Printing Apparatus Sheet Type Information Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IPP-based printing systems face challenges in displaying sheet type information accurately, particularly when dealing with vendor extension sheet types and IPP standard sheet types, leading to user confusion due to duplicate displays.
Innovation Solution
A printing apparatus that transmits and receives information based on established rules, including a reception unit to receive the display mode of sheet types from an information processing apparatus and a determination unit to determine the sheet type information to be transmitted, ensuring only necessary sheet type information is displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vendor extension sheet types and IPP standard sheet types are both transmitted from the printing apparatus, then the completeness of sheet type information is improved, but user confusion occurs due to duplicate displays
Solution Approach 1:
The patent extracts and removes duplicate sheet type information from the transmission data. The determination unit identifies and eliminates redundant vendor extension sheet types that would otherwise be displayed alongside IPP standard sheet types, ensuring only necessary unique information is transmitted to the information processing apparatus.
Solution Approach 2:
The patent changes the parameter of sheet type information transmission by dynamically determining which sheet types to transmit based on the display mode received from the information processing apparatus. This parameter change allows the system to adapt between transmitting comprehensive information or filtered information without duplicates.
2Loss of information
If the printing apparatus transmits all sheet type information without filtering, then information completeness is improved, but the complexity of information processing increases
Solution Approach 1:
The patent applies preliminary action by performing determination and filtering of sheet type information before transmission. The determination unit pre-processes the sheet type data based on the received display mode, eliminating duplicates in advance, which simplifies the information processing load on both the printing apparatus and the information processing apparatus.
3Adaptability or versatility
If the printing apparatus adapts to different display modes from various information processing apparatuses, then adaptability is improved, but the complexity of determining transmitted information increases
Solution Approach 1:
The patent implements dynamics by making the sheet type transmission adaptive and flexible based on the received display mode. The determination unit dynamically adjusts which sheet types are transmitted according to the specific display mode from the information processing apparatus, enabling compatibility with different systems while maintaining a relatively simple determination logic through clear conditional rules.

AI summary
A printing apparatus includes a reception unit and a determination unit. The reception unit receives a display mode of a sheet type from an information processing apparatus. The determination unit determines sheet type information to be transmitted to the information processing apparatus, based on the display mode of the sheep type received by the reception unit.
