Abstract

This invention relates to one device and method to realize POS machine parallel data and to output printing, wherein the device is to connect the current POS machine and print machine interface and comprises central process unit and monitor input unit, data memory unit and interface output unit through address and data bus. The said data memory unit is to imbed data memory area and mode matching memory area in operation system area. The printing order and input process module through above application layer to set and update according to printing machine and POS machine.

Description

technical field [0001] The present invention is a device for connecting POS machine (commercial cash register) and printing and its usage method. The device can be applied to the POS parallel port based on IEEE1284 standard to realize receiving and output printing of various data transmission modes. It is a method for large and medium-sized commercial retail enterprises of the application type to realize tax control management. Background technique [0002] At present, in large and medium-sized commercial places, there are various types of POS machines, that is, commercial cash registers. In accordance with the relevant current national standards, in order to strengthen tax management, the data in the tax control memory, invoice memory and tax control IC card in the tax control equipment can be accurately and properly preserved, and should be accurate and consistent with the data received and printed by the printer , this function can be realized by this device. [0003] T...
