Abstract: When a user desires to periodically subscript a certain Web page (to automatically print the Web page), the user makes access to a sign-up page of the desired Web page by using a PC, via a facsimile machine. When the user clicks an “OK” button on the sign-up page, a setting request is transmitted to a Web server through the facsimile machine. In response to the setting request, the Web server sends back a data packet including an HTML document with a comment tag including periodical subscription setting data, as a response to the user. The transmitted periodical subscription setting data is received by the facsimile machine. When receiving the response, the facsimile machine determines whether a receiver's IP address and port number included in the data packet have been registered in the facsimile machine.

Piping 1 having a fluid-mixing region M includes a reducer 5 including an end portion 5e disposed substantially on a central axis of a main pipe 2.

Abstract: A facsimile device downloads data from a web server if a URL of the web server is not listed in an access prohibited database. If it is determined that the downloaded data is of the type for which image formation is prohibited, then a printing function is set to OFF. If the printing function is ON, then a display unit displays an outline of the downloaded data, enabling a user to determine whether or not the downloaded data should be printing out. If the user input a print instruction, then the downloaded data is printed out. On the other hand, if the user input a cancel instruction, then the downloaded data is not printed out.
