Printing form with commondialog in landscape, NOT portrait

I am trying to print a form, but do it in landscape. i have the following code...

VB Code:

Private Sub PRINTButton_Click()
10        DELETESUBButton.Visible = False
20        ADDSUBButton.Visible = False
30        DONEButton.Visible = False
40        DESIGNPropBlockButton.Visible = False
50        DESIGNSwithButton.Visible = False
60        BACKButton.Visible = False
70        PRINTButton.Visible = False
 
          Dim bCancel As Boolean
          Dim nCopy As Integer
80        On Error GoTo ErrorHandler
90        bCancel = False
100       CommonDialog1.FLAGS = cdlPDHidePrintToFile Or _
                                cdlPDNoSelection Or _
                                cdlPDNoPageNums Or _
                                cdlPDCollate
110       CommonDialog1.CancelError = True
120       CommonDialog1.PrinterDefault = True
130       CommonDialog1.Copies = 1
140       CommonDialog1.ShowPrinter
150       If bcancel = False Then
160         For nCopy = 1 To CommonDialog1.Copies
170             frmPowerSystemDesign.PrintForm
180         Next nCopy
190       End If
    
200       DoEvents
    
210       DELETESUBButton.Visible = True
220       ADDSUBButton.Visible = True
230       DONEButton.Visible = True
240       DESIGNPropBlockButton.Visible = True
250       DESIGNSwithButton.Visible = True
260       PRINTButton.Visible = True
270       BACKButton.Visible = True
 
ErrorHandler:
280       If Err.Number = cdlCancel Then
290            bcancel = True
300            Resume Next
310       End If
 
End Sub

It brings up the printer selection, but when you select landscape, it prints in portrait. does anyone know what is wrong....

thanks,
