ZPL 打印斜体粗体和下划线

Question

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？请注意，内容是动态的。 请提供 ZPL 代码。

Answer 1

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用法( http://labelary.com/docs.html

Answer 2

没有简单的方法可以在 ZPL 中将文本加粗或斜体。打印机的字体非常基本，不能那样更改。

Answer 3

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。 这两个页面包含有趣的Java代码来编写转换器：

。我仍然不确定转换的CRC部分将来是否会保持不变，因为这可能取决于供应商。
