METHOD AND APPARATUS FOR SECURING PERIPHERAL DEVICES

A printing machine 1 comprises a processor (2a) and a memory (2b, 2c) storing computer readable instructions. The computer readable instructions are arranged to cause the processor (2a) to generate access request data for processing by an access control server (3), receive access response data responsive to the access request data, process the access response data to determine a first print type and a first print quantity indicated by the access response data, and update, responsive to processing the access response data, an access status in the memory to indicate a second print quantity for the first print type.
