Print from an MDI-form

How is it possible printing from the menu in an MDI-form?

I have used

Private Sub mnuPrint_Click()
Form1.PrintForm
End Sub

but this does not include the MDI-form.
And there isn't a function named MDIForm1.PrintForm.

I am looking forward for your reply.
Best regards

Try the following :

MDIForm1.ActiveForm.PrintForm
