Question

我正在尝试使用ZPL II将扩展代码页850字符打印到Zebra S4M。每当一个扩展字符I.E. 使用127我得到一盒不同的灰色阴影而不是实际值。

我正在尝试打印±和°（ALT + 0177和ALT + 0176）。我怀疑它是我试图使用的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，直接从记事本打印会呈现正确的字符，这让我相信它是原始打印机帮助程序类的问题。

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。

示例ZPLII 没有逃脱的角色

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

使用转义字符（尝试过大写和小写）

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

接受的答案中的实际修复将字符国际化（代码 ^ CI27 ）设置为代码页1252.

^FS

Answer 1

是的，阴影框中包含那些字节代码，代码页1252.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为850.从the manual判断，这需要^ CI来选择字符集13.

保持代码页为1252并改变你的字符代码是明智的。字形表位于手册的后面。
