在横向模式下打印vb.net

我有我的数据集的代码来填充datagridview.

Private Sub print_Load(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles MyBase.Load

    Dim query As String = "SELECT * FROM TBLusers"
    Dim DA As New SqlDataAdapter(query,CN)
    Dim DS As New DataSet
    CN.Open()

    DA.Fill(DS,"Users")
    CN.Close()
    DataGridView1.DataSource = DS.Tables("Users")
    'DataGridView1.DataMember = "Users"


End Sub

这是我猜的打印功能？我是从教程中得到的.

Private Sub printDocument1_PrintPage(ByVal sender As Object,ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

    Dim dataGridViewImage As New Bitmap(Me.DataGridView1.Width,Me.DataGridView1.Height)
    DataGridView1.DrawToBitmap(dataGridViewImage,New Rectangle(0,Me.DataGridView1.Width,Me.DataGridView1.Height))
    e.Graphics.DrawImage(dataGridViewImage,0)
End Sub

这是打印预览.

Private Sub Button2_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles Button2.Click

    PrintPreviewDialog2.Document = PrintDocument1
    PrintPreviewDialog2.PrintPreviewControl.Zoom = 1
    PrintPreviewDialog2.ShowDialog()
End Sub

和印刷品……

Private Sub Button1_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles Button1.Click

    PrintDocument1.Print()
End Sub

我试过了
PrintDocument1.PrinterSettings.DefaultPageSettings.Landscape = True

但似乎没有用？
