Disable Print If Specific Cells Are Empty

I am currently trying to keep the print feature disabled in excel untill any of three specific cells are filled out. So that any of the following possibilities would work:

A2 H2 P2
[x] [ ] [ ]
[ ] [x] [ ]
[ ] [ ] [x]
[x] [x] [ ]
[ ] [x] [x]
[x] [x] [x]

This is what I've got so far.

Private Sub Workbook_BeforePrint(Cancel As Boolean)
If IsEmpty(Range("A2,H2,P2")) Then
Cancel = True
End If
End Sub

This code works for A2 but I can't get it to work for H2 or P2. i.e. print will be enabled if A2 has content and disabled if all three cells are blank, but if A2 is empty and H2 has content print will remain disabled.
