ZPL II扩展字符

Question

我正在尝试使用ZPL II将扩展代码页850字符打印到Zebra S4M.每当使用其中一个扩展字符IE ASCII值> 127时,我得到一个不同灰度而不是实际值的框.

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,直接从记事本打印呈现正确的字符,这使我相信它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.

样本ZPLII 没有转义字符

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

逃脱的角色(试过大小写)

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

来自接受的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

Answer 1

是的,阴影框具有代码页1252中的字节代码.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.从手册判断,这需要^ CI来选择字符集13.

保持代码页在1252并改变你的字符代码是明智的.字形表位于手册的后面.
