The invention has advantages such as effectively reducing manpower and material resource cost of a printing service area and promoting the user experience.

Description

technical field [0001] The invention relates to a printing system, in particular to a self-service printing system based on VLC-Zigbee fusion communication technology. Background technique [0002] VLC technology, as an emerging wireless communication technology that uses light-emitting devices to emit high-speed bright flashing light signals to achieve information transmission, has the advantages of green environmental protection, no electromagnetic interference, high data transmission rate, low power consumption, and high safety performance. [0003] Traditional printers are connected to user terminals through wired interfaces (such as parallel ports, serial ports, USB or Ethernet), which are more suitable in the era when desktop terminals dominate. However, with the increasing number of business devices, the data lines between devices The connection is easy to confuse. At the same time, the microprocessor has very high requirements on the data line interface. Once the dat...

[0003] Traditional printers are connected to user terminals through wired interfaces (such as parallel ports, serial ports, USB or Ethernet), which are more suitable in the era when desktop terminals dominate. However, with the increasing number of business devices, the data lines between devices The connection is easy to confuse. At the same time, the microprocessor has very high requirements on the data line interface. Once the data line is damaged or the data interface is loose during the printing process, it will cause serious consequences.

[0004] In view of the limitations of wired transmission, domestic and foreign industries have proposed various printing systems for wireless data transmission, such as infrared, Bluetooth, WIFI, RF2.4G wireless, RF433MHZ wireless, etc., although these wireless communication technologies can reduce the number of wired cables to a certain extent. However, the use of these technologies to realize wireless communication has disadvantages such as unsafe communication signals, electromagnetic interference, large system power consumption, high system installation costs, high labor costs, and limited spectrum width.
