That will run when you click the Print button on the toolbar (in Word
2003 or earlier; in Word 2007 you would have to use the Customize

If you want the Print dialog to appear when you press Ctrl+P and have
the "Current page" option button selected, then use this macro
(instead of or in addition to the first one):
Sub FilePrint()
With Dialogs(wdDialogFilePrint)
.Range = wdPrintCurrentPage
.Show
End With
End Sub
