by the pixel matrix of some heating elements instant heat, the sense of flu Heat recording paper is heated hair color, and finally form a pixel-type text on paper (Figure 1). The advantages of this type of press are: in principle, overcoming the noise generated by impact impulses by impact impulses, and enabling fast printing, with lower recording voltages than non-impact presses such as static electricity; Development, fixing; direct thermal color image; easy to handle; machine structure is simple; economic; should be small. Therefore, it becomes a more promising one in the current development of non-impact printing machines.
