Customer Invoice Printing - 11i

Dear Oracle Gurus,

Our business has this requirement:

There are overnight scheduled Oracle Invoice Print requests for printing the Customer invoices from a physical printer. But in our UK entity, the printer is in a common location so we need to secure the customer invoices. Is there a way we can but a control on the Oracle Invoice print request such that for UK alone these are not automatically printed off a physical printer until the collection admin authorises to do so?

Thanks
