Printing Device NFC Wireless Communication User Operation Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC-based printing systems require additional user operations, compromising operability as they lack intuitive selection and printing mechanisms directly on the printing device.
Innovation Solution
A printing device with a wireless communication unit, operation acquisition unit, and processor that acquires user operations to identify and print selected image information, allowing for direct selection and printing without extensive mobile device interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC is used for printing operations, then communication stability is improved, but user operability deteriorates due to requiring additional user operations
Solution Approach 1:
The printing device autonomously acquires image information from the mobile terminal via NFC and automatically executes printing operations without requiring additional user input. The system serves itself by detecting the mobile terminal, acquiring necessary data, and initiating print jobs automatically, thereby eliminating the need for complex user operations while maintaining reliable NFC communication
Solution Approach 2:
The printing device pre-acquires image information and prepares printing parameters before the actual printing operation. By preliminarily acquiring the necessary data through NFC communication and pre-configuring printing settings, the system eliminates the need for additional user operations during the printing process, improving ease of operation while maintaining communication stability
2Measurement precision
If additional user operations are required for printing, then selection precision is improved, but device complexity increases
Solution Approach 1:
The printing device autonomously identifies and selects image information from the mobile terminal without requiring user intervention. The system self-determines which images to print by acquiring image data directly from the terminal's storage, eliminating the need for complex selection operations on the printing device side while maintaining precise selection through automated data acquisition
3Reliability
If NFC communication is used, then communication stability is improved, but printing speed deteriorates due to lower communication speed
Solution Approach 1:
The system performs preliminary NFC communication to acquire communication parameters and establish a connection, then uses this established connection for high-speed data transfer. By preliminarily setting up the communication framework through NFC and leveraging the pre-established connection, the system achieves both stable communication initiation and high-speed data transmission for printing
Solution Approach 2:
NFC acts as an intermediary that facilitates the transition from mobile terminal to printing device communication. It establishes a reliable connection and transfers necessary control information, allowing the actual high-speed printing data transmission to occur through optimized pathways that leverage the preliminary NFC setup, thereby achieving both stability and speed

AI summary
A printing device includes a printing device side wireless communication unit configured to execute wireless communication with a mobile terminal, an operation acquisition unit configured to acquire user operation thereof, and a processor. The processor is configured to acquire instruction information via the printing device side communication unit, acquire at least one piece of image information from among a plurality of pieces of image information included in an image information set, acquire information, which is generated in response to an operation of the operation unit, as selection information which is used to identify image information selected by the user operation of the operation unit, and, in response to acquisition of the instruction information, execute a first print process to print an image based on the image information which is identified by the selection information.
