Printer Stored-Job Selection with Deferred Password Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers with storage printing functions lack efficient methods for selecting and verifying data as a print object from multiple stored data sets, particularly in scenarios involving user authentication.
Innovation Solution
A printer system that includes a user interface and controller for storing print jobs with associated verification information, allowing for user input of verification information to select and print specific job data, with processes for job extraction, password verification, and user name-based filtering to enhance operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a list of stored data is displayed and password input is required for selection, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically extracting and displaying only the job names of stored print jobs on the selection screen, without requiring password input at this stage. The password verification is performed later when the user confirms the selection or initiates printing, thus maintaining security while improving ease of operation during the selection phase
2Reliability
If password verification is required before displaying stored data, then security is improved, but productivity deteriorates
Solution Approach 1:
The system performs preliminary display of job names from stored print jobs without requiring password verification. The password check is deferred to the printing execution stage, allowing users to quickly view and select from stored jobs without authentication delays, thus improving productivity while maintaining security for actual printing operations

AI summary
A printer includes a user interface, a memory, and a controller.The controller is configured to store, in the memory, storage job data based on a print job received, to display, on the user interface, a list of the storage job data stored, and to accept a first operation and a second operation.When the controller accepts the first operation, the controller is configured to extract corresponding storage job data from the storage job data and to select a print object from the corresponding storage job data being the storage job data with which first verification information is associated and in which the first verification information corresponds to second verification information input by the first operation.When the controller accepts the second operation, the controller is configured to selecting, as the print object, the storage job data selected by the second operation.
