The Chr (27) and other codes that you see are printer specific codes. Here is the full list of character codes for Epson:

It may depend on the exact model but there are some EPSON printer codes here for the LX 800:

Ok, now I just write it to a text document instead of writing directly to printer using the code
"TextWriter sw = new System.IO.StreamWriter("C:\\TempBill.txt");"
and print it using a batch file having code
type C:\TempBill.txt > \\system2\EpsonLx-

Ok its printing correctly and both in bold and normal form
the out put is just like this 'Printer is BoldPrinter is BoldPrinter is NormaPrinter is Normal'

Thanks to you ,

and if any one of you know the codes to change font size and style...etc just like the code Chr(27) & "E" Please tell me

Well, it seems that this requires a lot of unmanaged code functionality...please read this link for understanding this better:

Thanks to both of you for the response,

Yes Mamta M, as you are said the code aimed to print in dot matrix printer which is connected to a networked system (system2)

When I write the code you are provided in the line
"StreamWriter sw = new StreamWriter(@"\\system2\EpsonLX-");"

The following error shows,

"FileStream was asked to open a device that was not a file. For support for devices like 'com1:' or 'lpt1:', call CreateFile, then use the FileStream constructors that take an OS handle as an IntPtr."

Please tell me what to do now.

In case, you haven't realized it already, in order to use Mamta's code, you have to:

1. Add a reference to Microsoft.VisualBasic.dll to your project.

2. Add this 'using' directive at the top of the C# source code file:

using Strings = Microsoft.VisualBasic.Strings;

You can also do it in pure C# code:

StreamWriter sw = new StreamWriter(@"\\system2\EpsonLX-");

sw.Write((char)27 + "@");
sw.Write((char)27 + "A" + (char)11);
sw.Write((char)27 + "E");
sw.Write("Printer is Bold");
sw.Write("Printer is Bold");
sw.Write((char)27 + "F");
sw.Write("Printer is Normal");
sw.Write("Printer is Normal");
sw.Close();

I could roughly create this from the given code:

       StreamWriter sw = new StreamWriter(@"\\system2\EpsonLX-");

       sw.Write(Strings.Chr(27) + "@");
       sw.Write(Strings.Chr(27) + "A" + Strings.Chr(11));
       sw.Write(Strings.Chr(27) + "E");
       sw.Write("Printer is Bold");
       sw.Write("Printer is Bold");
       sw.Write(Strings.Chr(27) + "F");
       sw.Write("Printer is Normal");
       sw.Write("Printer is Normal");
       sw.Close();

But whether it works or not will have to be tested by you because I dont have that kind of a printer. Your code is aimed at a dot matrix printer I think.
