Print Job Interruption Handling via Selective Cancellation or Pausing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses lack the ability to selectively manage job interruption events, such as paper out errors, leading to inefficient processing and potential security risks when confidential information is left unprinted due to interrupted jobs.
Innovation Solution
A printing apparatus with a management unit to prioritize either resuming other print jobs while leaving interrupted jobs paused or automatically canceling the interrupted job, allowing users to set preferences through 'Change Job Order' and 'Automatically Cancel Interrupted Job' functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing apparatus executes other print jobs while leaving the interrupted job unexecuted, then processing efficiency is improved, but security risk increases due to confidential information being left unprinted
Solution Approach 1:
The system dynamically adjusts job execution behavior based on user-defined preferences. When a job interruption occurs, the control unit checks the user's setting (first or second setting) and accordingly either executes subsequent jobs while preserving the interrupted job or cancels it, making the system adaptable to different security-efficiency requirements
Solution Approach 2:
The invention changes the operational parameter of job interruption handling from a fixed mode to a selectable mode. By providing two distinct settings (first setting for efficiency, second setting for security), the system allows parameter adjustment based on the specific situation and user preference
2Object-affected harmful factors
If the printing apparatus cancels the interrupted print job, then security is improved, but user convenience deteriorates as the user must reenter instructions
Solution Approach 1:
The system dynamically responds to user preferences by offering two distinct behaviors for job interruption: cancellation (second setting) for security priority, or preservation (first setting) for convenience priority. The control unit adapts its action based on the stored user setting
Solution Approach 2:
The invention changes the job interruption handling parameter from a single fixed behavior to a selectable behavior mode. The user can choose between cancellation and preservation based on their specific needs, transforming a static system into a flexible one that adapts to different operational contexts
3Object-affected harmful factors
If the printing apparatus automatically cancels interrupted jobs, then security against confidential information exposure is improved, but processing flexibility deteriorates
Solution Approach 1:
The system dynamically adapts its job interruption response based on user-defined preferences. Rather than automatically canceling all interrupted jobs, the control unit checks the user's setting and accordingly either cancels or preserves the interrupted job, making the system flexible and adaptable to different security requirements
Solution Approach 2:
The invention changes the automatic job cancellation parameter from a fixed automatic cancellation mode to a selectable mode with two options. This allows the system to adjust its behavior parameter based on user preference, providing both security-oriented and flexibility-oriented operational modes

AI summary
A printing apparatus includes an accepting unit configured to accept one of a first setting and a second setting, the first setting indicating that another print job managed by the management unit is to be executed while leaving an execution of the print job interrupted, and the second setting indicating that execution of the print job is to be canceled, and a control unit configured to, when the first setting is made in a case where a job interruption event occurs during execution of a print job, execute another print job managed by the management unit while leaving the execution of the print job interrupted, or to, when the second setting is made in a case where a job interruption event occurs during execution of a print job, cancel the execution of the print job.
