Printing Apparatus Display Controller Segmentation for Continuous Copy Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing apparatuses lack efficient display of progress information during continuous printing of the same data multiple times, requiring users to expend time and effort to find relevant information, as the displayed information remains the same regardless of the copy being printed.
Innovation Solution
A printing apparatus with a display controller that shows a first screen including the image to be printed before completing the first copy and a second screen indicating the printing apparatus's state without the image after the first copy is completed but before all copies are finished, allowing users to confirm the image and apparatus state separately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display shows the same information throughout the printing process, then all information is consistently available, but users must spend time and effort to search for useful information
Solution Approach 1:
The display information is segmented into different stages: before first copy printing and during subsequent copies printing. The controller selectively displays the image to be printed only during the first copy printing stage, while displaying other useful information during subsequent stages. This segmentation resolves the contradiction by making information accessible when needed without requiring continuous search.
Solution Approach 2:
The display content dynamically changes based on the printing stage. The controller adjusts what information is displayed according to whether the first copy is being printed or subsequent copies are being printed. This dynamic adaptation eliminates the need for users to search through static, unchanged display information.
2Loss of information
If the display shows the image to be printed throughout the entire printing process, then users can continuously confirm the printing content, but the display occupies space and may show unnecessary information during later stages
Solution Approach 1:
The display is segmented into different functional stages: the image to be printed is displayed only during the first copy printing stage when verification is most needed. During subsequent copies printing, the display transitions to showing other useful information such as printing status or apparatus state. This resolves the contradiction by optimizing display content for each specific stage rather than showing all information continuously.
Solution Approach 2:
Instead of showing the image to be printed throughout the entire printing process (excessive action), the system shows it only during the first copy printing stage (partial action). This partial display approach is sufficient for verifying printing content while freeing up display space and reducing unnecessary information during subsequent stages, thereby improving display efficiency.

AI summary
A printing apparatus includes a display controller that causes a display unit to execute displaying, and a printing unit that executes printing based on a print job. When a plurality of copies are to be printed based on the print job, the display controller causes the display unit to display a first screen including an image to be printed before completion of the printing of a first copy and causes the display unit to display a second screen that does not include the image to be printed and includes information indicating a state of the printing apparatus after the completion of the printing of the first copy and before completion of the printing of all of the copies.
