Abstract: A device may receive, from a set of elements of a set of network devices, information associated with a set of parameters. The device may determine an event based on the set of parameters. The device may determine a rule set based on the event. The device may determine other events that are associated with the event based on the rule set. The device may determine statuses of the other events based on the information associated with the set of parameters. The device may evaluate a rule, of the rule set, based on the event and the statuses of the other events. The device may determine an action to be performed based on evaluating the rule. The device may cause the action to be performed in association with the element of the set of elements.

Abstract: A method is described comprising associating (104) a first identifier with a print job, holding (106) the print job without it printing, and releasing (108) the print job to print when a device is activated to provide a second identifier and the second identifier is related to the first identifier. An apparatus is also described comprising a receiver (18) of a print job which is associated with a first identifier, and an interface to a device (22) which provides a second identifier. The receiver (18) is configured to initially hold the print job without it printing, and the receiver (18) is configured to cause the print job to be printed by a printer (20) when the device (22) is connected to the interface, the second identifier is obtained from the device (22) and the second identifier is related to the first identifier.
