Abstract: The present invention is to provide an optical recording medium which is capable of performing good recording and reproducing by using a laser having a wavelength of 300 to 900 nm, a novel azo metal chelate compound, and a novel azo compound. Furthermore, the present invention is to provide an optical recording medium having an azo metal chelate compound in a recording layer.

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.

Abstract: Corresponding security policies are applied to a discovery protocol as a protocol used in the discovery phase and a control protocol as a protocol used in the control phase of a device control protocol when communications are made.
