Description

Method and system for automatically printing Chinese characters by bar code printer
Technical Field
The invention belongs to the technical field of printing, and particularly relates to a method and a system for automatically printing Chinese characters by a bar code printer.
Background
The zebra printer provides a solution for industrial barcode printing and is widely applied to industrial production. The application scenarios are very many, such as printing the unique serial number of the product (for example, SN: 01234567890), and realizing dynamic printing by using a zebra printer. The operating principle of the zebra printer is that real-time data is converted into ZPLII language by printing software and is dynamically sent to the printer, and then the printer completes the printing work. These data, which are usually composed of numbers or letters, can be directly printed out because the numbers and letters marked in the zpli language are directly recognizable by the printer.
However, if the Chinese barcode needs to be printed, the Chinese code cannot be directly sent to the printer because ZPLII language does not "know" Chinese. The technical scheme for solving the problem is that the object is coded by a ZPLII language, and in the ZPLII language, the object can be coded according to characters or graphic arrays. In the prior art, the printing of the Chinese barcode generally utilizes a barcode editing tool to convert Chinese into a graphic array code according to the characteristics of a picture, then the coded data is sent to printing software, and the printing software sends the data to a printer. However, the bar code editing tool converts the Chinese characters into the graphic array codes according to the picture characteristics by manual operation, so that the printed Chinese characters are fixed. The scheme has the disadvantages that only fixed Chinese can be printed, for example, two characters of black are printed, the black can be prepared in advance in a picture mode during design, the black can be printed only each time, if a batch of products have both black and white, the two characters of white cannot be directly printed, and the black can be replaced by the corresponding code of white manually.

In the zpli language, objects may be coded either in text or in graphic arrays.
The encoded data is output to the target printer via an output module 32. And the target printer acquires and identifies the coded data and executes the bar code printing of the Chinese characters.
Preferably, the query module further includes a template unit, configured to make a basic script template according to the zpli language, and set the feature variable in the basic script template.
The template unit uses ZPLII language to make a basic script template, and sets characteristic variables in the basic script template. And when the printing is executed, calling the basic script module, replacing the characteristic variables in the basic script template with ZPLII language graphic array codes corresponding to the Chinese characters, generating data in a ZPLII language format, and sending the data to a target printer.
According to the technical scheme, the color characteristics of the product are dynamically identified in the production process of the product, and the corresponding bar code label is printed according to the color characteristics of the product, so that convenience is brought to a user, and the production efficiency is improved.
In conclusion, the method and the system for automatically printing Chinese characters by the bar code printer solve the problem that only fixed Chinese bar codes can be printed in the prior art, realize automatic selection of corresponding Chinese characters according to product colors, print corresponding Chinese character bar codes and bring convenience to users.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
