Embodiment approach

[0034] Fig. 1 shows a communication system including an image processing device, more specifically a printer, according to a first embodiment of the present invention. The printers 1, 2 are connected to a host device 3 such as a personal computer through a network 4 (usually a LAN), although the first embodiment is not limited to a LAN environment.

[0035] In the system of FIG. 1 , a system administrator or other user at host device 3 may send broadcast messages over network 4 . A broadcast message is a message with an empty destination address, which is received and analyzed by all other devices connected to the network 4 . One type of broadcast that can be sent is a request for information about a connected device.

[0036] In response to such a request, the connected device sends a new identifier (ID), along with its unique Media Access Control (MAC) address and other general information. Based on the received information, the user can send other commands to the specific...

no. 2 approach

[0090] Fig. 18 shows an exemplary communication system including an image processing apparatus, particularly a printer, according to a second embodiment of the present invention. Like the first embodiment, the printers 51 , 52 are connected to the host device 3 via the network 4 . The second embodiment differs from the first embodiment in that the printer has two network cards each as described for the printer 51 . The two network cards 11, 53 are the same as the network card 11 in the first embodiment. In other respects, the printer 15 is also the same as the printer 1 in the first embodiment, and further includes an image forming and printing section 12 , an IEEE 1394 card 13 and a USB card 14 .

[0091] 19 is a block diagram showing key components of the printer 51, including two network cards 11, 53, an image forming and printing unit 12, and a serial number storage unit 15. The printer 52 has the same structure related to these components. For simplicity, the IEEE 1394...

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.

Description

technical field [0001] The present invention relates to an image processing device connectable to a communication network such as a local area network. Background technique [0002] Currently, local area networks interconnecting multiple devices such as personal computers, printers, and other computing and image processing devices generally operate according to the well-known Transmission Control Protocol / Internet Protocol (TCP / IP). In a TCP / IP network, each connected device is identified by an IP address, and the IP address is used as the destination address of data transmission. Thus, before a device can receive unicast data addressed to it, it must be assigned an IP address. [0003] If the device in question is a printer, setting the IP address includes actions performed directly on the printer's control panel, switch settings made on an interface card installed in the printer, or a computer connected to the printer on a one-to-one basis or actions performed on other d...
