Mobile Terminal Cross-Network Print Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of print data from a server to a mobile terminal device is hindered when the device cannot simultaneously connect to multiple networks, and even when it can, network differences between the server and the image forming apparatus lead to transmission failures, preventing seamless printing.
Innovation Solution
A mobile terminal device with a print data selecting unit, communication establishing unit, detection unit, and data transmitting unit that selects print data, establishes wireless communication, detects the image forming apparatus's network connection, obtains print data from a storage destination on a different network, and transmits it to the image forming apparatus, allowing for printing across network boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal device connects to the network isolated from the server to communicate with the image forming apparatus, then the printing function is enabled, but the print data cannot be downloaded from the server
Solution Approach 1:
The mobile terminal device downloads print data from the server to its local storage before disconnecting from the server's network. This preliminary action ensures that the data is available locally when the device switches to the isolated network for communication with the image forming apparatus, resolving the contradiction between enabling printing and maintaining data accessibility.
2Adaptability or versatility
If the mobile terminal device simultaneously connects to multiple networks, then data transmission flexibility is improved, but network complexity and connection stability deteriorate
Solution Approach 1:
The data transmission process is segmented into two distinct phases: first, connecting to the server's network to download print data; second, disconnecting from the server's network and connecting to the isolated network to transmit data to the image forming apparatus. This segmentation avoids the complexity of simultaneous multi-network connections while maintaining transmission flexibility through sequential network switching.
3Quantity of substance
If the print data is stored only in the server on a different network, then storage efficiency is improved, but transmission reliability to the image forming apparatus deteriorates
Solution Approach 1:
The mobile terminal device acts as an intermediary that temporarily stores print data locally. It downloads the data from the server when connected to the server's network, then transmits it to the image forming apparatus when connected to the isolated network. This intermediary storage role resolves the contradiction by enabling reliable transmission across network boundaries while maintaining server storage efficiency.

AI summary
A mobile terminal device includes a print data selecting unit that selects print data in response to a user operation, a communication establishing unit that establishes wireless communication with a network, a detection unit that detects an event in which an image forming apparatus connected to a first network is selected as a printing destination of the print data, an obtainment unit that obtains the print data from a storage destination connected to a second network different from the first network through wireless communication with the second network established by the communication establishing unit after the detection unit detects the event, in a case where the print data is stored in the storage destination, and a data transmitting unit that transmits the print data obtained by the obtainment unit to the image forming apparatus through wireless communication with the first network established by the communication establishing unit.
