我正在尝试使用 ZPL II 将扩展代码页 850 个字符打印到 Zebra S4M。每当使用一个扩展字符 IE ASCII 值 > 127 时,我都会得到一个不同灰度的框,而不是实际值。

我正在尝试打印 ± 和 °(ALT+0177 和 ALT+0176)。我怀疑它是我正在尝试使用的 RawPrinterHelper(从 MS 下载,另一个从 CodeProject 下载)但是我看不出字符代码哪里出错了。

奇怪的是,直接从记事本打印会呈现正确的字符,这让我相信这是原始打印机助手类的问题。

我不喜欢使用 Raw Printer Helper 类,所以如果有更好的方法,我很高兴看到它们。

SAMPLE ZPLII 没有转义字符

^XA
^FO30,200^AD^FH,18,10^FD35 ± 2 ° ^FS
^FS
^XZ

使用转义字符(尝试大写和小写)

^XA
^FO30,200^AD^FH,18,10^FD35 _b0 2 _b1 ^FS
^FS
^XZ

已接受答案的实际修复将字符国际化(代码^CI27)设置为代码页 1252。

^XA
^FO30,200^AD^CI27^FH,18,10^FD35 _b0 2 _b1 ^FS
^FS

是的,阴影框有这些字节代码,在代码页 1252 中。毫无疑问,这是打印机的默认代码页,1252 是西欧和美洲的 Windows 代码页。

您必须发送命令将代码页切换到 850。从手册来看,这需要 ^CI 选择字符集 13。

将代码页保持在 1252 并改为更改您的字符代码将是明智的。字形表在手册的后面。
