Web printing crystal report hangs on report.PrintOptions.PrinterName

Question

Hello,
I have a report web page that displays a crystal report.  I have added a modal popup to allow them to select their printers.  When I go to print the report is hangs on the line of rpt.PrintOptions.PrinterName = li.Text.  The printer names are added to the list box using a Java applet.
Here is the Sub it is running.
    Public Sub PrintReports()
        rpt = CType(Session("rpt"), ReportDocument)
        For Each li As ListItem In Me.lbPrinters.Items
            If li.Selected AndAlso li.Text <> "" Then
                rpt.PrintOptions.PrinterName = li.Text
                rpt.PrintOptions.PrinterDuplex = CType(Me.cboDuplex.SelectedItem.Value, CrystalDecisions.Shared.PrinterDuplex)
                rpt.PrintToPrinter(CInt(Me.txtNumOfCopies.Text), True, CInt(Me.txtPageStartRange.Text), CInt(Me.txtPageRangeEnd.Text))
            End If
        Next
        Me.mpePrint.Hide()
    End Sub
Any help would be greatly appreciated.
Thanks,
Patrick

Sounds like you're trying to implement server side printing in your app. Which is fine, except the CR ActiveX print is client side printing. Just in case you're interested, the way to enable activeX print is to go to the property of the CR viewer and find "PrintMode". It will more than likely be defaulted to PDF. Change that to ActiveX.
Now, back to the issue. This may still be a matter of permissions - essentially what Adam was after. Probably the easiest way to determine that is to use the [Process Monitor|http://technet.microsoft.com/en-ca/sysinternals/bb896645.aspx] utility. Once you have the log, search it for "Access Denied" messages.
