Problems solved by technology

There are many disadvantages in the way of cable connection. For example, the construction wiring in the early stage requires manpower, material and financial resources. When there are too many printers or computer equipment connected, multiple cables are intertwined, which not only takes up space but is not beautiful, and the cable When the interface encounters collision and pulling, it is easy to cause looseness, which will affect the normal operation of the printer and reduce work efficiency

Abstract

The invention provides a bill printing implementation method and device. The bill printing implementation method comprises the steps that an NFC unit, a WIFI unit, a BT unit and / or USB unit in printing auxiliary equipment receive externally-input bill information through wireless or wired connection; a controller controls the NFC unit, the WIFI unit and / or the BT unit to transmit the bill information to a bill printer through wireless connection, and the bill printer decodes and prints the received bill information. According to the bill printing auxiliary equipment, the equipment provides a plurality of wireless or wired connection manners, and a plurality of wired or wireless technologies such as the WIFI direct wireless technology or the BT wireless technology or the NFC technology or the USB technology are utilized for obtaining bill information; wireless data transmission between the equipment and the bill printer can be achieved, and bill information of the bill printer is transmitted in a variety manner; and the cable access complexity of the bill printer is not increased, an encryption unit and a decryption unit are arranged, and safety of bill information can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of bill printing, in particular to a method and device for realizing bill printing. Background technique [0002] Bill printing is an important link in various commercial activities, and bill printers are also indispensable office equipment in commercial places. Existing receipt printers are all connected to computer equipment through cables, and are operated by commands from the computer equipment, and the receipt information is transmitted to the printer through cables for receipt printing. There are many disadvantages in the way of cable connection. For example, the construction wiring in the early stage requires manpower, material and financial resources. When there are too many printers or computer equipment connected, multiple cables are intertwined, which not only takes up space but is not beautiful, and the cable When the interface encounters collision and pulling, it is easy to cause looseness, whi...
