ZPL II扩展字符

Question

我试图使用ZPL II打印扩展代码页850个字符到Zebra S4M。每当其中一个扩展字符I.E.使用ASCII值> 127我得到一盒不同的灰色阴影，而不是实际值。

我在打印±和°（ALT + 0177和ALT + 0176）。我怀疑它正在尝试使用的RawPrinterHelper（从MS下载，另一个来自CodeProject），但是我无法看到字符代码出错的地方。

奇怪的是，从记事本直接打印呈现正确的字符，这导致我相信它是原始打印机助手类的问题。

我并不打算使用Raw Printer Helper类，所以如果有更好的方法，我很乐意看到它们。

样品ZPLII 没有逃脱字符

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

随着转义字符（尝试都大写和小写）

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

从接受的答案实际修复的字符集国际（代码^CI27）到代码页1252

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

Answer 1

是的，阴影框有那些字节代码，在代码页1252哪些无疑是打印机的默认代码页，1252是西欧和美洲的Windows代码页。

你必须发送一个命令代码页转换到850从the manual来看，需要^ CI选择字符集13

在1252保持的代码页和改变你的字符代码将是明智的。字形表位于手册的后面。
