Abstract

PROBLEM TO BE SOLVED: To confirm and communicate the generation of any failure due to the change of network connection information to a user. SOLUTION: At the time of receiving the change of setting by an operator from a control panel (1-70), an operation display controlling part (1-23> judges whether or not a DHCP(dynamic host configuration protocol) should be validly set or invalidly set. When it is judged that the DHCP setting should be validly set, the setting information of a picture processor (1-20) stored in a setting information storing part (1-25) is extracted, and information whose DHCP is invalid and the extracted setting information of the picture processor (1-20) is inputted to a setting information comparing and deciding part (1-22), and whether or not all I/F can operate at the time of validating the DHCP is judged. When it is decided that any I/F can not operate at the time of validating the DHCP, the operation display controlling part (1-23) displays the presence of the I/F which can not operate at the time of validating the DHCP at the control panel (1-70).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for executing a print job sent via a network,
For example, the present invention relates to an image processing apparatus having a function of developing image data into drawing data while receiving or storing image data transmitted from a communication terminal connected to a network, or storing and outputting the image data. The present invention relates to an image processing apparatus having a function of activating a network after automatically obtaining information necessary for setting a network from another device on the network at the time of activation.

2. Description of the Related Art In recent years, networks have become widespread, and communication devices connected to the networks have increased in offices. By connecting to a network, a host and a printer can be installed at a remote place, or one printer can be shared by a plurality of hosts, thereby improving convenience. In recent years, the Internet and intranet have become widespread. By connecting via the Internet, it is possible to communicate with Internet-connected terminals all over the world, and information can be easily exchanged using the Internet mail function. In addition, a database is used in an intranet environment in a company, and necessary information can be obtained with a simple operation.

[0003] The Internet and intranets use TCP / IP (Transmis- sion) as a network protocol.
Sion Control Protocol / Int
(Ethernet Protocol), and all connected terminals are identified by IP addresses. In addition, the printer device is also identified by the IP address,
Lpd (RFC1
179) (LinePrinter Diamond P
rotocol, Request ForCommen
t) and the like.

On the other hand, with the spread of the Internet,
The size of the network has also increased. With the expansion of the network, the management of the network has also required a lot of man-hours and efforts.

[0005] In particular, the number of man-hours required for managing the address of each terminal connected to the network increases according to the scale of the network.

In order to make network management more efficient,
In particular, a DHCP (Dynamic Host Config) method for centrally managing and automatically distributing address information and the like in order to efficiently manage IP addresses is known.
(Protocol.ration Protocol). This management method is defined in RFC1514. The use of DHCP eliminates the need for an address manager to set an address for each terminal, and has the advantage that management becomes easier.

[0007] A terminal on a network is identified by address information such as an IP address. A management method for associating a terminal name assigned to a terminal with a terminal address has been proposed as a DNS (Domain Name System). . This management method is defined in RFC1035. When DNS is used, the user of each terminal can identify a target terminal by a terminal name, and thus has an advantage of being easy to use.

Although it is convenient to use both DHCP and DNS in a network system, there is an advantage that the number of management steps can be reduced. However, DHCP is a method for dynamically managing addresses, and DNS is a fixed host name and terminal device. In order to use both types of management in a mixed manner, it is necessary to manage the relationship between DNS and DHCP, and there is a problem that a new management man-hour is required.

[0009] Japanese Patent Application Laid-Open No. 9-282259 discloses a DH using a name and address information common to all networks.
A network system using both CP and DNS has been proposed. According to this prior art, since the address can be dynamically managed and the name service by DNS can be used, there is an advantage that the usability of the network is good. Also, no matter where the terminal is installed on the network system, you can connect to the terminal that moved with the same name,
Further, since the address can be managed only by the management by the DHCP, there is an advantage that the man-hour for the administrator due to the movement of the terminal can be reduced.

[0010]

The above-mentioned prior art is effective when the entire network is under one management system.
This cannot be applied to a network in which a group using only P or a group using only DNS exists and is managed using individually divided address spaces.

[0011] Further, even in a network system in which the entire system is managed, some applications are not suitable for DHCP, and some applications must be individually managed depending on applications used by terminals. An application that is not suitable for DHCP is, for example, an application that generates a license or an access key based on an IP address. These application terminals are set to be activated without operating DHCP. In network terminals, host devices such as personal computers and workstations have limited users and administrators who use the host devices. Therefore, the settings were not accidentally changed, but were not changed by printers and other devices. In a terminal used by a specific large number of users, particularly in a printer device capable of printing by a plurality of applications, application settings are made for each individual application user, and contradictory settings may be made depending on applications. Here, the application whose setting is inconsistent is, for example, an application that operates even in a DHCP environment and an application that generates key information from the address and operates based on the key information. An application that operates based on key information generated from an address generally operates on the assumption that the key information does not change. Therefore, it does not operate normally in an environment where addresses are dynamically changed such as DHCP. .

Therefore, in a terminal device such as a printer,
Since the user can freely change the operation, even if the user who changes the operation does not intend, changes that affect other applications are likely to be made, and the printer terminal often does not operate properly. Had occurred.

