Printing System Dual Mode Authentication Server Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In location-free printing systems, direct printing by image forming apparatuses close to the client terminal is not permitted due to complexity in managing utilization history, requiring users to perform authentication and selection operations, which complicates management for system administrators.
Innovation Solution
A printing system that allows users to select between two print modes: location-free printing, which requires user authentication on the image forming apparatus, and direct printing, which executes print jobs without user authentication, with a server managing authority and recording utilization history for each user across multiple image forming apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct printing is permitted in location-free printing system, then user convenience is improved, but management complexity increases
Solution Approach 1:
The system segments printing into two distinct modes: location-free printing (requiring authentication) and direct printing (no authentication). This segmentation allows different operational complexities to coexist, with direct printing simplified for users while location-free printing maintains centralized management control.
Solution Approach 2:
The server acts as an intermediary that manages both printing modes. For direct printing, the server facilitates immediate execution without authentication; for location-free printing, it manages authentication and job distribution. This intermediary role resolves the contradiction by centralizing management functions while enabling simplified user operations.
2Device complexity
If location-free printing is used, then centralized management is achieved, but user operation steps increase
Solution Approach 1:
The system dynamically adapts the authentication requirement based on the printing mode selected. Location-free printing enables centralized management with authentication steps, while direct printing mode dynamically removes authentication requirements, reducing user operation steps while maintaining management capability through server coordination.
3Adaptability or versatility
If both printing modes are enabled, then system versatility is improved, but authentication management complexity increases
Solution Approach 1:
Different authentication management approaches are applied to different printing modes. Direct printing uses a simplified authentication-less approach, while location-free printing uses full authentication management. This local quality differentiation allows the system to handle each mode with appropriate complexity, reducing overall management burden while maintaining versatility.

AI summary
A printing system according to an embodiment includes a plurality of image forming apparatuses, a server, and a plurality of client terminals. The client terminal displays a setting screen for a user to select, as a print mode, one of a first print mode in which user authentication is not required and a second print mode in which the user authentication is required. When the second print mode is selected as the print mode, the user terminal transmits to the server information related to the user, a print instruction in accordance with the second print mode, and the print job. The server determines whether the user has authority to perform printing in the second print mode. When the user is determined to have the authority, the server transmits the print instruction and the print job to the particular image forming apparatus registered for that user.
