Problems solved by technology

However, the existing printing technology uses the principle of thermal transfer to print the two-dimensional barcode on the paper, so except for the two-dimensional barcode printed on the first page, the other pages are not subject to pressure due to no pressure. Two-dimensional barcodes will be developed, and such multi-part bills are not allowed to be used because the content of the first part is different from other parts

Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] figure 1 It is a flowchart of a method for printing two-dimensional barcodes on multi-part bills with a dot matrix printer provided by the present invention. The multi-part bill described in the present invention is composed of the first part and more than one other part with copying function, and the other parts except the first part are all made of carbonless copying paper, and the material of the carbonless copying paper It is relatively fragile and easily damaged when it is subjected to intensive pressure. The carbon ink coated on its upper surface can be developed at the position subjected to external pressure, thereby leaving marks on the paper. Usually, the information is printed on the surface of the...

Abstract

The invention relates to a method for printing a two-dimensional bar code on a multi-copy bill by a stylus printer. The method comprises the following steps: the step 1 of judging whether the resolution of the stylus printer is a real image printing resolution of the stylus printer, if yes, executing the step 2, or setting the resolution of the stylus printer into the real image printing resolution of the stylus printer and executing the step 2; the step 2 of judging whether parameters of the two-dimensional bar code to be printed are related to the real image printing resolution of the stylus printer, if yes, executing the step 3, or setting the parameters of the two-dimensional bar code to ensure the parameters related to the real image printing resolution of the stylus printer and executing the step 3; and the step 3 of printing the two-dimensional bar code and bill characters on a first copy of the multi-copy bill by the stylus printer. Due to the utilization of the technical scheme adopted by the invention, the two-dimensional bar code can be printed on all the copies of the multi-copy bill; and the method is beneficial to accurately reading the two-dimensional bar code by a computer.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a method for printing two-dimensional barcodes on multiple bills with a dot matrix printer. Background technique [0002] Using paper documents to transmit information means that the computer system controls the printer to print information symbols on the paper documents. These information symbols include Chinese characters, numbers, letters, punctuation marks, one-dimensional barcodes, two-dimensional barcodes, etc. In this way, when performing various follow-up operations based on the information on the paper document, it is only necessary to read the above information symbols. With the development of computer image processing technology, more and more paper documents are read by computers, which greatly reduces the workload of manual reading. [0003] As a paper document, multi-part bills can carry various sales information, and operations such as tax declaration and ...
