Print Control Device for Adaptive Print Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print cancel control systems in print apparatuses do not allow users to select appropriate print cancel activities based on specific print conditions, such as types of applications and printed sheets, leading to difficulties in interrupting the print process effectively.
Innovation Solution
A print control device that acquires print conditions and allows users to input a print stop instruction, deciding the appropriate stage to stop the print based on these conditions, enabling the print apparatus to cancel the process accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed print cancel activities are provided on the operation section, then the device complexity is reduced, but the adaptability to different print conditions deteriorates
Solution Approach 1:
The print control device automatically determines the appropriate print cancel activity by itself based on the current print condition (photo print or document print), without requiring the user to manually select from multiple options. This self-service approach resolves the contradiction by eliminating the need for complex user interfaces while maintaining high adaptability to different print conditions.
2Ease of operation
If automatic print cancel control based on print condition is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The system performs preliminary classification of the print condition (photo print or document print) before the print cancel operation occurs. This preliminary action allows the control logic to be simple and straightforward, as it only needs to check the pre-determined print condition type and execute the corresponding cancel activity, rather than handling complex real-time decisions during print cancellation.

AI summary
When a print stop instruction is input in accordance with a user's operation, a stage to stop print is decided among a plurality of stages in accordance with the print condition for print and the print by the print apparatus is stopped at the decided stage. Thereby, print by the print apparatus can be canceled appropriately.
