How to Print the Data Content on a Web Page without asking Print dialog window...

Hi Friend..

Thanks for your valueable answer, i am also think like that as you telling,its a security purpose.... fine !...

but, i think you seen some applications like Railway Reservation, Restorent, etc while printing the tickets or bills,they click the print button it is automatically printed..i thought they write the own code in theire project for print button,thats why i am asking, i want such type of answer...in my project also same thing, my client wants asking such type only...what to do ? there is no another way ? except printer setting or window.print(); method ?

i have a one VB code i found in Google, its working fine, but it will be printing blank page & in that code they are passing some parameters, really i did't get that code... so see that code, if you got the answer tell me how to use that ok..

Here is that code:

There is a one Gridview contains some data like MRN, Name,Address etc and below Gridview i am taking one Commnd Button is there called Print ..so when i click the Print Button I want to print Gridview contents that’s all..when i click the Print Button records will be printing directly

-------------------Button----------------

Private Sub PrintButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintToolStripMenuItem.Click

    

     Dim strPrinterName As String

     Call SetDefaultSystemPrinter(strPrinterName)

 

End Sub

--------------------Function -----------------

 

Public Function SetDefaultSystemPrinter(ByVal strPrinterName As String) As Boolean

        ' Imports System.Drawing.Printing

        ' Example: SetDefaultSystemPrinter("Lexmark T620") - local printer

        ' Example: SetDefaultSystemPrinter("\\Server01\Lexmark T522") - network printer

        Dim strOldPrinter As String

        Dim WshNetwork As Object

        Dim pd As New PrintDocument

        'Dim x As String

        ' Set the default system printer

        Try

           'strPrinterName = InputBox("Printer name", "Set the default system printer", strPrinterName)

            strPrinterName = "\\192.168.1.100\FIRST FLOOR PRINTER"  //my system printer path 

            strOldPrinter = pd.PrinterSettings.PrinterName '/ Get the system default printer

            WshNetwork = CreateObject("WScript.Network")

            WshNetwork.SetDefaultPrinter(strPrinterName)

            pd.PrinterSettings.PrinterName = strPrinterName '/ Specify the printer to use.

            If pd.PrinterSettings.IsValid Then '/ Check that the printer exists

                pd.Print() '/ Print a document

                Return True

            Else

                MessageBox.Show("Printer <" & strPrinterName & "> is invalid.")

                WshNetwork.SetDefaultPrinter(strOldPrinter)

                Return False

            End If

        Catch exptd As Exception

            WshNetwork.SetDefaultPrinter(strOldPrinter)

            Return False

        Finally

            WshNetwork = Nothing

            pd.Print()=Nothing

           

        End Try

End Function '/ SetDefaultSystemPrinter

Thank you Sir...
