Embodiment approach 1

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0030] figure 1 It is a diagram showing the configuration of the printing system 1 to which the embodiment of the present invention is applied. The printing system 1 constitutes one form of a so-called POS system used in various stores such as retail stores. The printing system 1 includes, for example, a POS terminal 2 installed at a cash register of a store, a printer 3 (printing device) connected to the POS terminal 2 to print receipts (receipts), and a receipt history server 6 (external device, server device). The communication network 10 is a communication line connecting the printer 3 and the receipt history server 6 so as to enable mutual data communication, and the communication network 10 is, for example, a LAN installed in a store. The communication network 10 may be a wide-area communication network such as the Internet. In this case, the printers 3 installe...

Embodiment approach 2

[0088] In addition, the above-mentioned embodiment shows an example to which this invention was applied, and this invention is not limited to these embodiment. For example, in the above embodiment, the structure of sending the print data and the unique code to the receipt history server 6 every time the printer 3 prints a receipt has been described as an example, but the present invention is not limited thereto, and may be Send print data and unique code collectively after printing multiple receipts. In this case, there is no problem as long as the print data and the unique code are associated with each receipt. In addition, the print data and the unique code transmitted to the receipt history server 6 may be stored in the receipt data storage unit 43 for a predetermined period of time. Furthermore, when the printer 3 transmits to the receipt history server 6, the unique code may be encrypted and transmitted. In addition, the code generating unit 33 may perform a process of ...

Abstract

To prevent forgery of printed matter using a simple configuration that can be easily introduced even into an existing system, a printer (3) for printing receipts on the basis of printing data sent from a POS terminal (2) is provided with: code-generating section (33) for generating a unique code that is unique for each receipt on the basis of printing data; a print control section (31) and a printing unit (45) for printing a receipt on the basis of the printing data and printing a unique code on the receipt; and a code-transmitting section (34) for outputting the unique code to a receipt history server (6).

Description

technical field [0001] The present invention relates to a printing device and a printing system. Background technique [0002] Conventionally, there is known a device that prints anti-counterfeit information on printed matter (for example, refer to Patent Document 1). The device described in Patent Document 1 prints encrypted information that encrypts part of the printed checkout information using invisible ink when printing a receipt by a receipt printing device connected to a POS terminal. The encrypted information is read and decrypted by a dedicated scanner, and the authenticity of the receipt is determined based on whether the content of the decrypted checkout information is appropriate. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-20439 [0004] In the configuration described in Patent Document 1, encrypted information is used for anti-counterfeiting, and decryption is required for judging authenticity. Therefore, since the processing ...
