Printer Media Parameter Update Logic Preserving User Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In printing apparatuses, updating control information for different mediums can result in user-changed parameters being overwritten, leading to increased user burden and loss of original settings when using media update programs.
Innovation Solution
An information processing apparatus with a receiving unit to hold custom media characteristic information, an obtaining unit to update media characteristic information, and a decision unit to determine whether to update or hold user-changed parameters based on configuration differences, allowing for selective parameter updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media characteristic information is updated by a media update program, then new medium support and optimal control information are achieved, but user-changed parameters are overwritten requiring re-setup
Solution Approach 1:
The patent segments media characteristic information into two distinct types: standard media characteristic information (from update programs) and custom media characteristic information (user-modified parameters). This segmentation allows the system to selectively apply updates only to standard parameters while preserving custom parameters, resolving the contradiction between updating capability and parameter retention.
Solution Approach 2:
The patent performs preliminary identification and marking of user-changed parameters before the update process executes. By预先 (in advance) identifying which parameters have been modified by users and storing them as custom parameters, the system can protect these parameters from being overwritten during subsequent update operations, thus preventing the need for user re-setup.
2Ease of manufacture
If control information is uniformly defined for each medium, then media update programs can be used for updates, but optimal control cannot be achieved for specific installation environments
Solution Approach 1:
The patent implements local quality by allowing uniform standard media characteristic information to be maintained for general use while enabling localized custom modifications for specific installation environments. Users can adjust specific parameters (such as temperature compensation values or humidity corrections) to match their local conditions, while the rest of the control information remains standardized and updateable.
Solution Approach 2:
The patent introduces dynamics by making media characteristic information flexible and adaptable rather than static. The system allows standard parameters to be updated through update programs while simultaneously allowing users to dynamically adjust specific parameters based on their installation environment, creating a hybrid approach that combines both uniformity and adaptability.
3Reliability
If users manually change control information from UI, then environment-specific optimization is achieved, but user burden increases due to repeated re-setup after updates
Solution Approach 1:
The patent implements feedback by monitoring and tracking user modifications to media characteristic information. When users change parameters through the UI, the system detects these changes, identifies them as custom parameters, and provides feedback protection during update operations. This feedback mechanism ensures that user adaptations are preserved across updates, eliminating the need for repeated re-setup and reducing time loss.

AI summary
An information processing apparatus receives a change of a parameter included in media characteristic information, causes, from media characteristic information held by a storage, the parameter for which the change is received to be held as custom media characteristic information, the apparatus performs an update of the media characteristic information held by the storage in accordance with new media characteristic information and decides, if an update of the custom media characteristic information is to be performed by using the new media characteristic information, whether to hold, or to update without holding, the parameter for which the change is received, based on a difference in configuration between the custom media characteristic information held by the storage and the new media characteristic information.
