Printer Queue Driver Mismatch Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in ensuring that a printer is correctly associated with the appropriate driver when multiple drivers are installed, leading to potential mismatches and incorrect printer queue generation during USB coupling.
Innovation Solution
The device includes an acquisition unit for obtaining a printer driver, a first processing unit for installing the driver and generating a printer queue, and a second processing unit for detecting and adjusting the queue to match the installed driver, ensuring correct association and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plug and play is executed at USB coupling to automatically install printer driver and generate printer queue, then installation speed and ease of operation are improved, but printer queue may be generated with wrong driver causing functionality issues
Solution Approach 1:
The system detects the generated printer queue and compares it with the installed printer driver to identify mismatches. When a mismatch is detected, the system automatically changes the printer queue to correspond with the installed driver, ensuring proper functionality while maintaining automatic installation benefits
Solution Approach 2:
The system performs preliminary detection of printer queue and driver correspondence after installation but before actual printing operations. This preliminary check allows the system to proactively correct any driver-queue mismatches before they cause functional problems
2Adaptability or versatility
If multiple printer drivers are installed to support various printer models, then adaptability is improved, but difficulty in selecting correct driver increases
Solution Approach 1:
The system automatically performs driver selection and queue configuration without requiring user intervention. It detects the installed drivers, generates or identifies the appropriate printer queue, and ensures correspondence between the queue and the correct driver, eliminating the need for manual driver selection
Solution Approach 2:
The system introduces an intermediary detection and adjustment mechanism between driver installation and printer queue generation. This intermediary process automatically matches the correct driver with the printer queue, serving as a mediator that resolves the complexity of multiple driver options
3Loss of time
If printer queue is generated automatically during USB coupling, then installation time is reduced, but accuracy of driver-queue matching deteriorates
Solution Approach 1:
The system implements a feedback mechanism that detects the generated printer queue and verifies its correspondence with the installed printer driver. When inaccuracies are detected, the system automatically corrects the mismatch, maintaining both speed and accuracy
Data Source
AI summary
An information processing device changes a printer queue generated at the time of USB coupling with a printer to a printer queue corresponding to a predetermined printer driver, when it is detected that the generated printer queue is not a printer queue corresponding to the predetermined printer driver.
