C# 将CPCL发送到Zebra打印机的.NET代码不';不打印特殊字符
我想创建一个简单的.NET应用程序,它将读取CPCL并将其发送到Zebra Printer。我发现这篇文章()帮助我使用了RawPrinterHelper类。但当内容打印到label时,希腊字符等特殊字符无法正确显示。 这是CPCL代码:C# 将CPCL发送到Zebra打印机的.NET代码不';不打印特殊字符,c#,.net,zebra-printers,C#,.net,Zebra Printers,我想创建一个简单的.NET应用程序,它将读取CPCL并将其发送到Zebra Printer。我发现这篇文章()帮助我使用了RawPrinterHelper类。但当内容打印到label时,希腊字符等特殊字符无法正确显示。 这是CPCL代码: ! 0 200 200 320 1 PW 384 TONE 0 SPEED 3 CENTER BARCODE-TEXT 7 0 5 BARCODE 128 1 1 150 0 20 {0} TEXT 7 0 0 250 ΦΡΕΝΑ PRINT 这是.net代

如果有任何帮助,我们将不胜感激。谷歌为您搜索…,然后搜索到您需要的内容。本手册适用于zpl语言,但我使用的是cpcl…您应该不会花太多时间找到正确的…打印机上是否安装了该字体?我认为默认字体不包括希腊字符。。。
