Application Technology Of Portable Printer

1. Wired communication

RS232 wired communication technology with a long history. Portable ticket printers and label printers are widely used, but they are generally not used for receiving print data, but for debugging.

Ethernet Ethernet communication, with high transmission speed and convenient access, is used for printer communication interface.

2. USB

Portable office printers and photo printers generally use USB as the wired data communication interface.

3. Telecommunications

Infrared (IrDA), Bluetooth (Bluetooth), WiFi (802.11b/g), rf2.4g wireless, rf433mhz wireless.

Infrared technology was still used in many portable printers before 2007, but with the gradual elimination of infrared technology in notebook computers and mobile phones, there are fewer and fewer printers using infrared technology.

The wireless data communication technology of Bluetooth mainstream portable printer has the advantages of low power consumption and non directionality, but the disadvantages are limited transmission distance and cumbersome early setting and pairing.

WiFi is a technology used by some portable ticket printers and label printers. Its advantages are long transmission distance and non directionality, and its disadvantages are high power consumption for printers that completely rely on batteries.

Rf2.4g wireless belongs to the civil free frequency band. With the maturity of technology and the decline of cost, it has been widely used in the field of computer peripherals and has also been used in the wireless communication of printers. Low power consumption, long transmission distance, and the maximum effective distance is about 30 meters.

Compared with the above higher frequency wireless bands, rf433mhz wireless band has higher penetration. The maximum effective distance is about 100 meters. It is mostly used to build a small-scale private wireless network. Printers can receive requests from mobile office devices within the network at any time to print.
