Prevent Zero Dollar Check from Printing

Summary

We wish to prevent zero dollar checks from printing in order to save print stock

We have a fairly large number of credits we have to process (they are coming in from an External System) which combined with the Oracle AP Invoices would result in zero dollar checks being printed. In order to get rid of the credits we need process the payment, but we don't want to print the checks. Would anyone know how we could do this? Our bank account is setup to all zero dollar payments - we had to do this to use the credits.
