Silverlight Printing string value - string

Question

Currently i am working with silverlight 4, we are converting windows based application into silverlight. In windows based application to print string is easy using COM, but client side application like Silverlight is it possible to print string value ?
I have to convert this to Silverlight :
Dim PD As New PrintDialog
PD.UseEXDialog = True
PD.PrinterSettings = New System.Drawing.Printing.PrinterSettings
If (Windows.Forms.DialogResult.OK = PD.ShowDialog()) Then
ZPLZebra.RawPrinterHelper.SendStringToPrinter(PD.PrinterSettings.PrinterName, *******.ToString())
End If
Edit 1:
public static bool SendBytesToPrinter(string szPrinterName, IntPtr pBytes, int dwCount)
{
IntPtr hPrinter = new IntPtr(0);
DOCINFOA di = new DOCINFOA();
bool flag = false;
di.pDocName = "My C#.NET RAW Document";
di.pDataType = "RAW";
if (OpenPrinter(szPrinterName, out hPrinter, 0L))
{
if (StartDocPrinter(hPrinter, 1, di))
{
if (StartPagePrinter(hPrinter))
{
int dwWritten = 0;
flag = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);
EndPagePrinter(hPrinter);
}
EndDocPrinter(hPrinter);
}
ClosePrinter(hPrinter);
}
if (!flag)
{
Marshal.GetLastWin32Error();
}
return flag;
}
public static bool SendStringToPrinter(string szPrinterName, string szString)
{
int length = szString.Length;
IntPtr pBytes = Marshal.StringToCoTaskMemAnsi(szString);
SendBytesToPrinter(szPrinterName, pBytes, length);
Marshal.FreeCoTaskMem(pBytes);
return true;
}
Ref:(this is my exact requirement)- Printing "raw text" (ZPL) from Web

Answer 1

You can use PrintDocument.Print method and in PageVisual send a grid with text block ?
Sample code in C#
/// <summary>
/// Text to print.
/// </summary>
private string _textToPrint;
/// <summary>
/// Method that print text.
/// </summary>
/// <param name="textToPrint">Text to print</param>
/// <param name="documentName">Optional document name.</param>
public void SendStringToPrinter(string textToPrint, string documentName = "My Document")
{
// Set print content in private property
_textToPrint = textToPrint;
// Create a new print dialog
PrintDocument pd = new PrintDocument();
// Catch print event
pd.PrintPage += onPrintPage;
// Start print request
pd.Print(documentName);
}
/// <summary>
/// Called during printing.
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void onPrintPage(object sender, PrintPageEventArgs e)
{
// Create a UI element (simple grid with textblock inside).
var grid = new Grid();
grid.Children.Add(new TextBlock()
{
Text = _textToPrint
});
// Add the grid to print visual.
e.PageVisual = grid;
}
You can call :
SendStringToPrinter(*******.ToString());
