介绍一种利用低端电子秤结合LP-50标签打印机设计标签打印系统,讨论硬件改造的原理和软件设计的过程,解决低端电子秤无法打印标签的问题。该方案能够使用户自由地设计标签模板和编辑产品信息。上位机软件经串口把标签代码信息下载到下位机存储器上,用户只需通过按键选择相应的标签模板就可以由下位机串口把打印信息输出给打印机打印标签。
This paper introduces a label printing system using low-end electronic scales combined with LP-50 label printer to discuss the principle of hardware remodeling and the software design process to solve the problem that low-end electronic scales can not print labels. The program gives users the freedom to design label templates and edit product information. PC software through the serial port to the label code information downloaded to the next crew memory, the user simply by pressing the button to select the appropriate label template by the next crew to print the information output to the printer print label.
