Terminal Service Screen Handoff for Printer User Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack efficient methods for displaying service-related information on terminal devices, particularly for printers, which are communicable via the internet, in response to user interactions.
Innovation Solution
A non-transitory computer-readable recording medium storing a set of computer programs for a terminal device, including a first and second computer program, where the first program instructs the display of service-related information and provides a display instruction to the second program, which then displays the service screen in response, enabling seamless interaction and information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If service-related information is displayed on a terminal device for a printer, then user engagement with printer services is improved, but the complexity of the communication system increases
Solution Approach 1:
The system is divided into multiple components: a display unit for showing service information, a communication unit for transmitting data, and a control unit for coordinating operations. This segmentation allows each component to perform its function independently, reducing overall system complexity while maintaining ease of operation.
Solution Approach 2:
The terminal device is designed with multi-functional capabilities, serving both as a display device and a communication interface. The display unit can show various service-related information (subscription status, usage information, error messages) through a single unified interface, eliminating the need for multiple specialized devices and reducing system complexity.
2Ease of operation
If service screens are displayed in response to user operations, then user interaction with printer services is facilitated, but the processing time and system response requirements increase
Solution Approach 1:
Service-related information is pre-loaded and stored in the terminal device's memory before user requests. When a user operation occurs, the display unit can immediately retrieve and show the required information without waiting for real-time processing, significantly reducing response time while maintaining interactive capability.
Solution Approach 2:
The terminal device autonomously manages the display of service information based on stored data and simple control signals from the printer. The control unit automatically determines what information to display based on user operations and pre-stored service data, eliminating the need for complex real-time processing and reducing system response time.

AI summary
A terminal device may, according to a first computer program, display a first predetermined screen including service related information a display of the terminal device and, in a case where a first predetermined operation is received on the first predetermined screen, provide a display instruction to the second computer program. The terminal device may, according to the second computer program, in a case where the display instruction is received from the first computer program, display the service screen on the display.
