An information processing apparatus is provided that includes an operation unit implemented by an information processing terminal connected via a communication line. The information processing apparatus includes a memory storing a program and a processor configured to execute the program to implement processes of opening a port for receiving a packet conforming to a predetermined communication protocol in response to a request from the information processing terminal, and transmitting data included in the packet to the information processing terminal in response to receiving the packet that is directed to the port.

A present image forming apparatus includes a first control unit that controls a native program, a second control unit that controls an extension application different from the native program, a first memory area in which an operation screen of the native program controlled by the first control unit is rendered, and a second memory area in which an operation screen of the extension application controlled by the second control unit is rendered. At least a part of the operation screen of the native program is output to a display when an event related to outputting of the operation screen of the native program has occurred while the display is displaying a screen rendered in the first memory area.

An information processing apparatus loaded with an application for extending functionality of the information processing apparatus, includes a storage unit configured to, before occurrence of an event relating to an application, store display information including a display item relating to the application and displayed on a display unit of the information processing apparatus, and a display control unit configured to, after occurrence of the event relating to the application, update display relating to the display item according to the display information corresponding to the event stored in the storage unit, under control of a control program that runs on an operating system and provides a framework for managing the application.

An image processing apparatus which is able to prevent a decrease in general versatility of an expansion application. The image processing apparatus has an operating system and the expansion application for expanding functions. When a USB device is connected to the image processing apparatus, a USB I/F communicates with the connected USB device. The connected USB device is controlled using the operating system or the expansion application. It is determined whether or not the connected USB device is a predetermined operating device that operates the image processing apparatus. When the connected USB device is the predetermined operating device, the connected USB device is controlled using the operating system.

An image forming apparatus includes a storage unit configured to store a device control application for causing the image forming apparatus to carry out a job, a storage control unit configured to perform control for causing the storage unit to store an image processing plug-in application for extending the device control application, and a processing unit configured to execute the image processing plug-in application in conjunction with execution of the device control application.

An information processing system includes a processor and a memory that stores a plurality of instructions which cause the processors to control executing a first application executed on an operation unit including a display, acquire identification information for identifying the first application in accordance with execution of the first application, register the identification information being acquired in the memory, control executing a second application executed on a main unit controlling the information processing system to perform multiple functions according to an instruction input to the operation unit, output, in response to receiving a request to log out while the second application is executing, rejection information indicating that the request to log out is rejected, and control, in response to outputting the rejection information, the display of the operation unit to display first name information indicating a name of the first application corresponding to the identification information registered in the memory.

A cloud link system is connected with another cloud link system. In a list of cloud services includes a first cloud service connected to the cloud link system without the another cloud link system and a second cloud service connected to the another cloud link system.

An information processing apparatus includes a user list providing unit configured to receive device identification information from a current device connected via a network and to send, to the current device, a user list including one or more user identifiers that are stored in a storage unit in association with the received device identification information; and a program list providing unit configured to receive a user identifier that is selected at the current device from the user identifiers in the user list and to send, to the current device, a program list including sets of program information stored in the storage unit in association with the received user identifier.

An information processing apparatus includes a user list providing unit configured to receive device identification information from a current device connected via a network and to send, to the current device, a user list including one or more user identifiers that are stored in a storage unit in association with the received device identification information; and a program list providing unit configured to receive a user identifier that is selected at the current device from the user identifiers in the user list and to send, to the current device, a program list including sets of program information stored in the storage unit in association with the received user identifier.

An information processing apparatus includes a start unit which, in a case where one of the applications is to be activated at a time of activating the information processing apparatus, performs a start process of the application based on a task for each of the applications, the task being different from a task giving an instruction to activate the application, a monitoring unit which monitors whether the start process of the application is completed in a predetermined time, and an interruption unit which, in a case where the start process of the application is not completed in the predetermined time, interrupts the start process of the application, and provides a mechanism capable of, even in a situation where the start processes of some applications cannot be completed, continuing the activation process of the apparatus itself and making the function of another application usable.
