Stop Update Message When Printing From Macro

I have a macro which auto prints a series of workbooks and it works very well - except (there is always an except right?) some of the workbooks brink up a dialog box saying "this workbook contains links to other data sources" Update, Don't Update or Help"

how to prevent this box from appearing and interrupting the print flow? I want to be able to run this macro and wallk away while it merrily does its printing job - not sit at the monitor hitting No No No over and over (yes i do NOT want to update the workbook)

Public Sub Auto_Open()
Dim sCurFile As String
Dim sPath As String
Dim mpath As String

mpath = InputBox("Enter the month and year, i.e. 0207 for Feb 2007", "print")

fpath = InputBox("Enter day of the month to print (no leading 0's)?", "print")
