Abstract: A communication device receives and stores image data, and searches for information image data in the image data. If found, the information image data is removed, thereby shortening the image so that it can be completely reproduced on one page without compressing or clipping. The information image data may be added to the reproduced image as a watermark, or may be reinserted in a blank space in the image.

Abstract: An information processing apparatus capable of participating in an information processing apparatus having plural information processing apparatuses communicating with one another via a network. The information processing apparatus includes a network control unit capable of being connected to the network; an error monitor configured to monitor if an error exists in the information processing apparatus; and a controller configured to request another information processing apparatus to execute a function which is inexecutable due to an error in the information processing apparatus.

Abstract: An image forming apparatus includes: a web server configured to prompt a user to specify a file as a printing target by an external apparatus and to input information of the user by the external apparatus; an authentication unit configured to authenticate the user based on the input information input by the external apparatus; a transmission/reception unit configured to transmit permission or denial to transmit data from the external apparatus based on an authentication result of the authentication unit; and a print data converter configured to convert the data received from the external apparatus into a printable format.

Abstract: An image processing device is connectable to a host device through a network. In the image processing device, a storage unit stores an identifier capable of distinguishing the image processing device, a communication unit receives data from the host device, a data control unit analyzes the received data, and if the received data include information equivalent to the identifier, a processor executes processing specified by the received data. The host device can learn the identifier by broadcasting a query on the network, then place the identifier in a setting request broadcast on the network, and thereby make or modify network address settings in the image processing device from a remote location.

Abstract: An image forming apparatus has a first image forming unit and a second image forming unit that form images by different methods on the same page. The image formed by the second image forming unit is used as an identifying image to distinguish an original document made by the image forming apparatus from copies of the original document. The second image forming unit may, for example, emboss or punch holes in the printing medium. The second image forming unit may accordingly be a serial impact dot matrix printing unit or a stamping unit, while the first printing unit may be, for example, an ink jet printing unit or an electrophotographic printing unit. One of the two image forming units is preferably capable of making copies by printing on multiple-ply forms.
