Abstract: An image forming device is disclosed which includes an interrupt job display unit, an interrupt job selection unit, and an interrupt control unit. The interrupt job display unit will display details of an image forming job (an interrupt job) in an interrupt job window that is requested while another image forming job is being performed. The interrupt job selection unit allows an operator to permit or reject the execution of the interrupt job that is displayed on the interrupt job window. The interrupt control unit will execute the interrupt job if the operator permits the execution of the interrupt job. The interrupt job display unit displays interrupt job windows corresponding to a plurality of interrupt jobs that are requested while another image forming job is being performed. The interrupt job windows are displayed so as to overlap and be individually identifiable by an operator.

Abstract: An element management system which allows a client to monitor and control elements on a network through element management servers includes a unit configured to manage a transfer state separately for each element when management information regarding an element accommodated in a first element management server is to be transferred to a second element management server, and a unit configured to cause the management information at the second element management server to reflect a differential between the management information at the first element management server and the management information at the second element management server upon creation of the differential that is created by the client upon controlling an element for which the transfer state indicates uncompleted transfer, wherein an accommodated element is transferred in real time between the first and second element management servers without suspending monitor and control performed by the first and second element management servers.

Abstract: According to a first network facsimile machine 11 among network facsimile machines of the present invention, for example, a main control section 17 makes a domain determination whether an electronic mail having been transmitted is from a domain of an important other party by referring to a domain management table in a domain registration section 35 as appropriate. When a determination that the electronic mail having been transmitted is from a domain of an important other party is made, as a result of the domain determination, the main control section 17 serves so as to raise a priority level of a job associated with the electronic mail. Therefore, a job related to the domain registered as the important other party is processed with priority through properly managing a priority level of a job on a network. As a result, a latency time until a job related to electronic mail having been transmitted from an important other party is started can be reduced as short as possible.
