Send escape sequence to receipt printer

[gillesnebel]

Hi,

I'm building a small POS-Application that prints receipts to EPSON TM-88iii. To print these receipts I actually send raw data to the printer using Visual Basic .NET C#(Microsoft Q322090).
See:

http://support.microsoft.com/default.aspx?scid=kb;en-us;322090

My problem is, that I want to insert Paper Cut in C# and that I don't know how to send the EPSON escape sequences ESC/POS to the printer.. I tried to insert different pieces of code into my string, but it doesn't work.

Can somebody help me please

Thanks very much

Put those bytes into a byte array, then pass them to the GetString method of the ASCIIEncoding class.

This ought to work, as the ASCIIEncoding class will translate values from U+0000 to U+007F

Hi chiph,

Thanks for your answer. I tried to add the mentionend ASCIIEncoding Class but I couldn't make it work :-(

Can you give me a code example basing on Microsoft Thread?

Thanks very much

Try something like this

byte[] b = new byte[] { 0x1B, 0x50, 0x4F, 0x46 };

ASCIIEncoding ascii = new ASCIIEncoding();
String encoded = ascii.GetString(b);

Console.WriteLine(encoded);
