C# ZPL II扩展字符

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，即ASCII值>127时，我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）。我怀疑这是我试图使用的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，我非常乐意看到它们

样本ZPLII 没有逃脱的魔咒

        DOCINFO documentInformation = new DOCINFO();
        int printerBytesWritten = 0;
        documentInformation.printerDocumentName = printerJobName;
        documentInformation.printerDocumentDataType = "RAW";

        WritePrinter(handleForTheOpenPrinter, rawStringToSendToThePrinter, rawStringToSendToThePrinter.Length,

        EndDocPrinter(handleForTheOpenPrinter);
        ClosePrinter(handleForTheOpenPrinter);

}

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
^XZ

是的，阴影框具有代码页1252中的字节码。它无疑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。从中判断，这需要^CI选择字符集13

将代码页保持在1252，改为更改字符代码是明智的。glyph表在手册的后面。

谢谢Hans-我会在早上试一试，看看这是否解决了问题
