Information processing apparatus and non-transitory computer readable medium for acquiring and storing additional processing program

1. An information processing apparatus comprising:

a processor configured to:

determine whether an additional processing program for performing additional processing can be acquired from an additional processing apparatus configured to perform the additional processing for a function of the information processing apparatus; and

store the acquired additional processing program in the information processing apparatus,

wherein:

the processor is configured to, when the additional processing apparatus is unusable, cause the information processing apparatus to perform the additional processing using the additional processing program stored in the information processing apparatus, and

the processor is configured to, when the processor performs a first function that uses the additional processing and a second function that does not use the additional processing in parallel, change an order of the processing such that at least a part of processing constituting the first function is completed prior to the second function.

2. The information processing apparatus according to claim 1 , wherein the processor is configured to acquire the additional processing program when the additional processing apparatus is connected.

3. The information processing apparatus according to claim 1 , wherein the processor is configured to acquire the additional processing program at a predetermined time point after the additional processing apparatus is connected.

4. The information processing apparatus according to claim 3 , wherein the predetermined time point is a time point at which an instruction to perform the additional processing or a function that uses the additional processing is received.

5. The information processing apparatus according to claim 1 , wherein the at least part of the processing is processing that uses an object collected from the information processing apparatus by an operator.

6. The information processing apparatus according to claim 1 , wherein the processor interchanges an order of the at least part of the processing constituting the first function and the processing other than the at least part of the processing.

7. A non-transitory computer readable medium storing a program that causes an information processing apparatus to execute information processing, the information processing comprising:

acquiring an application additional processing program for performing additional processing in response to a connection of an additional processing apparatus configured to perform the additional processing for a function of the information processing apparatus; and

storing the acquired additional processing program in the information processing apparatus;

when the additional processing apparatus is unusable, cause the information processing apparatus to perform the additional processing using the additional processing program stored in the information processing apparatus;

when a first function that uses the additional processing and a second function that does not use the additional processing are performed in parallel, change an order of the processing such that at least a part of processing constituting the first function is completed prior to the second function.

8. An information processing apparatus comprising:

means for acquiring an additional processing program for performing additional processing in response to a connection of an additional processing apparatus configured to perform the additional processing for a function of the information processing apparatus; and

means for storing the acquired additional processing program in the information processing apparatus;

means form, when the additional processing apparatus is unusable, causing the information processing apparatus to perform the additional processing using the additional processing program stored in the information processing apparatus, and

means for, when a first function that uses the additional processing and a second function that does not use the additional processing are performed in parallel, changing an order of the processing such that at least a part of processing constituting the first function is completed prior to the second function.
