Abstract: In a source file for a server, a Web display control division, a CGI script division and a processing program division are separated. The server has a Web server division, a CGI script control division and a processing program division and constitutes an interactive system together with an operation terminal unit in which inputs are made through a Web browser. A display control file describing Web page control information is provided for each Web page to be displayed, and the CGI script control division analyzes the description of the said display control file designated by said Web browser, executes said processing program following the description and outputs the result of the processing from Web server division to said Web browser. The name of processing programs activated for collection of information for the display of a Web page and control of the system and a method for displaying the result of such processing on the Web page are described in a script format in the display control file.

Abstract: A printing apparatus which enables the operator to immediately discriminate a position of a check objective paper from results of printing has a printing mechanism for printing in at least one color on predetermined papers, a control unit for controlling a printing operation of the printing mechanism, and a detecting unit for detecting an opportunity of printing and outputting the check objective paper during the printing operation of the printing mechanism. When the detecting unit detects said opportunity, the control unit controls the printing mechanism to implement a color printing on the check objective paper in order to discriminate the check objective paper from another printed output papers. The printing apparatus is applicable to a printer which is connected to an upper apparatus such as a host computer to print data fed from the upper apparatus.