[0013] An object of the present invention is to improve the above-mentioned problems in the prior art, even if a function to be used by a plurality of applications at the same time under different network environments or setting conditions is provided. An object of the present invention is to provide an image processing apparatus that prevents settings that cause inconsistency.

[0014]

According to a first aspect of the present invention, in order to achieve the above object, an image processing apparatus includes: obtaining connection information for obtaining network connection information from an external device via a network. Means; automatic setting means for automatically setting a network from the connection information obtained by the connection information obtaining means;

In this configuration, when an attempt is made to change to a setting that is inconsistent with the operation setting of the network that has already been set, the operator is notified that the setting is inconsistent and whether or not to enable the setting change. It can be carried out.

According to a second aspect of the present invention, the image processing apparatus includes: connection information obtaining means for obtaining network connection information from an external device via a network; connection obtained by the connection information obtaining means. Automatic setting means for automatically setting a network from information; setting method selecting means for selecting whether or not the network setting is to be performed by the automatic setting means; and a plurality of inputs set in the image processing apparatus main body. Setting condition detecting means for detecting the setting condition of the means; if the setting method selecting means sets the automatic setting selecting means, whether the setting of the input means detected by the setting condition detecting means of the input means is appropriate Input setting discriminating means for judging the condition; and means for changing the setting condition of the input means in accordance with the judgment result of the input setting judging means. It has to so that.

In this configuration, if a setting that is inconsistent with the already set network operation setting is made,
Operation settings that conflict with the settings can be canceled or changed.

Further, in this configuration, when the setting conditions of the input means are changed in accordance with the result of the judgment by the input setting judging means, means for notifying of the change may be further provided. In this case, if an attempt is made to change to a setting that is inconsistent with the operation setting of the network that has already been set, a notification is made as to whether or not to enable the setting change.
When the changed setting is made valid after the notification, the terminal on the network can be notified of the change.

According to a third aspect of the present invention, the image processing apparatus includes: connection information obtaining means for obtaining network connection information from an external device via a network; connection obtained by the connection information obtaining means; Means for setting a network from the information; means for detecting a validity period of the information from the connection information obtained by the connection information obtaining means; and setting conditions of a plurality of input means set in the image processing apparatus main body. Means for detecting; reconnection information obtaining means for obtaining reconnection information of a network to be reset when the detected validity period has elapsed; reconnection information obtained for the resetting; Connection information discriminating means for discriminating whether or not the same connection information has been set; and determining the detected setting condition in accordance with the discrimination result of the connection information discriminating means. Further changing means and; by said changing means, be provided with a means for notifying the setting condition of the modified input means.

In this configuration, when the validity period of the connection information used for the operation setting of the network has expired, the reconnection information can be automatically obtained, and the setting according to the obtained reconnection information can be performed. .

It is needless to say that the present invention can be realized at least in part as a computer program product. In the above description, confirmation or notification is performed when the connection setting is changed. However, when a predetermined input unit (I / F) that does not operate under DHCP is already set, a change to enable DHCP is performed. It can be discarded. Further, the I / F set to be not so important may not be notified at all even if it does not operate when DHCP is enabled. That is, the notification may be selectively generated.

Further, the request for the reset information is not made once. For example, even if the reset information is periodically requested within a certain period as a period from one third to seven eighths of the validity period, the effect is not obtained. does not change. Furthermore, when requesting reset information, even if a method of requesting the same address is used based on address information that has already been set,
The effect remains the same.

[0057]

As described above, according to the present invention,
The following effects are obtained.

First, when an attempt is made to change the setting to a setting inconsistent with the operation setting of the network, the operator is notified that the setting is inconsistent and whether or not the setting change is valid. Therefore, in a printer having a means for connecting to a plurality of network applications, there is an effect that it is possible to prevent an erroneous operation by an operator or a change to a setting in which another user cannot use the printer unintentionally.

When a setting inconsistent with the already set operation setting of the network is performed, the operation setting inconsistent with the setting can be canceled or changed. Therefore, a means for connecting to a plurality of network applications is provided. In a printer, the effect of preventing an operator from erroneously operating or changing the setting so that another user cannot use the printer unintentionally, and thereby transmitting data with a wrong setting on the network can be prevented. is there.

When a change is made to a setting that is inconsistent with the operation setting of the network that has already been set, a notification is made as to whether the setting change is to be made valid. After the notification, the changed setting is made valid. In this case, it is possible to notify the terminal on the network that the change has been made, so even if the operator makes an erroneous operation or unintentionally changes the setting so that other users cannot use the printer, it will be affected The user of the application on the network can reduce the trouble of investigating a state where the application cannot be used.

Further, when the validity period of the connection information used for the operation setting of the network expires, the reconnection information can be automatically obtained and the setting according to the obtained reconnection information can be performed. It is possible to prevent the transmission of the data having the above-mentioned settings, and to reduce the trouble of the user of the application on the network to investigate the state in which the application cannot be used by changing the setting.
