Printing Device Font Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of existing printing devices that handle multiple-form characters must have knowledge of all available font designs to allocate priority levels, making it difficult to change the desired font design's priority level.
Innovation Solution
A printing device with a control unit that accepts a character code associated with multiple font designs and changes the priority level of these designs in response to a user command, allowing for easy adjustment of font design priorities without requiring knowledge of all available designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printing device allocates priority levels to all font designs at a time, then the user can control which font design is printed, but the user must have knowledge of all available font designs and allocate priority levels to each one
Solution Approach 1:
The patent segments the priority level allocation process into two distinct modes: a simple mode where users can change the priority level of a specific font design by inputting only its name, and a comprehensive mode where users can allocate priority levels to all font designs. This segmentation allows users to choose the appropriate level of complexity based on their needs, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent implements partial action by allowing users to change the priority level of only the font design they desire without requiring them to allocate priority levels to all font designs. The system accepts a command containing only the name of the target font design and its new priority level, rather than requiring complete allocation information for all font designs.
2Reliability
If the printing device requires users to allocate priority levels to all font designs, then complete control is achieved, but the operation becomes difficult when the number of font designs increases
Solution Approach 1:
The patent divides the font design management into two operational modes: simple priority level change for individual font designs and comprehensive priority level allocation for all font designs. This segmentation maintains reliable control over font design selection while significantly easing the operation burden on users.
Solution Approach 2:
The system provides self-service functionality by automatically managing the priority level allocation process. When users input the name of a font design and its desired priority level, the system automatically processes the change without requiring users to manually manage all other font designs, thereby maintaining control accuracy while improving ease of operation.
3Adaptability or versatility
If the printing device allocates priority levels to all font designs at once, then comprehensive control is possible, but the user needs to grasp types of font designs available in the printing device
Solution Approach 1:
The patent enables users to perform partial priority level changes by inputting only the name of the specific font design they wish to modify and its new priority level. This partial action approach maintains the versatility of font design selection while eliminating the need for users to have comprehensive knowledge of all available font designs.
Solution Approach 2:
The system acts as an intermediary by accepting simple commands from users containing only the target font design name and desired priority level. The system then handles the complex task of updating the priority level allocation internally, mediating between the user's simple input and the complex internal data structures.
4Measurement precision
If the printing device requires complete knowledge of all font designs for priority level allocation, then accurate control is achieved, but it becomes difficult to readily change the priority level of a desired font design
Solution Approach 1:
The patent segments the priority level control into a simple operation mode where users can precisely control the priority level of a specific font design by inputting only its name and desired priority level. This segmentation maintains measurement precision for priority level control while dramatically improving ease of operation.
Solution Approach 2:
The system provides self-service functionality that automatically identifies and updates the priority level of the specified font design without requiring users to have comprehensive knowledge of all font designs. The system handles the precise control internally while providing a simple user interface.

AI summary
A printing device includes: a printing unit performing printing; and a control unit that, when accepting a character code associated with a plurality of font designs, causes the printing unit to print a character indicated by the character code, based on a priority level allocated to each of the plurality of font designs. The control unit changes the priority level of the plurality of font designs in response to a first command that is accepted. The first command is a command indicating the priority level of the font design that is a part of the plurality of font designs.
