A printer credit management method is disclosed, the method includes receiving a code at a printer. From the code, a printer identifier and a credit value are discerned. It is determined if the printer identifier corresponds to a unique identifier assigned to the printer. Only upon a positive determination, a credit balance maintained by the printer is updated to include the credit value.
