Printer UI Segmentation for Guest Print Job Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hold printing systems, unauthenticated guest users cannot display print data from multiple PCs on the printer's user interface screen, leading to potential printing errors due to the inability to distinguish and select print jobs from different user terminals.
Innovation Solution
An image forming apparatus with a print data management unit, login control unit, and user interface control unit allows guest users to log in without authentication, displaying a user interface screen that enables selection of print functions by PC units, facilitating the display of print data from multiple information processing apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is required to display print data on the UI screen, then security and user-specific control are improved, but the ability of multiple guest users to access and display their print data from different PCs is worsened
Solution Approach 1:
The patent segments the user interface by creating separate display areas for authenticated users and guest users. The UI is divided into a first display area for authenticated user print data and a second display area for guest user print data, allowing simultaneous access without authentication conflicts
Solution Approach 2:
The patent introduces an intermediary mechanism (the segmented display system) that mediates between authenticated users and guest users. This intermediary allows the system to maintain authentication requirements for security while enabling guest access through a separate interface pathway
2Ease of operation
If print data from multiple PCs is displayed on the UI screen, then guest user usability is improved, but the complexity of managing and identifying print data sources increases
Solution Approach 1:
The patent applies local quality by providing different display characteristics for different user types. Guest user print data is displayed with specific attributes (second display area with distinct visual characteristics) that differentiate it from authenticated user data, making it easy to identify and select without confusion
Solution Approach 2:
The display is segmented into distinct areas with different visual characteristics. Print data from multiple PCs is organized in separate display regions with unique identification features, reducing the complexity of managing multiple data sources by providing clear visual separation
