Hi Emanuele !
Sorry for the late answer. The sample that I posted was for a Datamax printer. So in Eltron/Zebra,
it should go something like this:
char sn = '"';
MemoryStream memStrm = new MemoryStream();
StreamWriter sw = new StreamWriter(memStrm);
sw.WriteLine("\n"); // new line to start command structure
sw.WriteLine("N"); // clear image memory from last printed label
sw.WriteLine("X0,0,4,752,584"); // draw a box
sw.WriteLine("LO0,144,752,4"); // draw a line
sw.WriteLine("A40,400,1,1,1,1,N," + sn + "Made in Norway" + sn);
sw.WriteLine("B280,440,0,1,2,3,96,B," + sn + "S 000001" + sn); // write a barcode
sw.Flush();
sw.WriteLine("P1"); // print 1 label
sw.WriteLine(""); // empty line
sw.Flush();
memStrm.Position = 0;
LabelPrint.SendDocToPrinter(pd.PrinterSettings.Pri nterName,memStrm);
sw.Close();
The sample above is simple, but it's all I had time to do now. Not that you should add a method to
the article file called SendDocToPrinter. I've posted the code below:
<code for the SendDocToPrinter function>
public static bool SendDocToPrinter( string szPrinterName, MemoryStream ms)
{
// Open the file.
//FileStream fs = new FileStream(szFileName, FileMode.Open);
// Create a BinaryReader on the file.
BinaryReader br = new BinaryReader(ms);
// Dim an array of bytes big enough to hold the file's contents.
Byte []bytes = new Byte[ms.Length];
bool bSuccess = false;
// Your unmanaged pointer.
IntPtr pUnmanagedBytes = new IntPtr(0);
int nLength;
nLength = Convert.ToInt32(ms.Length);
// Read the contents of the file into the array.
bytes = br.ReadBytes( nLength );
// Allocate some unmanaged memory for those bytes.
pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);
// Copy the managed byte array into the unmanaged array.
Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);
// Send the unmanaged bytes to the printer.
bSuccess = SendBytesToPrinter(szPrinterName, pUnmanagedBytes, nLength);
// Free the unmanaged memory that you allocated earlier.
Marshal.FreeCoTaskMem(pUnmanagedBytes);
return bSuccess;
}
</code for the SendDocToPrinter function>
I'm trying to print on an Eltron TLP2247. Using the example that you
suggest, nothing appen on the printer.
How can i sent EPL command do the printer?
Thnks
