  • Patent number: 7639405
    Abstract: A job, or the copy, is transmitted to a designated destination. A transmission job or a printing job is stored in conjunction with a corresponding execution time in the job storage unit, so that a job can be selected from the job list and the execution time for the selected job can be changed. Further, the jobs stored in the print queue are displayed as a list, and a selected job is moved from the print queue to the job storage unit. In addition, the histories of jobs that were executed are displayed as a list, so that a specific job can be selected and re-executed. When logout is instructed, management data are examined in order to determine whether there is an unprocessed job that was previously instructed by the user. If an unprocessed job is found, the user is notified. If the operator is a manager, a menu is displayed so that all the jobs in the print queue can be deleted. When jobs are deleted, the owners of the individual jobs are notified.

  • Publication number: 20070103724
    Abstract: A job is selected from a job list, and is either copied or is extracted from a job storage unit. The job, or the copy, is transmitted to a designated destination. A transmission job or a printing job is stored in conjunction with a corresponding execution time in the job storage unit, so that a job can be selected from the job list and the execution time for the selected job can be changed. Further, the jobs stored in the print queue are displayed as a list, and a selected job is moved from the print queue to the job storage unit, so that the printing of the job in the print queue can be performed. In addition, the histories of jobs that were executed are displayed as a list, so that a specific job can be selected and re-executed. Furthermore, a process that is performed is managed for the user who instructed the process. When logout is instructed, management data are examined in order to determine whether there is an unprocessed job that was previously instructed by the user.

  • Patent number: 7126717
    Abstract: An attribute of object information to be processed and a corresponding process are designated, and a command to be executed is set. When the process designated for the object information having the designated attribute is performed, the command that is set is executed. Further, a status that is employed as a process execution condition is designated, and a corresponding process that is to be performed while the status corresponds to that of the designated status is stored with that status. Then, when it is determined that the current status is the designated status, the corresponding process is performed, and thus, each time a specific event occurs, a corresponding process can be performed without an instruction having to be issued. Specifically, a trigger for the issuance of a notification is set, and a time period extending from the time the trigger is tripped until the notification is issued is designated.
