Abstract

An information processing apparatus which has received an instruction to perform communication determines whether a server supports multi-connection communication. When the information processing apparatus determines that the server does not support multi-connection communication, the information processing apparatus performs communication by using one connection instead of using multi-connection communication.

Claims

1. An information processing apparatus having a multi-connection communication function for transmitting and receiving data blocks by using a plurality of connections, the information processing apparatus comprising:

a determination unit configured to determine whether an external apparatus as a communication partner supports the multi-connection communication function; and

a communication unit configured to communicate with the external apparatus by using the multi-connection communication function in a case where the determination unit determines that the external apparatus supports the multi-connection communication function, and, to communicate with the external apparatus without using the multi-connection communication function in a case where the determination unit determines that the external apparatus does not support the multi-connection communication function.

2. The information processing apparatus according to claim 1, wherein, in a case where the determination unit determines that the external apparatus does not support the multi-connection communication function, the communication unit communicates with the external apparatus by using one connection.

3. The information processing apparatus according to claim 1, further comprising a receiving unit configured to receive an instruction to perform communication from a user,

wherein, in a case where the receiving unit receives the instruction to perform communication, the determination unit determines whether the external apparatus supports the multi-connection communication function.

4. The information processing apparatus according to claim 3, further comprising a transmission unit configured to, in a case where the receiving unit receives the instruction to perform communication, transmit a confirmation packet for confirming whether the external apparatus supports the multi-connection communication function to the external apparatus,

wherein the determination unit determines whether the external apparatus supports the multi-connection communication function based on a response packet to the confirmation packet.

5. The information processing apparatus according to claim 4, wherein, in a case where the response packet is a packet indicating a specific error, the determination unit determines that the external apparatus does not support the multi-connection communication function.

6. The information processing apparatus according to claim 1, wherein the information processing apparatus is a printing apparatus capable of performing print processing.

7. A control method for controlling an information processing apparatus having a multi-connection communication function for transmitting and receiving data blocks by using a plurality of connections, the control method comprising:

determining whether an external apparatus as a communication partner supports the multi-connection communication function; and

communicating with the external apparatus by using the multi-connection communication function in a case where it is determined that the external apparatus supports the multi-connection communication function, and communicating with the external apparatus without using the multi-connection communication function in a case where it is determined that the external apparatus does not support the multi-connection communication function.

8. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for controlling an information processing apparatus having a multi-connection communication function for transmitting and receiving data blocks by using a plurality of connections, and the control method comprising:

determining whether an external apparatus as a communication partner supports the multi-connection communication function; and

communicating with the external apparatus by using the multi-connection communication function in a case where it is determined that the external apparatus supports the multi-connection communication function, and communicating with the external apparatus without using the multi-connection communication function in a case where it is determined that the external apparatus does not support the multi-connection communication function.
