Printer is one of the output devices of the computer. It is used to print the processing results of the computer on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printer, according to the printing element on the paper whether there is a hit, hit printer and non - hit printer. According to the print character structure, fractal word printer and dot matrix character printer. According to the way a line of words is formed on paper, a string printer and a line printer are divided. According to the technology used, split-column, spherical, inkjet type, thermal type, laser type, electrostatic type, magnetic type, LED type printers.

Testing standard

EMC Directive (2014/30/EU), LVD Low Voltage Directive (2014/35/EU) and MD Machinery Directive (2006/42/EC) are generally required for printer CE certification.

Printer CE certification standard:
Basic concepts and general design aspects of ISO mechanical safety standards (basic terms, methods).
Basic concepts and general design principles of ISO mechanical safety standards (Technical principles and instructions).
