Print Setting Conflict Detection in Printing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems fail to validate whether a print job can be executed correctly when default print settings of the printing apparatus are combined with job setting values, leading to potential printing failures even if the job is determined executable by advance validation.
Innovation Solution
A printing apparatus with a storage unit for setting information, a reception unit for print setting values, a determination unit to check for conflicts, and a notification unit to inform the communication terminal of the determination result, allowing for validation based on both job and printer settings, including prohibition conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If validation is performed based only on job setting values, then validation process is simple, but printing may fail when default printer settings conflict with job settings
Solution Approach 1:
The system performs preliminary validation by obtaining both job setting values and printer default settings before actual printing, and validates the combined settings in advance to detect potential conflicts. This preliminary action prevents printing failures by identifying incompatible setting combinations before the print job is executed.
Solution Approach 2:
The system provides feedback to the user when conflicting settings are detected during validation. The validation result includes information about incompatible setting combinations, allowing the user to modify either job settings or printer defaults before printing, thereby ensuring reliable print execution.
2Measurement precision
If default print settings are combined with job setting values for validation, then print job executability is accurately determined, but validation complexity increases
Solution Approach 1:
The system obtains printer default settings in advance and stores them for later use during validation. By preparing the default settings beforehand, the system can accurately validate combined settings without adding excessive complexity during the actual validation process.
Solution Approach 2:
The system introduces an intermediate validation process that combines job settings and printer defaults through a structured validation routine. This intermediary layer systematically compares settings against prohibition conditions, providing accurate validation results while managing complexity through organized processing steps.

AI summary
A printing apparatus is provided and stores, in a storage unit, setting formation about a print operation using the printing apparatus. The printing apparatus receives a job setting value from a communication terminal, and determines whether a prohibition condition applies to the job setting value from the communication terminal based on the received job setting value and the setting value stored in the storage unit. The printing apparatus further notifies the communication terminal of information indicating the determination result.
