Printer Job Transmission Adaptation via IPP Queue Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printer management systems cannot determine whether an image forming apparatus has a queueing function when using a general-purpose printer driver, leading to issues with job transmission and order changes.
Innovation Solution
A method to control information processing apparatuses with a general-purpose driver, acquiring information on the job management apparatus's queueing function and adjusting job transmission methods accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a general-purpose printer driver is used, then compatibility with different printers is improved, but the ability to determine queueing function and manage job transmission is worsened
Solution Approach 1:
The terminal apparatus acquires information about the image forming apparatus's queueing function through IPP protocol communication, creating a feedback loop that enables the driver to adapt its job transmission behavior based on the actual capabilities of the connected printer
Solution Approach 2:
The system changes the job transmission parameters dynamically based on the acquired queueing function information, adjusting whether to transmit multiple jobs simultaneously or sequentially depending on the printer's capabilities
2Productivity
If multiple print jobs are transmitted without knowing queueing capability, then productivity is improved, but reliability is worsened due to potential job loss or incorrect processing
Solution Approach 1:
The terminal apparatus performs a preliminary check to acquire queueing function information before transmitting multiple print jobs, ensuring that the transmission strategy is predetermined based on the printer's actual capabilities
Solution Approach 2:
The system uses feedback from the image forming apparatus about its queueing capabilities to adjust the job transmission strategy, ensuring reliable processing while maintaining productivity
3Device complexity
If queueing function is not detected, then device complexity is reduced, but ease of operation is worsened due to inability to change job execution order
Solution Approach 1:
The system acquires queueing function information through IPP protocol feedback mechanisms, enabling the terminal apparatus to detect whether the image forming apparatus supports job queing without adding significant complexity
Solution Approach 2:
The job transmission and management system becomes dynamic, adapting its behavior based on the detected queueing function, allowing flexible job order management when the printer supports it
