Print Setting Profile Transfer for Cloud Printing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing systems require the printing apparatus to wait for data transfer from a cloud server before setting print settings for the next job, and they face security issues due to the reporting of authentication information from portable terminal devices to printing apparatuses.
Innovation Solution
A printing system where the printing apparatus creates and transfers a print setting profile and address information to a portable terminal device, which then selects data to be printed from a cloud server using these settings, allowing the printing apparatus to print without waiting for data transfer and eliminating the need to report authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printing apparatus waits for data transfer from the cloud server before setting print settings, then the data can be printed with correct settings, but the productivity decreases due to waiting time
Solution Approach 1:
The printing apparatus creates and stores a print setting profile in advance, before receiving the print job from the cloud server. This preliminary preparation of print settings eliminates the waiting time when the actual print job arrives, as the settings are already ready to be applied immediately upon receipt of the job data.
2Adaptability or versatility
If authentication information is reported from the portable terminal device to the printing apparatus, then the printing apparatus can access the cloud server, but security problems occur
Solution Approach 1:
The authentication information is extracted and stored only in the portable terminal device, not transferred to the printing apparatus. The printing apparatus gains cloud server access capability through a different mechanism that does not involve storing or processing sensitive authentication credentials, thus maintaining security while enabling functionality.
Solution Approach 2:
The portable terminal device acts as an intermediary between the user's authentication credentials and the cloud server. It transmits only necessary print job data and settings to the printing apparatus, while retaining authentication information locally, thus mediating the access without exposing sensitive data.
3Productivity
If the print setting profile is created and transferred to the portable terminal device before printing, then the printing apparatus can operate independently, but the device complexity increases
Solution Approach 1:
The printing apparatus autonomously creates its own print setting profile based on its default settings and capabilities, without requiring external configuration. This self-service approach simplifies the overall system complexity while enabling independent operation, as the apparatus generates the necessary configuration data itself rather than relying on complex external profile management systems.
