Printing Apparatus Print Setting Change Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses do not effectively manage collective changes to print settings for multiple print jobs, as they fail to prevent changes to settings that are not allowed or not applicable, leading to potential inconsistencies and usability issues.
Innovation Solution
A printing apparatus with an operation device, memory, and processors that receive print jobs, allow user selection, and prevent changes to settings that are not allowed, displaying warnings when attempting to change settings that cannot be applied across multiple selected print jobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collective change of print settings is permitted for multiple print jobs, then ease of operation is improved, but reliability deteriorates due to permission of incorrect setting changes
Solution Approach 1:
The system provides feedback by detecting which print settings can and cannot be changed for selected print jobs, and controls the user interface to only permit changes to allowable settings. This feedback mechanism prevents incorrect changes while maintaining ease of operation through collective modification capability.
Solution Approach 2:
The system performs preliminary analysis to determine which print settings are changeable before allowing user modification. By pre-identifying allowable settings based on print job characteristics and device capabilities, the system prevents erroneous changes while enabling convenient collective editing.
2Adaptability or versatility
If all print settings are made changeable, then adaptability is improved, but manufacturing precision deteriorates due to inconsistent settings
Solution Approach 1:
The system applies local quality by allowing setting changes only for specific print jobs that support modification, while maintaining fixed settings for jobs where changes would cause inconsistency. This selective approach ensures adaptability for compatible jobs while preserving manufacturing precision for the overall print batch.
Solution Approach 2:
The system segments print settings into changeable and non-changeable categories based on individual print job characteristics. This segmentation allows adaptive modification of compatible settings while maintaining consistency across the entire print batch, resolving the contradiction between adaptability and precision.
3Reliability
If setting changes are restricted, then reliability is improved, but ease of operation worsens due to limited modification options
Solution Approach 1:
The system dynamically adjusts the set of changeable settings based on the selected print jobs and their characteristics. This dynamic control maintains reliability by preventing invalid changes while preserving ease of operation by enabling modifications where appropriate, adapting to each specific scenario.

AI summary
A printing apparatus includes one or more memories, and one or more processors that execute a set of instructions to receive a print job including at least print settings from an external apparatus, store a plurality of received print jobs in a storage device, receive selection of a stored print job as a target of printing from a user, and receive a change of a print setting of the selected print job from a user. When selection of a plurality of stored print jobs is received, and if at least one of the plurality of selected print jobs includes a print setting that is forbidden to be changed when the plurality of print jobs are stored in the storage device, a display is controlled to indicate not to change a value of the print setting.
