Printer Queue Visualization for Media Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in high-velocity industrial environments face challenges in managing print media and print job queues due to the lack of integrated information on media availability and job organization, requiring manual calculations and cognitive load.
Innovation Solution
A visual element in the print job queue displays the status of each print job, indicating which jobs end up on the same output unit of print media, such as a stack or roll, and signals media availability, enabling easier job management and media handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a manual calculation method is used to determine media requirements and job organization, then the operator can obtain information about print media handling, but the cognitive load increases significantly and the process becomes time-consuming
Solution Approach 1:
The system automatically calculates media requirements and organizes print jobs by itself. The print controller determines which print jobs can be printed based on current media availability, groups jobs by output stack or roll, and calculates media consumption without operator intervention. This self-service approach eliminates the need for manual calculations while providing complete information about media handling and job organization.
Solution Approach 2:
The patent replaces the manual mechanical calculation process with an automated electronic system. The print controller uses software algorithms to automatically determine media requirements, job grouping, and scheduling. This substitution of manual mechanical operations with electronic automation reduces cognitive load while maintaining complete information accuracy.
2Loss of information
If the input schedule displays detailed media information separately, then complete media information is available, but the operator must focus on different parts of the interface making it cumbersome to get a complete overview
Solution Approach 1:
The patent merges previously separate information displays into a single integrated view. The input schedule now combines media availability information, print job queue status, job grouping by output stack/roll, and media consumption calculations in one unified interface. This consolidation allows operators to see complete information about media handling and job organization without navigating between multiple panels or screens.
Solution Approach 2:
The input schedule becomes a multi-functional interface that simultaneously displays media inventory, job queue status, output stack assignments, roll length information, and media consumption projections. This universal interface replaces multiple specialized displays, providing comprehensive information in a single view that serves multiple operational needs.
3Productivity
If the printer processes multiple print jobs with different media requirements, then productivity increases, but the complexity of managing media sources and job scheduling increases
Solution Approach 1:
The system implements automatic feedback loops where the print controller continuously monitors media levels in each source, tracks job completion status, and dynamically adjusts the print job queue based on real-time media availability. When media is consumed or runs low, the system automatically recalculates which jobs can be printed and reorganizes the queue, providing continuous feedback-driven optimization without increasing operational complexity.
Solution Approach 2:
The patent introduces dynamic adaptability in media management. The print controller automatically adjusts job scheduling and media allocation based on changing conditions such as media consumption rates, available media quantities, and job priorities. This dynamic system adapts to varying productivity requirements while maintaining manageable complexity through automated decision-making algorithms.
Data Source
AI summary
A method and a printer for printing print jobs on print media, the printer comprising at least one print media source, a print controller for controlling the printing of the print jobs by means of a print job queue, and a user interface for displaying a representation list of the print jobs in the print job queue. The representation list comprises a visual element which is present at each scheduled print job in the representation list, is configured to signal a status of each print job and to display which print jobs end up to a same output unit of print media.
