Printing Apparatus Wireless Control via Mediator Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing apparatuses face inconvenience when receiving print data described in a page description language not supported by the device, especially when a print processing apparatus is connected, as they may directly receive unsupported data through wireless communication.
Innovation Solution
The printing apparatus is equipped with a determination unit to check for the presence of a connected print processing apparatus and a control unit to prohibit direct wireless communication functions, ensuring that print data is routed through the print processing apparatus to avoid unsupported page description languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printing apparatus enables direct wireless communication function, then the ease of operation is improved, but the reliability deteriorates due to receiving unsupported page description language
Solution Approach 1:
The patent introduces a determination unit as an intermediary component that checks whether a print processing apparatus is connected before allowing direct wireless communication. This mediator prevents unsupported page description language from reaching the printing apparatus by routing through the print processing apparatus when it is available, thus maintaining reliability while preserving ease of operation.
2Productivity
If the printing apparatus allows direct wireless communication, then the productivity is improved, but the object-affected harmful factors increase due to incompatible data formats
Solution Approach 1:
The patent applies preliminary anti-action by having the determination unit check for connected print processing apparatus before enabling direct wireless communication. This preventive measure blocks incompatible data formats from causing harm to the printing apparatus, allowing productivity improvement through direct communication while preventing harmful effects from unsupported page description languages.

AI summary
A print processing apparatus is provided such that when a print processing apparatus is connected to a printing apparatus, use of Wi-Fi Direct is prohibited. On the other hand, in the printing apparatus, when the print processing apparatus is not connected to the printing apparatus, the use of Wi-Fi Direct is permitted.
