[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on the paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical printers, spherical printers, inkjet printers, thermal printers, laser printers, electrostatic printers, magnetic printers, light-emitting diode printers and other printers.

[0003] A printer is a printing device that prints and dyes by jetting ink. During printing, the printed object is positioned on a placement platform, and the inkjet carriage performs inkjet printing on the printed object on the placement platform. The placement platform can be a suction platform for carrying and fixing the printed object. Before or during printing, the suction platform generates suction to fix the object. The suction platform of the existing printer directly extracts the air in the suction box through the exhaust fan, and the conveyor belt is all attached to the platform.
