  • Publication number: 20040080770
    Abstract: An instruction sheet making section of an instruction sheet editor displays on a GUI icons of services capable of being executed by using a service list sent from a service search server. Further, the instruction sheet making section also displays logic icons of linking processing patterns of the respective services. An instruction sheet making section combines the services provided by one or more service processing sections and makes an instruction sheet, by using service icons and logic icons selected by a user, while referring to and utilizing I/F information sent by the service processing section. Therefore, it is possible to easily combine the services capable of being executed on a network and produce a workflow.

  • Publication number: 20040057076
    Abstract: When a user selects a job order, a job-order analysis section analyzes the job order and supplies required information to a UI generation section and a parameter management section. Data of a scanning operation screen which has been stored beforehand is read out in the UI generation section for a “scan” operation described in the job order, as a type is “scan” indicating a function which has been provided in a multiple function device beforehand. Moreover, the parameter value of “color” on the scanning operation screen is set as “true” in the UI generation section, as the default value of “color” in the job order is “true”. A control panel displays the scanning operation screen generated in the UI generation section.
