Printing Apparatus Password Matching and Data Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multifunction peripherals only display print data associated with the inputted authentication code, leading to the risk of users forgetting to print data linked to different authentication information not displayed.
Innovation Solution
A printing apparatus that receives and stores target data along with password and identification information, allowing users to input specific password information to match and print associated images, while also extracting and printing additional data linked to the same identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the multifunction peripheral displays only print data associated with the inputted authentication code, then authentication security is maintained, but users may forget to print data linked to different authentication information
Solution Approach 1:
The system segments print data into different categories based on authentication codes and user identification information. It allows selective display of print data either by authentication code (for security) or by user identification information (for completeness), resolving the contradiction between security and visibility
Solution Approach 2:
The invention adds a new dimension to the data display by introducing user identification information as an additional sorting criterion. Instead of displaying only print data associated with the inputted authentication code, the system now displays all print data associated with the same user identification information, providing a broader view while maintaining security through authentication
2Ease of operation
If the system stores and displays all print data associated with user identification information, then users can view all their print data, but the system complexity increases
Solution Approach 1:
The system uses the same authentication and data storage mechanism to serve multiple functions: both authentication-based filtering and user identification-based comprehensive display. This multi-functionality allows the system to provide both secure filtered viewing and complete data access without requiring separate systems
Solution Approach 2:
The controller acts as an intermediary that manages the complexity of data storage and retrieval. It automatically organizes print data by both authentication codes and user identification information, handling the complexity of data management while providing simple access methods to users
Data Source
AI summary
In a printing apparatus, printing requests for first and second target data are received via a network interface from a terminal device. First target data, first password information, and first identification information are stored in association with one another in a memory, and second target data, second password information, and first identification information are stored in association with one another in the memory. When it is determined that the specific password information received via the inputting device matches the first password information, the printing device is controlled to print a first image represented by the first target data, the second target data whose associating identification information is the first identification information associated with the first target data is extracted from the memory, and the printing device is controlled to print a second image represented by the second target data.
