【问题描述】：
我需要打印带有动态内容的 ZPL。
我需要你的帮助。我是动态内容，请帮助我。
这个词可以打印吗？注意内容是动态的。 请提供 ZPL 代码。

我知道它很旧，但如果其他人有类似的问题，你已经尝试过了吗？ stackoverflow.com/questions/27377181/…

【问题描述】：
如果你想输入粗体，你可以使用这个
^FO340,128^FDbold^FS ^FO339,128^FDbold^FS
另一个选项（下划线、斜体和粗体的外部字体使用） http://labelary.com/docs.html
【讨论】：
没有简单的方法可以使用 ZPL 来粗体或斜体文本。打印机的字体非常基本，不能这样更改。

现在有什么可以做斜体的吗？
复杂的字体设置（斜体、粗体、衬线）实际上作为压缩图像发送到 ZPL 打印机（您可以使用 ZebraDesigner 进行检查）。 该格式称为 Z64，它基于 LZ77。 这两个页面包含用 Java 编写转换器的有趣代码：

https://gist.github.com/trevarj/1255e5cbc08fb3f79c3f255e25989a18
...我仍然不确定转换的 CRC 部分是否会在未来保持不变，因为这可能取决于供应商。
这是第一个脚本的 Python 端口：
