The present invention is in the field of electrophotographic printers and copiers. Upon receiving a request to access the user account, a determination of whether the user account is in a throttled state may be made. Based on the maximum permitted rates and the burst access thresholds, each source node in the network then controls, at the burst level, the traffic accessing the network and reserves for each admitted burst the burst peak packet rate on a predetermined route, without communicating with other nodes in the network. A final rank corresponding to each of the plurality of digital images is then determined based on the one or more ranks assigned by the one or more crowdworkers to each digital image of the plurality of groups. The control unit 11 also refers to the end pointer for confidential print jobs and moves the confidential print job A to the end of the confidential print jobs.
