Example apparatus and methods are disclosed for monitoring and controlling networked printing devices. A computing device can capture a printing device identifier of a printing device, where the printing device can be communicatively coupled to at least the computing device via a local network. The computing device can send a request to unlock the printing device. The computing device can receive an indication that the printing device is unlocked. After receiving the indication that the printing device is unlocked, the computing device can send a job request requesting execution of a job on the printing device, where the job request can include identification information associated with the computing device and the printing device identifier. The computing device can send job accounting information related to usage of the printing device related at least to the executed job request.
