Problems solved by technology

[0002] Printers have been widely used in various fields such as office, industry or commerce, and are used to print required documents or other content. Traditional printers have low precision and do not have the function of dust removal, so they cannot be used in applications that require high printing precision. In some industrial fields, if there is a lot of dust on the printing paper, it will affect the printing effect, easily cause wear to the printing roller and other devices, reduce the service life of the equipment, and easily cause paper jams
