Abstract: A controller for controlling a display of list information of one or more jobs executed in one or more apparatuses on a display unit is disclosed, wherein with respect to a specified one of display items of the list information of the jobs, the display items each having one or more classifications and having one or more attribute items determined independently for each of the classifications, a selection field for selecting one of the classifications is displayed; and the area of the specified one of the display items is expanded in accordance with the one of the classifications selected in the selection field, and the attribute items corresponding to the selected one of the classifications are displayed in the expanded area with respect to one or more of the jobs related to the selected one of the classifications.

Abstract: A disclosed image formation management system includes image forming apparatuses and a local management apparatus connected via a network to the image forming apparatuses. Each of the image forming apparatuses includes a user information storing unit storing user information of users, a management information storing unit storing a current number of image formation pages and a maximum number of image formation pages of each of the users, and an image formation control unit configured to authenticate the users based on the user information and to limit image formation by each of the authenticated users based on the current number of image formation pages and the maximum number of image formation pages. The local management apparatus is configured to manage the user information and the maximum numbers of image formation pages of the users of the image forming apparatuses.

Abstract: A log information management that includes a communication part configured to communicate with a log information generation device configured to generate log information about a job via a network, and a receiving part configured to receive the log information, to which job creation time information indicating a time when the job is created and log send time information indicating a time when the log information is sent are added, sent from the log information generation device based on a protocol using a tagged structured language via the communication part. The receiving part corrects the time when the job is created based on the difference between the time when the log information is sent, which is indicated by the log send time information added to the log information, and the time when the log information is received based on the protocol using the tagged structured language.

Abstract: A printing system includes a network, a plurality of printers and client devices, each connected with the network. Each of the client devices generates printing data and header information for printing data, according to a user instruction. The header information includes a user ID, a printer ID, and a printing condition. A print restriction server registers, for each user ID, print restriction information including a printer ID, printing functions of the printer usable by the user, and issues and transmits to the client device and in response to the header information, a ticket, when each of the printing functions specified by the printing condition is included in the print restriction information. Each client device generates a printing request. Each printer executes, under specific conditions, a printing operation to print the printing data.
