Abstract

When there are any problems in a device in a print server which the user wants to allow to execute a job, another device that can execute the job exactly is automatically selected and the job is sent thereto. The print server manages plural printers. The print server, upon reception of print job data including printer specification from a client, checks status of the specified printer in a data distributing section. When its status has some problem, the print server, in accordance with a print redirecting method that has been previously set in a writable nonvolatile memory by the user, selects another printer that is in a normal state, and sends print data of its print job to another printer that has been selected.

Claims

1. An apparatus of controlling plural processing modules comprising:

a check unit which checks a state of one processing module which will perform a specified processing, in the plural processing modules;

a redirecting unit which selects, when the state of the specified module has some problems as a result of a check, from other processing modules a processing module of a redirecting side; and

a control unit which controls the processing module of the redirecting side and allows it to perform the specified processing.

2. The apparatus according to claim 1, further comprising a setting unit which receives setting of a redirecting method from a user and records it, in which the redirecting unit, in accordance with the redirecting method set by the user, selects the processing module of the redirecting side from the other modules.

3. The apparatus according to claim 1, further comprising a unit which informs a user of a set redirecting method.

4. The apparatus according to claim 1, further comprising a unit which informs a user that the specified processing will be performed by the processing module of the redirecting side.

5. A method of controlling plural processing modules comprising the steps of:

checking a state of one processing module which will perform a specified processing, in the plural processing modules;

selecting, when the state of the specified module has some problems as a result of a check, from other processing modules a processing module of a redirecting side; and

controlling the processing module of the redirecting side and allowing it to perform the specified processing.
