Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication processing system, and more particularly to a scanner printer server system in which an integrated scanner printer is connected to a network.

[0002]

2. Description of the Related Art In recent years, no attempt has been made to connect an integral type scanner to a network, but it has only been used as a copy machine by itself.

However, there are printer servers that share a printer by connecting the printer to the printer server on the network.

Usually, such a printer server is installed near a computer and is used by a plurality of users who use the computer in a state where the terminal and the computer are connected by RS232C or the like. Therefore, it is necessary for the user to work in a place relatively close to the computer.

Also, when trying to print the calculation result, the printer server was installed near the user. Therefore, I was able to print the calculation result on the printer server and get the output immediately. Therefore, even if the printer had a failure, it could be dealt with immediately.

Recently, a network has been developed,
Large-scale networks, such as intelligent buildings, with LANs throughout are being developed. Furthermore, like WAN (Wide Area Network),
A nationwide network with a LAN directly connected to the public line,
Furthermore, advanced information networks such as ISDN are being developed.

Therefore, between different floors of the same building,
It is becoming possible to use computers between different buildings or between Tokyo and Osaka.

For this reason, the printer server can be used not only in a relatively narrow range until now, but also in a very wide area.

[0009]

However, in the conventional printer server, since it is assumed that the printer server is used in a relatively narrow range, the printer can only exchange data in one direction from the computer side. When there was an error, there was no way to inform the server of the error.

For this reason, when printing from a remote place through the network and the printer fails, and printing is no longer possible, the user cannot know the failure.

Therefore, in the printer in which the fault has occurred, a person near the printer discovers the fault,
There is a drawback that printing is impossible unless proper recovery processing is performed. In particular, printing becomes impossible when the image is read by the scan printer server and when an error occurs when printing the image.

In the case of a scanner printer server in which an integrated scanner printer is connected to the network,
You can use the scanner, printer as a list scanner, remote printer, or just a copy. Therefore, the control of the scanner printer becomes complicated, and there is a drawback that the scanner printer cannot be controlled only by sending data in one direction like a conventional printer server.

The present invention has been made in view of the above-mentioned drawbacks of the conventional example, and an object of the present invention is to provide a communication processing system in which a user can know the status of a scan printer at a remote place in real time. Is in the point of providing.

[0014]

[Means for Solving the Problems]
In order to achieve the object, a communication processing system according to the present invention includes a terminal device, an integrated device of an input device and an output device, and a server of the integrated device connected on a network. In the system, both first bidirectional communication means for bidirectionally communicating between the input device and the server, and second bidirectional communication for bidirectionally communicating between the output device and the server. And a communication means for communication.

[0015]

According to this structure, the first bidirectional communication means performs bidirectional communication between the input device and the server,
By performing bidirectional communication between the output device and the server by the second bidirectional communication means, bidirectional communication of commands, parameters, and error information can be performed.
