Printing Apparatus CSR Display Segmentation for Cloud Print Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The usability of user interfaces for printing apparatuses registered with cloud print services is impaired by the undesired display of certificate signing requests (CSRs), which can confuse users attempting to register certificates for purposes other than cloud printing, increasing user effort and time.
Innovation Solution
The printing apparatus is configured with a communication unit, display unit, and transmission unit to manage CSRs and certificates, allowing only relevant CSRs and certificates for cloud print services to be displayed, thereby improving user interface usability by hiding or gray-out CSRs and certificates intended for cloud print services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all CSRs and certificates are displayed on the user interface, then users can access all certificate information, but users are confused and experience increased effort and time when trying to find specific certificates
Solution Approach 1:
The patent segments certificate information into two distinct categories: cloud print service certificates and other certificates. The display unit selectively displays only cloud print service certificates to users, while non-cloud certificates are stored separately in the storage unit without being displayed. This segmentation resolves the contradiction by organizing information hierarchically, ensuring users can easily access cloud print certificates without being overwhelmed by unrelated certificate information, while still maintaining the ability to access other certificates through a separate registration process.
2Adaptability or versatility
If cloud print service certificates are displayed alongside other certificates, then users can manage all certificates in one place, but users may accidentally delete or misuse cloud print certificates
Solution Approach 1:
The patent extracts cloud print service certificates from the general certificate management interface and creates a separate display pathway. The display unit is configured to show only cloud print service certificates on the main user interface, while other certificates are excluded from this view. This extraction protects cloud print certificates from accidental deletion or misuse by isolating them in a dedicated display area, while still allowing users to register and manage other certificates through a separate process that does not interfere with cloud print functionality.
3Productivity
If the printing apparatus automatically transmits registration requests with CSRs, then the registration process is streamlined, but users lose visibility and control over the CSR transmission
Solution Approach 1:
The patent implements preliminary action by having the display unit show cloud print service certificates and their associated CSRs to users before the automatic transmission occurs. The transmission unit is configured to automatically transmit registration requests to the print service, but the display unit ensures that users have previously viewed and acknowledged the CSR information that will be transmitted. This preliminary display action maintains user awareness and control over the automatic transmission process, resolving the contradiction between streamlined automation and user visibility.

AI summary
A printing apparatus includes a transmission unit configured to transmit a request to register the printing apparatus and a signing request necessary to issue a certificate of the printing apparatus to a system upon receiving a registration instruction for registering the printing apparatus with a print service from a user. A display unit refrains from displaying third display information for identifying the signing request transmitted by the transmission unit.
