Description
Technical field
The present invention relates to thermal printing field, particularly, relate to a kind of thermal printing apparatus in real time.
Background technology
Traditional mechanical impact printer volume is large, print speed is slow, noise is large, has exited the stage of printer gradually.Although popular ink-jet, laser printer noise slightly reduce, volume possesses more greatly and not the function of real time print, is difficult to meet some testers as moisture recorder, the demand of Medical Instruments etc.
The principle of thermal printer is, on light color material, (normally paper) is covered with layer of transparent film, becomes dark (be generally black, also have blueness) after film being heated a period of time.Image is by heating, produces chemical reaction and generate in film.This chemical reaction carries out at a certain temperature.High temperature can accelerate this chemical reaction.When temperature is lower than 60 DEG C, film needs through quite long, and the time even reaching several years just can become dark; And when temperature is 200 DEG C, this reflection can complete in a few microsecond.
Thermal printer heats selectively on heat-sensitive paper really allocation, just creates corresponding figure thus.Heating is provided by the little electronic heater of on the printhead contacted with thermo-sensitive material.The form of the heater side's of lining up point or bar carries out logic control by printer, when activated, and the figure that just generation one is corresponding to heated elements on heat-sensitive paper.Control the same logic circuit of heated elements, also control paper feed simultaneously, thus can print off figure on whole label or paper.Heat-sensitive paper constitutes a two-dimentional square formation by thermographic little one by one point, and heat-sensitive paper heats by thermal head the object that corresponding row pixel reaches imaging according to certain sequential under the drive of stepper motor.
The resolution ratio of heat-sensitive paper is very high, and the resolution ratio of conventional heat-sensitive paper is every millimeter of 8 points, and therefore subsidiary factory is suitable for showing and printing fine and smooth Wave data, is widely used in industrial data and traces, the occasions such as record.In addition, thermal printer also has the advantages such as print speed is fast, noise is low, reliability is high, writing is clear, type is small and light, can meet the printing requirement of this occasion, therefore widely uses in fields such as instrument of surveying and mapping, POS consumption terminals
Existing USB technical support bulk transfer and real-time Transmission two kinds of patterns, bulk transfer mode realizes easily, and transmission speed is large, and be widely used in life, common equipment is USB laser printer, scanner etc.But this kind equipment is difficult to the competent occasion high to requirement of real-time, and such as real-time waveform is traced.The real-time Transmission pattern of USB is this type of application design just, and be generally used for equipment for customizing, this kind equipment generally pursues high real-time performance.USB real-time Transmission pattern is divided into again low speed/Full-Speed mode and fast mode, maximum 64 byte every millisecond of transmission speed under low speed/Full-Speed mode, and can reach every 1/8 millisecond of 1024 bytes in high speed mode.Be very suitable for requiring high occasion to real-time performance.Invention 200810166228.2 discloses a kind of energy-storing USB thermal sensitive printer, this invention achieves a kind of thermal printer of USB interface, this USB interface is also powered to printer while providing communication function, in order to solve the problem of USB interface maximum power supply 2.5W deficiency, this invention utilizes USB to capacitance energy storage, is powered to thermal printing head by electric capacity.But the power supply of USB is limited after all, the method can only be used for undersized printer, can not be sent out application by wide.
