Printing in VB5

Hi,
I am trying to print a form out, and can´t get it centralised on the printed page - any suggestions please on how I can do this using VB5? Also, is there anyway of making buttons invisible when printing, except by making the visible property = false?

Cheers,
Sparky

About the buttons:

Code:

---

Private Sub hideAllButtons(frmIn as form)
  Dim c as control
  For each c in frmIn.controls
    If TypeOf c Is Button then c.visible = False
  Next
End Sub
