Cloud Print Driver Conflict Detection via Constraint Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud print services do not effectively determine conflicts between print settings and constraints, leading to potential issues with print jobs, as they lack the capability to assess whether a combination of setting values violates constraints specific to printers.
Innovation Solution
An information processing apparatus is developed with a display unit, reception unit, and determination unit that displays a print setting screen, receives user instructions, and determines conflicts based on constraint information from an external apparatus, ensuring that print settings do not violate printer-specific constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driver for cloud print service is used that is compatible with printers of multiple types, then adaptability is improved, but the driver cannot determine whether current print settings include values matching constraints, leading to potential conflicts
Solution Approach 1:
The patent introduces a constraint information acquisition unit as an intermediary component between the cloud print service driver and the print settings. This unit acquires constraint information from the cloud print service and provides it to the determination unit, which then checks for conflicts. This intermediary mechanism enables the system to maintain broad driver compatibility while adding reliable constraint checking capability.
Solution Approach 2:
The patent implements preliminary action by acquiring constraint information from the cloud print service before generating the print job. The determination unit checks whether the print settings include values that match the constraints in advance, and only if no conflicts are found does the system proceed to generate the print job. This preliminary validation prevents conflicting settings from being transmitted to the printer.
2Ease of operation
If print settings are generated without checking constraints, then ease of operation is improved, but print errors occur due to conflicting settings
Solution Approach 1:
The patent implements self-service by having the determination unit automatically check constraint compliance without requiring user intervention. The system autonomously acquires constraint information, compares it with the print settings, and determines conflicts automatically. This maintains ease of operation for users while ensuring reliability through automated validation.
Solution Approach 2:
The patent incorporates feedback by having the determination unit provide information about constraint conflicts back to the user. When conflicts are detected, the system can notify the user and prevent the print job from being generated, or automatically adjust settings. This feedback mechanism maintains operational simplicity while ensuring print job validity through automated constraint checking.
3Reliability
If constraint checking is added to the print process, then print setting reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the determination unit and constraint information acquisition unit to work with multiple printer types and cloud print services through a unified approach. The constraint information acquisition unit can obtain constraints from various cloud print services, and the determination unit can check constraints for different printer models, making the added complexity applicable across the board rather than requiring separate solutions for each printer type.
Solution Approach 2:
The patent segments the constraint checking function into separate modular components: a constraint information acquisition unit that retrieves constraints from the cloud print service, and a determination unit that performs the actual conflict detection. This segmentation allows the reliability-enhancing functionality to be added as discrete, manageable modules rather than integrating it throughout the entire print system, thereby controlling overall device complexity.

AI summary
An information processing apparatus that transmits print data to a server in which information regarding an image forming apparatus is registered in accordance with a registration request from the image forming apparatus, and includes an installed application that sets a setting value included in the print data, the information processing apparatus includes a display unit configured to display a print setting screen provided by the application, a reception unit configured to receive an instruction to set a setting value of a setting item, via the print setting screen, and a determination unit configured to determine whether a conflict occurs between the setting value of the setting item set in accordance with the received instruction and a setting value of a different setting item, based on constraint information acquired from an external apparatus.
