Print Job Scheduling and Display Order Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared network environments, users face difficulties in understanding the starting order of printing for reserved print jobs, as existing techniques do not effectively manage and display multiple reserved print jobs in a clear manner.
Innovation Solution
A printing apparatus with a reception unit for receiving print data with specified print times, a storage unit for storing the data, and a control unit that controls printing based on the specified times, along with a display control unit that orders and displays a list of print jobs by their print times, allowing users to easily identify the printing order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reserved print jobs are listed in order of acceptance, then the system can simply store and display jobs, but the starting order of printing becomes difficult for users to understand
Solution Approach 1:
The system pre-calculates and determines the printing start order based on specified print times when jobs are registered, and stores this predetermined order information. This preliminary determination allows the display to simply show the pre-computed order without requiring complex real-time calculation logic during display operations.
Solution Approach 2:
The job list display dynamically adapts its sorting criterion based on the print time specifications. When print times are specified, the system automatically switches to displaying jobs in chronological order of their determined start times, rather than using a fixed display order. This dynamic adaptation resolves the contradiction by making the display behavior context-dependent.
2Productivity
If the system manages multiple reserved print jobs with different print times, then printing can be scheduled according to specified times, but users cannot easily identify the starting order of printing
Solution Approach 1:
The system provides feedback to users by displaying the determined print starting order in the job list. This visual feedback allows users to verify that their reserved print jobs will be executed in the expected chronological order, preventing information loss about the printing sequence while maintaining sophisticated time-based scheduling capability.
