Solution Overview

Problem

Users face decreased user-friendliness and increased operation load when inputting print jobs via wireless direct communication in printing apparatuses with active reservation printing settings, as they need to manually initiate print processing after searching for reserved jobs on the console.

Innovation Solution

The printing apparatus automatically performs print processing for jobs received via wireless direct communication, even with reservation settings active, eliminating the need for users to manually initiate print jobs from the console, by determining the source interface of the print job and skipping reservation processing when the job is received through the wireless direct interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If reservation printing is activated to store print jobs without processing until user instruction, then print jobs are prevented from being forgotten and processing is assured only when user is present, but user operation load increases and user-friendliness decreases when jobs are received via wireless direct communication

Engineering Contradiction:
Improveassurance of user presence for print processingVSAvoiduser operation load
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the treatment of print jobs based on their input interface. Jobs received via wireless direct communication are processed immediately without reservation, while jobs from other interfaces continue to follow the reservation printing流程. This localized differentiation resolves the contradiction by adapting the reservation behavior to the specific communication channel, eliminating unnecessary operations for wireless direct jobs while maintaining reliability for other interfaces.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent inverts the conventional reservation printing logic by making an exception for wireless direct communication. Instead of universally applying reservation printing to all interfaces, the system inverts the approach by automatically processing wireless direct jobs without reservation, even when reservation printing is activated. This inversion resolves the contradiction by reversing the normal behavior for specific cases where user presence is already assured through the wireless direct connection establishment process.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If reservation printing is activated to store print jobs in storage area without processing, then print processing is performed only when user instruction is given, but unnecessary reservation steps are required for wireless direct communication jobs

Engineering Contradiction:
Improvecontrolled print processingVSAvoidprocessing flow complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by implementing interface-specific processing rules within the print job handling system. The determination unit identifies the input interface and applies different processing paths: wireless direct communication jobs bypass the reservation storage step and proceed directly to processing, while other interfaces follow the conventional reservation流程. This localized differentiation reduces processing flow complexity for wireless direct jobs while maintaining controlled print processing through the reservation mechanism for other interfaces.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent extracts the reservation processing step from the overall print job handling flow for wireless direct communication jobs. By separating the processing path for wireless direct jobs from the conventional reservation printing流程, the system removes the unnecessary reservation storage and retrieval steps for these specific jobs. This extraction simplifies the processing flow by eliminating redundant operations while preserving the controlled print processing capability for jobs from other interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If print jobs via wireless direct communication are reserved like other jobs, then consistent reservation printing behavior is maintained, but user-friendliness is degraded and operation load increases

Engineering Contradiction:
Improveconsistent reservation printing behaviorVSAvoiduser-friendliness
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent applies local quality by creating an exception rule for wireless direct communication jobs within the reservation printing system. The determination unit identifies jobs from wireless direct interface and applies a different processing rule (immediate processing without reservation) compared to jobs from other interfaces. This localized differentiation maintains stability and consistency for the majority of jobs while improving user-friendliness for wireless direct communication by eliminating unnecessary reservation steps.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces dynamic behavior to the reservation printing system by making the processing path adaptable based on the input interface. The system dynamically determines whether to apply reservation printing based on the communication interface used, rather than following a static, uniform rule for all jobs. This dynamic approach resolves the contradiction by allowing the system to maintain consistent reservation behavior for traditional interfaces while providing streamlined immediate processing for wireless direct communication, thereby improving user-friendliness.

Inventive Principle:
Principle #15Dynamics

AI summary

A printing apparatus capable of improving user-friendliness when the user inputs a print job via wireless direct communication in a case where a setting of reservation printing is active. The printing apparatus has a wireless direct communication function and a reservation function for reserving a received print job. A setting unit sets whether or not to use the reservation function. A determination unit determines whether or not the print job received by the printing apparatus is a print job received by the wireless direct communication function. A control unit prints the received print job without reservation according to determination by the determination unit that the received print job is a print job received by the wireless direct communication function, even in a case where use of the reservation function has been set by the setting unit.
