Novel printing equipment power supply unit circuit

Technical Field

The utility model relates to a power supply unit device circuit technical field specifically is a novel printing apparatus power supply unit device circuit.

Background

A printer is one of the output devices of a computer for printing the results of a computer process on an associated medium. The indexes for measuring the quality of the printer comprise three items: print resolution, print speed and noise. There are many types of printers, and an impact printer and a non-impact printer are classified according to whether or not a printing element strikes paper. Full-font character printers and dot matrix character printers are classified according to the character structure to be printed. A line printer is divided into a serial printer and a line printer in such a manner that a line character is formed on a paper. According to the adopted technology, the printer is divided into a column type, a spherical type, an ink jet type, a thermal type, a laser type, an electrostatic type, a magnetic type, a light emitting diode type and the like.

The rapid development of the internet has led to the expectation that the paperless era will come and the last day of the printer will come. Whereas global paper consumption is growing at a doubling rate each year, printer sales are increasing at speeds approaching 8% on average. All of them indicate that the printer will not disappear, and will develop more and more quickly, and the application field is wider and wider. From the first global printer in 1885 to the later various pin printers, inkjet printers and laser printers, which were popular in different times, today we looked for a historical footprint, reviewed the brilliance history of inkjet printers from three aspects, technology, brand and product, application market and target consumer, with a simple analysis of the future development trends of jet printing.
