Abstract

A data processing apparatus includes a plurality of connecting units that individually connect to a first network to which a predetermined data processing apparatus is connected and a second network, and a determining unit that determines that a connecting unit that receives data including an address of the predetermined data processing apparatus as a source address is connected to the first network.

Claims

1. A data processing apparatus comprising:

a plurality of connecting units that are each individually configured to be able to be connected to at least one of a plurality of networks;

a first address storage unit configured to store a predetermined address;

a second address storage unit configured to store an address of a predetermined data processing apparatus; and

a control unit configured to assign the predetermined address stored in the first address storage unit to a first one of the plurality of connecting units, wherein the first one of the connecting units is configured to receive data including the address stored in the second address storage unit as a source address.

2. The data processing apparatus according to claim 1, further comprising:

an address input unit configured to input an address to be assigned to any one of the plurality of connecting units, wherein the control unit assigns the address input through the address input unit to a second one of the plurality of connecting units.

3. The data processing apparatus according to claim 1, wherein the control unit is configured to determine whether the source address included in the data received by the first one of the connecting units coincides with the address stored in the second address storage unit, and when the control unit determines that the source address coincides with the address stored in the second address storage unit, the control unit assigns the address stored in the first address storage unit to the first one of the connecting units.

4. The data processing apparatus according to claim 1, further comprising:

a conversion unit configured to convert print data received via the plurality of networks to data that can be interpreted by the predetermined data processing apparatus,

wherein a second one of the plurality of connecting units receives the print data via the plurality of networks, and the first one of the connecting units sends the converted data via the plurality networks.

5. A data processing apparatus comprising:

a plurality of connecting units that are each individually configured to be able to be connected to a first network to which a predetermined data processing apparatus is connected and a second network; and

a determining unit configured to determine whether any one of the plurality of connecting units that receives data including an address of the predetermined data processing apparatus as a source address is connected to the first network.

6. A data processing method performed in a data processing apparatus that includes a plurality of connecting units that are each individually configured to be able to be connected to at least one of a plurality of networks, the method comprising:

receiving data through a first one of the plurality of connecting units;

determining whether a source address of the received data coincides with an address of a predetermined data processing apparatus; and

assigning, when it is determined that the source address of the received data coincides with the address of the predetermined data processing apparatus, a predetermined address to a second one of the plurality of connecting units.

7. The method according to claim 6, wherein the predetermined address and the address of the predetermined data processing apparatus are stored in the data processing apparatus.

8. The method according to claim 6, further comprising:

inputting an address to be assigned to the second one of the plurality of connecting units; and

assigning the input address to the second one of the connecting units.

9. The method according to claim 6, further comprising:

converting print data received via the plurality of networks to data that can be interpreted by the predetermined data processing apparatus,

wherein another one of the plurality of connecting units other than the first one of the connecting units receives the print data via the plurality of networks, and the first one of the connecting units sends the converted data via the plurality of networks.

10. A data processing method performed in a data processing apparatus that includes a plurality of connecting units that are each individually configured to be connected to a first network to which a predetermined data processing apparatus is connected and a second network, the method comprising:

receiving data through a first one of the plurality of connecting units;

determining whether a source address of the received data coincides with an address of the predetermined data processing apparatus; and

determining, when it is determined that the source address of the received data coincides with the address of the predetermined data processing apparatus, that the first one of the connecting units is connected to the first network.

11. A computer readable medium containing computer-executable instructions for controlling a data processing apparatus that includes a plurality of connecting units that are each individually configured to be able to be connected to at least one of a plurality of networks, the computer readable medium comprising:

computer-executable instructions for receiving data through a first one of the plurality of connecting units;

computer-executable instructions for determining whether a source address of the received data coincides with an address of a predetermined data processing apparatus; and

computer-executable instructions for assigning, when it is determined that the source address of the received data coincides with the address of the predetermined data processing apparatus, a predetermined address to the first one of the connecting units.

12. A computer readable medium containing computer-executable instructions for controlling a data processing apparatus that includes a plurality of connecting units that are each individually configured to be able to be connected to a first network to which a predetermined data processing apparatus is connected and a second network, the computer readable medium comprising:

computer-executable instructions for receiving data through a first one of the plurality of connecting units;

determining whether a source address of the received data coincides with an address of the predetermined data processing apparatus; and

determining, when it is determined that the source address of the received data coincides with the address of the predetermined data processing apparatus, that the first one of the connecting units is connected to the first network.
