Print Job Grouping and Execution Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared printing systems, there is a risk of confusion between printed materials belonging to different users due to the execution of print jobs from one user alongside those of another, leading to mixing of printed matters.
Innovation Solution
A printing system that includes a storage portion for user-specific print jobs, an obtaining portion for group information, and a job execution portion that prioritizes and executes user-specific print jobs while leaving other jobs unexecuted until the user-specific jobs are completed, ensuring that all user-specific print jobs are executed before proceeding with others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing device executes print jobs from multiple users in succession without strict separation, then the productivity of the printing system is improved, but the reliability of user-specific print output is worsened due to potential mixing of printed materials
Solution Approach 1:
The patent segments the print job execution process by introducing a dedicated storage portion that stores job data separately for each user. The obtaining portion retrieves group information for a specific user, and the job execution portion executes only that user's jobs in sequence. This segmentation ensures that even though multiple users submit jobs simultaneously, each user's print jobs are isolated and executed as a distinct group, preventing mixing of printed materials while maintaining efficient throughput.
Solution Approach 2:
The patent applies preliminary action by having the storage portion pre-store job data for multiple users before execution. When a user requests print services, the obtaining portion retrieves the pre-stored group information for that user. This preliminary storage and retrieval mechanism allows the system to quickly identify and execute only the relevant user's jobs without delay, ensuring both high productivity and reliable user-specific output integrity.
2Ease of operation
If the printing device uses conventional job execution methods without user group separation, then the ease of operation is improved, but the reliability of print job execution is worsened due to confusion between different users' printed matters
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of the obtaining portion that mediates between the simple user submission process and the complex job execution process. Users simply submit print jobs without needing to manually manage job sequences or user separations. The obtaining portion automatically retrieves group information for the specific user, and the job execution portion uses this information to ensure accurate execution. This intermediary layer maintains ease of operation while ensuring reliable, user-specific job execution.
3Speed
If the printing device executes print jobs immediately without waiting for user-specific job completion, then the speed of job processing is improved, but the manufacturing precision of user-specific print output is worsened due to potential mixing of printed matters
Solution Approach 1:
The patent applies dynamics by making the job execution sequence adaptive rather than fixed. The job execution portion dynamically determines which user's jobs to execute based on real-time requests from the obtaining portion. When a user requests print services, the system identifies the user's group information and executes only that user's jobs in the correct sequence. This dynamic approach allows the system to maintain high processing speed while ensuring precise, user-specific output quality, as jobs are executed in the optimal sequence rather than a rigid predetermined order.

AI summary
A printing system having a print portion is provided. The printing system includes a storage portion configured to store job data based on which a plurality of first print jobs is executed, the first print jobs being instructed by a specific user; an obtaining portion configured to, in response to a request made by the specific user, obtain group information on a group of the first print jobs; and a job execution portion configured to, after the print portion starts the first print jobs, leave a second print job other than the first print jobs unexecuted and execute all of the first print jobs based on the group information, and after that, execute the second print job.
