Printer Driver Installer Feedback for WPP Restriction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in installing vendor drivers due to OS restrictions, particularly with Windows Protected Print Mode (WPP) enabling or disabling vendor printer drivers without user intent, making it challenging to identify the cause of installation failures.
Innovation Solution
A program is provided on a non-transitory computer readable storage medium that allows users to install specific software and display notifications regarding OS restrictions, enabling users to change settings and install vendor drivers even when WPP is enabled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WPP is enabled to restrict vendor driver installation for security reasons, then system security is improved, but user ability to install vendor drivers deteriorates
Solution Approach 1:
The installer includes a notification unit that detects when WPP is enabled and provides feedback to the user by displaying a notification message explaining the installation failure cause. This feedback mechanism informs users that the restriction is due to WPP settings, not a system error, enabling them to understand and adjust settings accordingly.
Solution Approach 2:
The notification message acts as an intermediary between the WPP restriction mechanism and the user. Instead of directly blocking installation without explanation, the notification mediates by providing contextual information about why the installation failed and what the user can do to proceed, bridging the gap between security restrictions and user needs.
2Adaptability or versatility
If WPP setting is changed to enabled state to restrict vendor drivers, then driver installation control is improved, but user awareness of restriction cause deteriorates
Solution Approach 1:
The notification unit provides feedback information to users when WPP is enabled, displaying a message that explicitly states the installation failure is caused by WPP settings. This prevents information loss by ensuring users understand the restriction cause rather than encountering a generic error message.
3Reliability
If OS updates automatically enable WPP to enforce print mode restrictions, then print mode security is improved, but installation failure detection ability deteriorates
Solution Approach 1:
The notification mechanism provides immediate feedback to users when WPP-enabled OS updates prevent vendor driver installation. By displaying a specific notification message rather than a generic error, the system makes the cause of installation failure easily detectable and understandable.
Solution Approach 2:
The notification message serves as an intermediary that translates the technical WPP restriction into user-understandable information, bridging the gap between automated OS security updates and user comprehension of installation failure causes.

AI summary
A non-transitory computer readable storage medium in the present disclosure stores a program for installing, in an information processing apparatus, specific software for providing a print function different from that by OS having a function of setting whether to enable a specific print mode as OS's function, and a function of restricting specific software installation in a case where the specific print mode is set to be enabled, the program causing a computer to function to install the specific software in a case where an operation for specific software installation is performed by a user and the specific print mode is set to be disabled, and function to display a specific notification on a restriction on the specific software in a case where the operation for installing the specific software is performed by a user and the specific print mode is set to be enabled.
