打印ESCPOS图像c#

Question

因此，我正在构建一个程序，通过服务发送的命令在escpos打印机中打印。我管理了所有的东西，文本，对齐，字体大小等。现在我需要打印一个以八位位流发送的图像，我该怎么做？我什么都试过了

图像字符串为////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAH///8AAAAAAAAAAAAAAAAA//4P/////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH8AAAAAAAAAAAAAAAAAAAA//4AAH///B//wAH8AAAAAAAAAAAEAAAAAAAA//4AAD///B//wAH8AAAAAGAAAAD/4AA///gA//4AAD///B//wAH8AAAAAHAAAAP/+AA///gA//4AAD///B//wAH8AAAAAPAAAAf//AA///gA//4AAD///B//wAH8AAAAAPgAAA///gA///gA//4P/////B//wAH8AAAAAfgAAB/g/AAAfAAA//4P/////B//wAH8AAAAAfwAAD+AOAAAfAAA//4P/////B//wAH8AAAAA/wAAD8AAAAAfAAA//4P/////B//wAH//+AAA/4AAH4AAAAAfAAA//4P/////B//wAH//+AAB/4AAHwAAAAAfAAA//4AP////B//wAH//+AAB98AAPwAAAAAfAAA//4AH////B//wAH//+AAD58AAPwAAAAAfAAA//4AH////B//wAH//+AAD5+AAPwAAAAAfAAA//4AH////B//wAH8AAAAHw+AAPgAAAAAfAAA//4AH////B//wAH8AAAAHw/AAPwAAAAAfAAA//4AP////B//wAH8AAAAPgfAAPwAAAAAfAAA//4P/////B//wAH8AAAAPgfAAPwAAAAAfAAA//4P/////B//wAH8AAAAf//gAH4AAAAAfAAA//4P/////B//wAH8AAAAf//gAH4AAAAAfAAA//4P/////B//wAH8AAAA///wAH8AAAAAfAAA//4P/////B//wAH8AAAA///wAD+AOAAAfAAA//4P/////B//wAH8AAAB///4AB/w/AAAfAAA//4P/////B//wAH8AAAB8AD4AA///gAAfAAA//4P/////B//wAH8AAAD8AB8AAf//AAAfAAA//4P/////B//wAH8AAAD4AB8AAP/+AAAfAAA//4P/////B//wAH4AAAD4AA+AAD/4AAAfAAA/////////B//wAAAAAAAAAAAAAAPAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA

I was trying this
 oby = new List<byte>();
            oby.Add(Convert.ToByte(0x1B));
            oby.Add(Convert.ToByte(0x2A));
            oby.Add(Convert.ToByte(33));
            Bytes = PrintExtensions.AddBytes(Bytes, oby.ToArray());
            Bytes = PrintExtensions.AddBytes(Bytes, System.Text.Encoding.ASCII.GetBytes("////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAAAAAAAAAAAAAAAAAAAAAAA//4P/////B//wAH///8AAAAAAAAAAAAAAAAA//4P/////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH///8AAAAAAAAAAAAAAAAA/////////B//wAH8AAAAAAAAAAAAAAAAAAAA//4AAH///B//wAH8AAAAAAAAAAAEAAAAAAAA//4AAD///B//wAH8AAAAAGAAAAD/4AA///gA//4AAD///B//wAH8AAAAAHAAAAP/+AA///gA//4AAD///B//wAH8AAAAAPAAAAf//AA///gA//4AAD///B//wAH8AAAAAPgAAA///gA///gA//4P/////B//wAH8AAAAAfgAAB/g/AAAfAAA//4P/////B//wAH8AAAAAfwAAD+AOAAAfAAA//4P/////B//wAH8AAAAA/wAAD8AAAAAfAAA//4P/////B//wAH//+AAA/4AAH4AAAAAfAAA//4P/////B//wAH//+AAB/4AAHwAAAAAfAAA//4AP////B//wAH//+AAB98AAPwAAAAAfAAA//4AH////B//wAH//+AAD58AAPwAAAAAfAAA//4AH////B//wAH//+AAD5+AAPwAAAAAfAAA//4AH////B//wAH8AAAAHw+AAPgAAAAAfAAA//4AH////B//wAH8AAAAHw/AAPwAAAAAfAAA//4AP////B//wAH8AAAAPgfAAPwAAAAAfAAA//4P/////B//wAH8AAAAPgfAAPwAAAAAfAAA//4P/////B//wAH8AAAAf//gAH4AAAAAfAAA//4P/////B//wAH8AAAAf//gAH4AAAAAfAAA//4P/////B//wAH8AAAA///wAH8AAAAAfAAA//4P/////B//wAH8AAAA///wAD+AOAAAfAAA//4P/////B//wAH8AAAB///4AB/w/AAAfAAA//4P/////B//wAH8AAAB8AD4AA///gAAfAAA//4P/////B//wAH8AAAD8AB8AAf//AAAfAAA//4P/////B//wAH8AAAD4AB8AAP/+AAAfAAA//4P/////B//wAH4AAAD4AA+AAD/4AAAfAAA/////////B//wAAAAAAAAAAAAAAPAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA/////////B//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA//4AAAAAAB//wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA////////////wAAAAAAAAAAAAAAAAAAAAAAA"));

我试了更多，但我不认为它适合这个文本区域

Answer 1

您必须在oby.Add (Convert.ToByte (33));和图像数据之间以2字节为单位指定位图像的宽度。

请参考以下内容。

相应的页面是日语的。

ESC *

ESC *m nL nH d1 ...dk

例如，假设变量ImageWidth包含宽度值，它将如下所示。

oby.Add(Convert.ToByte(0x1B));
oby.Add(Convert.ToByte(0x2A));
oby.Add(Convert.ToByte(33));
oby.Add(Convert.ToByte(ImageWidth & 0xFF));
oby.Add(Convert.ToByte((ImageWidth & 0xFF00)>>8));
Bytes = PrintExtensions.AddBytes(Bytes, oby.ToArray());
