Print Job Timeout and Queue Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large print jobs often take hours to complete, preventing other users from interrupting or printing their own jobs, and users may not know how long their print jobs will take, making it difficult to print within a desired time window.
Innovation Solution
Implementing a timeout mode in information processing systems that allows jobs to be timed out and moved down in the queue, enabling other jobs to be processed while allowing users to interrupt or cancel ongoing large print jobs, with options to pause, move, or cancel timed-out jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large print jobs are processed without timeout, then the print job completes fully, but other users cannot access the printer and resources are monopolized
Solution Approach 1:
The system implements periodic timeout checks during print job processing, where the print job is interrupted at predetermined time intervals. This allows the printer to become available to other users periodically while still enabling the original job to resume or be managed later, resolving the conflict between completing large print jobs and allowing user access flexibility.
Solution Approach 2:
The print job queue position is made dynamic through timeout mechanisms. When a timeout occurs, the print job is automatically moved down in the queue, allowing other jobs to be processed in its place. This dynamic repositioning enables resource sharing while maintaining the ability to resume or manage the original job later.
2Duration of action of moving object
If print jobs are allowed to run indefinitely, then users can print large documents, but users cannot control printing within desired time windows
Solution Approach 1:
The system establishes predetermined timeout periods in advance before the print job completes. These pre-set time limits allow users to control how long their print jobs can run, ensuring printing occurs within desired time windows while still accommodating large document requirements.

AI summary
Systems and methods relate generally to job handling by an information handling system. In an example method thereof, a timeout mode is provided for a job to be processed by the information processing system. A plurality of jobs including the job are queued in a buffer queue of the information processing system. The job is timed out. The job is moved down in the buffer queue in response to the timing out thereof. In an example of another method thereof, the job is canceled in response to the timing out thereof, rather than being moved down in the buffer queue.
