What is your question?

if (bSuccess == false)
{
dwError = Marshal.GetLastWin32Error();
}
return bSuccess;
}
public static bool SendFileToPrinter(string szPrinterName, string szFileName)
{
FileStream stream1 = new FileStream(szFileName, FileMode.Open);
BinaryReader reader1 = new BinaryReader(stream1);
byte[] buffer1 = new byte[((int)stream1.Length) + 1];
buffer1 = reader1.ReadBytes((int)stream1.Length);
IntPtr ptr1 = Marshal.AllocCoTaskMem((int)stream1.Length);
Marshal.Copy(buffer1, 0, ptr1, (int)stream1.Length);
bool flag1 = RawPrinterHelper.SendBytesToPrinter(szPrinterName, ptr1, (int)stream1.Length);
Marshal.FreeCoTaskMem(ptr1);
return flag1;
}
public static void SendStringToPrinter(string szPrinterName, string szString)
{
IntPtr pBytes;
Int32 dwCount;
dwCount = szString.Length;
pBytes = Marshal.StringToCoTaskMemUni(szString);
SendBytesToPrinter(szPrinterName, pBytes, dwCount);
Marshal.FreeCoTaskMem(pBytes);
}
}
}

hiThus, according to the changes made ، my new class is As follows :

note : this new class just print ascii characters and i still can not print unicode format . please some one help to change this class for print unicode format . SUCH AS (FARSI) OR (ARABIC) OR (URDO) OR MORE UNICODE ? It is very necessary and important for me ....
