Problems solved by technology

However, in some industry applications, special code systems are used, and users do not want to disclose the content of the code system. In this case, general-purpose barcode printers cannot print
Similarly for the new code system, the printers listed before it came out can not print it

[0042] Embodiment——Achieving Chinese Sensible Code Printing Method on SATO 408E Printer

[0043] Hanxin code is a new two-dimensional barcode with independent intellectual property rights in my country. It has super Chinese character encoding ability and can represent all Chinese characters stipulated in "Information Technology-Chinese Character Coded Character Set for Information Interchange-Basic Set Expansion" , which is the most efficient way to express Chinese characters in the existing two-dimensional barcodes. Chinese Sensible Code also has high anti-damage and anti-distortion capabilities, and the maximum error correction capability can reach 30%. Chinese Sensible Code also fully considers the representation efficiency of Chinese character information. For the same information content, Chinese Sensible Code is only 90% of the symbol area of ​​the Quick Response Matrix Code and 63.7% of the symbol area of ​​the Data Matrix Code. Hanxin code has broad market application ...

Abstract

The method comprises: connecting a print controller between the main computer and the printer; said print controller is connected to the main computer and printer via a communication port; a new-code encoding program used for encoding the bar code content based on new coding formation is embedded into the print controller; defining a print expansion command used for printing a special bar code; the main computer sends down the print command to the communication port; the print controller receives and analyzes the print command, and sends down a relevant print command to the printer; if it's a normal print command, then directly sending it to the printer; if it's an expansion command, then encoding the print content based on a special encoding format, and generating a image, and then sending the command for printing the image; after receiving the command, the printer completes the print operation.

Description

technical field [0001] The invention relates to a method for expanding the compatible code system of a bar code printer. Background technique [0002] The traditional barcode printer is connected to the printing host as follows: Figure 5 As shown, the printing host and the barcode printer are connected and communicated through a parallel port or an RS232 serial port, and the host controls the printer to print barcode labels. [0003] At present, the mainstream barcode printers only support the printing of the mainstream code system. The built-in mainstream code system encoding program is controlled by the host, and the content to be printed can be encoded and printed according to the specified code system at the position specified by the label. Now, in some industry applications, a special code system is used, and the user does not want to disclose the content of the code system. In this case, a general-purpose barcode printer cannot print. Equally for the code system that...
