Try the following code.

Create the a module 'Module1' and use the following code.

Module Module1
    Private Print_Image As Image
    Declare Auto Function BitBlt Lib "GDI32.DLL" ( _
                  ByVal hdcDest As IntPtr, _
                  ByVal nXDest As Integer, _
                  ByVal nYDest As Integer, _
                  ByVal nWidth As Integer, _
                  ByVal nHeight As Integer, _
                  ByVal hdcSrc As IntPtr, _
                  ByVal nXSrc As Integer, _
                  ByVal nYSrc As Integer, _
                  ByVal dwRop As Int32) As Boolean

    Private WithEvents PrintDocument1 As New Printing.PrintDocument()

    Public Sub doPrint(ByVal frm As Form)
        'We make the form look pritty befor its picture  
        Application.DoEvents()
        frm.Refresh()
        Application.DoEvents()
        'Get a Graphics Object from the form 
        Dim FormG As Graphics = frm.CreateGraphics
        'Create a bitmap from that graphics 
        Dim i As New Bitmap(frm.Width, frm.Height, FormG)
        'Create a Graphics object in memory from that bitmap 
        Dim memG As Graphics = Graphics.FromImage(i)
        'get the IntPtr's of the graphics 
        Dim HDC1 As IntPtr = FormG.GetHdc
        Dim HDC2 As IntPtr = memG.GetHdc
        'get the picture 
        BitBlt(HDC2, 0, 0, frm.ClientRectangle.Width, _
        frm.ClientRectangle.Height, HDC1, 0, 0, 13369376)
        'Clone the bitmap so we can dispose this one 
        Print_Image = i.Clone()
        'Clean Up 
        FormG.ReleaseHdc(HDC1)
        memG.ReleaseHdc(HDC2)
        FormG.Dispose()
        memG.Dispose()
        i.Dispose()
        'Show the PrintDialog 
        Dim PrintDialog1 As PrintDialog = New PrintDialog()

        PrintDialog1.Document = PrintDocument1
        Dim r As DialogResult = PrintDialog1.ShowDialog
        If r = DialogResult.OK Then
            'Print the document 
            PrintDocument1.Print()
        End If
    End Sub


    Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
        Dim formGraphics As Graphics = e.Graphics
        e.Graphics.DrawImage(Print_Image, New System.Drawing.PointF(0, 0))
        e.HasMorePages = False
    End Sub

End Module

Create a form in VB.NET and use the following code.

Public Class Form5
    Inherits System.Windows.Forms.Form

    Public Sub New()
        MyBase.New()

        'This call is required by the Windows Form Designer.
        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub
