如何在c＃热敏打印中使用EPSON / POS打印机命令？ [英] how to use EPSON/POS printer commands in c# thermal printing?

问题描述

我想用c＃中的ESC / POS命令设置字体大小，方法是将其改为十六进制值。使用escape作为



bw.Write（AsciiControlChars.Escape）。



但是当我尝试使用改变字体大小时没有得到，



bw.Write（AsciiControlChars。 Escape +。+（byte）'！'+。+ AsciiControlChars.Line）;

bw.Write（hai）;

class如下，



命名空间PurchaseDetailsPrint

{



公共静态类AsciiControlChars
{

public const char Escape =（char）0x1B;



public const char Horizo​​ntalTab =（char）0x09;



public const char Line =（char）0x38;



}

}



我的打印机是EPSON TM-T81收据

推荐答案

您需要使用额外的反斜杠。看看这里：

在C＃中转义：字符，字符串，字符串格式，关键字，标识符 [ ^ ]



祝你好运！

You need to use an extra backslash. Have a look here:
Escaping in C#: characters, strings, string formats, keywords, identifiers[^]

Good luck!
