Method and device for printing bill information

Abstract

The invention discloses a method and a device for printing bill information. The method comprises the following steps of: processing the content information of a bill to be printed to form a character string; representing a '1' module of a binary system by using four printing points to obtain a matrix two-dimensional code of the character string, wherein every two of the four printing points are spaced by one printing blank space; and printing the content information and the matrix two-dimensional code on the bill. By the method and the device, the condition that the bill is punched when the multiplicate bill is subjected to two-dimensional code printing by using a needle printer is effectively avoided, so that the device can be used for performing two-dimensional code verification on a large number of bills, the information capacity of unit area is increased, and the problems in the prior art are solved.

Description

technical field [0001] The invention relates to the field of bill anti-counterfeiting, in particular to a bill information printing method and device. Background technique [0002] Compared with the existing barcodes and digital passwords, the two-dimensional code has the advantages of small printing area and large capacity. The use of the two-dimensional code has become the current trend, but for multi-part bills, it is necessary to use a dot matrix printer for printing . However, in the existing two-dimensional code dot matrix printing, a 2*2 or 3*3 printing dot matrix is ​​used to form a module, and multiple blanks need to be reserved at the same time, which is conducive to the recognition of the printout by the recognizer. Module identification, but this printing method has the following problems: [0003] First of all, because the modules representing "1" need to print 2*2 or 3*3 dots densely, during the printing process, the probability of the bill being easily punct...

Problems solved by technology

[0003] First of all, because the modules representing "1" need to print 2*2 or 3*3 dots densely, during the printing process, the probability of the bill being easily punctured is high, resulting in a low probability of the information on the bill being unrecognizable. high;

[0004] Secondly, because the existing printing method needs to leave a lot of blanks for easy identification, for example, 5*5 cells are required to represent a module, and the 9-pin printer only uses 4 of the cells to print valid information and requires 21 A 24-pin printer only needs 9 cells instead of 16 spaces, so a lot of space is wasted to distinguish each module. Such a large number of blanks reduces the capacity of the two-dimensional code under the same printing area and cannot be used in the data volume. Used when the printing area is large and the printing area is limited
