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. An information processing apparatus comprising:

a plurality of connecting units, wherein each of the plurality of connecting units is connectable to different networks including a first network on which a predetermined data processing apparatus is provided and a second network that is different from the first network;

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

a processor configured to determine, by comparing a source address of data received by each of the plurality of connecting units with the address stored in the first storage unit, which one of the plurality of connecting units is connected to the first network on which the predetermined data processing apparatus is provided, and to assign to the determined connecting unit information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus.

4. The information processing apparatus according to claim 1, further comprising a second storage unit configured to store an address which is to be used as a destination address for data transmitted from the predetermined data processing apparatus to the information processing apparatus,

wherein the processor assigns to the determined connecting unit the address stored in the second storage unit as the information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus.

5. The information processing apparatus according to claim 1, further comprising a third storage unit configured to store an address to be set as an address of one of the plurality of connecting units that is connected to the second network,

wherein the processor further assigns to the one of the plurality of connecting units that is connected to the second network the address stored in the third storage unit.

6. The information processing apparatus according to claim 1, wherein the data from the source address that matches the address stored in the first storage unit is transmitted from the predetermined data processing apparatus by broadcast transmission.

7. The information processing apparatus according to claim 1, further comprising a conversion unit configured to convert print data received via the second network into data which can be interpreted by the predetermined data processing apparatus,

wherein one of the plurality of connecting units connected to the second network receives the print data via the second network, and

wherein the determined connecting unit connected to the first network transmits the data converted from the print data by the conversion unit to the predetermined processing apparatus via the first network.

12. The information processing apparatus according to claim 1, wherein the information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus is an address determined on the basis of the address of the predetermined data processing apparatus.

13. The information processing apparatus according to claim 1, wherein the information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus is a subnet mask of the predetermined data processing apparatus.

2. An information processing method performed in an information processing apparatus that includes a plurality of connecting units, wherein each of the plurality of connecting units is connectable to different networks including a first network on which a predetermined data processing apparatus is provided and a second network that is different from the first network, the method comprising:

storing, in a first storage unit, an address of the predetermined data processing apparatus;

determining, by comparing a source address of data received by each of the plurality of connecting units with the address stored in the first storage unit, which one of the plurality of connecting units is connected to the first network on which the predetermined data processing apparatus is provided; and

assigning to the determined connecting unit information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus.

8. The information processing method according to claim 2, further comprising:

storing, in a second storage unit, an address which is to be used as a destination address of data transmitted from the predetermined data processing apparatus to the information processing apparatus,

wherein the address stored in the second storage unit is assigned to the determined connecting unit as the information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus.

9. The information processing method according to claim 2, further comprising:

storing, in a third storage unit, an address to be set as an address of one of the plurality of connecting units that is connected to the second network; and

assigning to the one of the plurality of connecting units that is connected to the second network the address information stored in the third storage unit.

10. The information processing method according to claim 2, wherein the data from the source address that matches the address stored in the first storage unit is transmitted from the predetermined data processing apparatus by broadcast transmission.

11. The information processing method according to claim 2, further comprising:

receiving print data via the second network;

converting the print data received via the second network into data which can be interpreted by the predetermined data processing apparatus; and

transmitting the data converted from the print data, to the predetermined data processing apparatus via the first network.

3. A non-transitory computer readable medium containing computer-executable instructions for controlling an information processing apparatus that includes a plurality of connecting units, wherein each of the plurality of connecting units is connectable to different networks including a first network on which a predetermined data processing apparatus is provided and a second network that is different from the first network, the computer readable medium comprising:

computer-executable instructions for storing, in a first storage unit, an address of the predetermined data processing apparatus;

computer-executable instructions for determining, by comparing a source address of data received by each of the plurality of connecting units with the address stored in the first storage unit, which one of the plurality of connecting units is connected to the first network on which the predetermined data processing apparatus is provided; and

computer-executable instructions for assigning to the determined connecting unit information necessary to establish communication between the predetermined data processing apparatus and the information processing apparatus.
