如何使用 Qz Tray 重新打印 PDF417？

Question

我有一个可以打印文本的 Qz Tray 实例，但我对如何从字符串生成 pdf417 条形码有些迷茫。

非常感谢任何指导。

Answer 1

最后我将 PDF417 生成为图像，然后使用 QzTray 提供的原始图像打印进行打印。

Answer 2

如果您想避免使用光栅图形，某些语言（例如 ZPL）支持 PDF417。以下是示例 directly from the Zebra site:

使它适应 QZ 托盘非常简单...

var config = qz.configs.create("ZDesigner");
var data = [
   "^XA^BY2,3\n", 
   "^FO50,50^B7N,5,5,,83,N\n",
