ZPL II扩展字符

Question

我正在尝试使用ZPL II到斑马S4M打印扩展代码的850个字符。每当使用一个扩展字符之一即ASCII值> 127时，我就会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，另一个是从Codeproject下载的），但是我看不到字符代码在哪里出错。

奇怪的是，直接从记事本上打印出正确的字符，这使我相信原始打印机助手类是一个问题。

我与使用原始打印机助手类无关，因此，如果有更好的方法，我很乐意看到它们。

样品zplii没有逃脱的炭

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

带有逃脱的字符（在上箱和下箱都尝试过）

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

接受的答案的实际修复 设置角色国际化（代码 ^CI27 ）到代码第1252页。

^XA

^FS
^XZ

Answer 1

是的，阴影框在第1252页中具有这些字节代码。毫无疑问，这是打印机的默认代码页面，1252是西欧和美洲的Windows代码页面。

您必须发送一个命令才能将代码页切为850。从 手册, ，这需要 ^ci选择字符集13。

将代码页面保持在1252并更改字符代码是明智的。字形桌子在手册的背面。
