Therefore, the resolution of the character point is high, and the printing quality is high and clear. Flexible and convenient to change character sizes and fonts. Plain paper is used for printing, and this typewriter can also be used to print directly on certain products. There is no mechanical wear during the formation of characters and graphics, and the printing energy consumption is small. Print speeds up to 500 characters per second. Widely used are charge control type (high pressure type) and random ink jet type (negative pressure type) inkjet technology, and dry inkjet printing technology has appeared. 2 thermal printers.

The heat generated by the pulse current flowing through the resistance of the print head is transferred to the thermal paper to be thermally discolored, thereby printing characters and images. The main features are no noise, light and small structure, and clear printing. The disadvantage is that the speed is slow and the writing is poor.
