ZPLⅡ扩展字符

Question

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，我就会得到一盒不同颜色的灰色，而不是实际值。

我试图打印±和°(ALT+0177和ALT+0176)。我怀疑这是我试图使用的RawPrinterHelper (从MS下载的，从CodeProject下载的)，但是我看不出字符代码出了什么问题。

奇怪的是，直接从记事本打印出来的字符是正确的，这让我相信这是原始打印机助手类的问题。

我不想使用原版打印机助教班，所以如果有更好的方法去做，我很高兴看到他们。

没有转义字符的示例ZPLII

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

使用转义字符(上、下两种情况都试过)

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

实际修正从接受的答案设置字符国际化(代码^CI27 27)到代码页1252。

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

Answer 1

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

您必须发送命令才能将代码页切换到850。从手册判断，这需要^CI来选择字符集13。

将代码页保持在1252并改为更改字符代码将是明智的。字形表在手册的后面。
