POS Printer Chile were born out of laser phototypesetting technology in the late 1980s and became popular in the mid 1990s. It is a Bluetooth Printer China output equipment combining laser scanning technology and electronic photography technology. Its basic principle is from binary data by computer information, through the video controller is transformed into video signal, again by video interface/control system, the video signal is converted into a laser drive signal, and then produced by the laser scanning system with character information of laser beam, finally make the laser beam by the electrophotographic system imaging and transfer to the paper. Compared with other printing equipment, the laser printer has the advantages of fast Printer Manufacturers speed and high imaging quality. But the cost is relatively high.

The composition, design structure, control methods and components of the control devices and components required by the working process of laser printers will vary from manufacturer to manufacturer.

Mini Portable Printer a laser beam, the mirror into the acousto-optic deflection modulator, at the same time, by the binary from computer graphic dot matrix information, from the interface to the glyph generator, form the glyph of binary pulse information needed, produced by synchronizer signal control 9 high frequency oscillator, then through frequency synthesizer and add to the acousto-optic modulator, a power amplifier for modulation by mirrors into the laser beam. The modulated light beam is shot into the multi-facet rotation mirror, and then it is focused by the wide-angle focusing mirror to the surface of the optical drum (toner), so that the angular velocity scan becomes linear velocity scan, and the whole scanning process is completed.
