Hey,.. well i figured it out 
The report will be printed from a form command button
I created 2 Unbound Hidden text boxes on the form.
Code:
txtAccounts = Default Value - "Accounts"
TxtStores = Default Value - "Stores"
I then created a Unbound text Box accross the report header,.. = txtWatermark. And set the forecolor to a pale red = -2147483630
And Used the following code behind the Onclick Event of the form command button
Code:
Dim stDocName As String
stDocName = " ReportName "
DoCmd.OpenReport stDocName, acPreview
DoCmd.PrintOut
Reports.ReportName.txtWatermark = Forms!switchboard! txtAccounts
DoCmd.PrintOut
Reports. ReportName.txtWatermark = Forms!switchboard! txtStores
DoCmd.PrintOut
DoCmd.Close
The Result Being,
1st printout = No Watermark
2nd printout = Accounts Watermark
3rd printout = Stores Watermark
