Server Print Control via SNS Time Interval Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server devices lack the capability to prevent unintended printing, leading to low user convenience due to the risk of executing printing instructions that are not intended by the user, particularly when multiple print instructions are received in quick succession.
Innovation Solution
A server device with a communication unit and a control unit that can communicate with a terminal device via an SNS server, which receives a second print instruction after a first print instruction and determines whether to make printing available at a printing device based on a predetermined time period, ensuring that printing is only executed if the time gap between the two instructions meets or exceeds this period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the server device receives and executes multiple print instructions in quick succession, then the printing functionality responds quickly to user input, but unintended printing occurs reducing user convenience
Solution Approach 1:
The server device performs preliminary action by recording the timestamp of received print instructions and checking whether the time interval between consecutive instructions meets a predetermined threshold before executing printing. This preliminary time-based verification prevents unintended printing while maintaining quick response to legitimate print requests.
2Productivity
If the server device executes every received print instruction, then printing productivity is maximized, but accidental or unintended printing occurs
Solution Approach 1:
The server device implements feedback by continuously monitoring the time interval between consecutive print instructions and using this information to determine whether to execute printing. This feedback mechanism ensures that only intentionally spaced print requests are executed, preventing accidental printing while maintaining high productivity for legitimate requests.

AI summary
A server device includes: a communication unit configured to be able to communicate with a terminal device via an SNS server device providing a social networking service; and a controller configured to be able to control whether printing is available at a printing device or not. The controller receives a second print instruction at a second time point after receiving a first print instruction at a first time point by the communication unit, and makes printing based on the second print instruction unavailable at the printing device when it is determined that a time period from the first time point to the second time point is shorter than a predetermined time period.
