Printing Apparatus Selective Status Information Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses are inefficient as they print all status information, wasting resources and user time, as users cannot selectively view only the desired status information.
Innovation Solution
A printing apparatus with a print controller that prints first status information and selection items, allowing users to select and print only the desired status information, reducing unnecessary printing and resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all types of status information are printed, then complete status information is provided, but user waiting time increases and print media is wasted
Solution Approach 1:
The status information is segmented into multiple categories (e.g., device status, connection status, error status) with selection items for each category. Users can select only the categories they need to view, rather than printing all status information. This segmentation allows users to obtain necessary information quickly without waiting for unnecessary data to be printed.
Solution Approach 2:
The essential status information categories are extracted and presented as selectable options. Instead of printing the entire status information set, only the selected categories are printed after user choice. This extraction principle reduces the printed content to what is actually needed, decreasing wait time and media consumption.
2Loss of information
If all types of status information are printed, then complete status information is provided, but print media consumption increases
Solution Approach 1:
Status information is divided into distinct selectable categories. Users choose which categories to print, so only relevant information consumes print media. This segmentation prevents waste of print media on unnecessary status data while ensuring complete information is available for selected categories.
Solution Approach 2:
Only the necessary status information categories are extracted for printing based on user selection. This extraction eliminates unnecessary print media consumption while maintaining completeness of the selected information types.
3Adaptability or versatility
If selection items are printed for user choice, then printing flexibility is improved, but device operation complexity increases
Solution Approach 1:
The selection interface provides localized, simple interaction for each status information category. Each selection item corresponds to a specific status category with a clear selection mechanism. This local quality approach keeps the interaction simple and intuitive at each point of selection, preventing overall system complexity from increasing significantly while maintaining high printing flexibility.

AI summary
A printing apparatus comprises: a print portion configured to perform printing on a print medium drawn from a rolled medium; and a print controller configured to cause the print portion to print status information in response to an instruction to print the status information. The print controller is configured to cause the print portion to print first status information, which is part of the status information, cause the print portion to print at least one of selection items corresponding to pieces of status information, and cause, when at least one printed selection item is selected, the print portion to print second status information corresponding to the selected selection item.
