Print report directly, without print dialogue box and report viewer

Hi,
I need to print my reports directly to printer:

1) Without showing print dialogue box
2) Without showing the Reportviewer

I was suggested the following code:

Dim printerSettings As New PrinterSettings()
        Dim printDialog As New PrintDialog()
        printDialog.PrinterSettings = printerSettings
        printDialog.AllowPrintToFile = False
        printDialog.AllowSomePages = True
        printDialog.UseEXDialog = True
        Dim result As DialogResult = printDialog.ShowDialog()

        If result = DialogResult.Cancel Then
            Return
        End If

        Me.rptSalesReport.PrintOptions.PrinterName = printerSettings.PrinterName
        Me.rptSalesReport.PrintToPrinter(printerSettings.Copies, False, 0, 0)

But I am receiving error on the last two lines, where I put the name of my reports,
rptSalesReport. It says:

rptSalesReport is not defined.

While the rptSalesReport is there in my project and I can view it through report viewer.
Please advise.
Thanks
