Are connected to each other via a network such as a network.

[0005] In data communication between different OSs, data that can be transmitted and received is only the print data type and print data in a print document. In addition, the operation has only limited functions such as deletion. Therefore, transfer of a print document including print data and attribute information between different OSs allows transfer of only print data from the application server 101 to the print server 110. For example, transfer of attribute information including storage designation after printing, etc. Was impossible.

[0006] Regarding the printing operation, the user is aware of the application server 101 and the print server 110 and is aware of the location of the print document, and gives a user name (transfer ID) to the application server 101 and the print server 110. And password must be transferred each time the server is connected. Further, after the connection, since the operation differs for each OS, the user has to perform a different printing operation for each OS of each connected server.

An example of the processing procedure of the distributed printing system shown in FIG. 9 is shown below.

FIG. 10 is a flowchart for explaining the prior art. This figure shows the procedure of transferring a print document and printing out. In addition, the code | symbol refers to FIG.

In step S55, the print server 11
0 receives data transmitted from the application server 101.

In step S56, the print server 11
0 converts only print data based on the standard protocol.

In step S57, the print server 11
In the case of "0", a print output is instructed to the printer 120, and the process ends.

FIG. 11 is a flowchart for explaining the prior art. FIG. 7 shows a procedure of a printing operation in the operation computer 125. In addition, the code | symbol refers to FIG.

In step S61, the application server 101 to be connected is specified, and a user name and a password are transferred to connect.

In step S62, it is confirmed where the print document to be viewed is located. That is, it is determined whether the application server 101 or the print server 110 exists.

In step S63, it is determined whether the print document to be viewed exists on the application server 101 side. If it is located on the application server 101 side, the process proceeds to step S64. If it is located on the print server 110 side, the process proceeds to step S66.

In step S64, the status of the print document (printing, printing wait, hold, etc.) is displayed on the print operation screen.

In step S65, the status of the print document is confirmed, and
A print operation instruction is issued by an operation suitable for S.

In step S66, a user name and a password are transferred to and connected to the print server 110 holding the print document to be viewed.
