Print Data List Status Display for Incomplete Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In pull-print systems, users face delays in displaying print data lists on printing apparatuses due to incomplete reception processing of print data, preventing immediate printing instructions for large or high-volume print jobs, and requiring users to wait until data is fully received before displaying options.
Innovation Solution
A server apparatus and printing apparatus system that allows for the transmission and display of print data lists, including status updates on data that has not yet been fully received, enabling users to provide printing instructions even before complete data reception by including identification information for both completed and in-progress data transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits for complete reception processing of print data before displaying the print data list, then the reliability of data completeness is improved, but the user wait time and operational efficiency deteriorate
Solution Approach 1:
The server generates and transmits the print data list to the printing apparatus in advance, before the print data reception is completely finished. The list includes identification information for both completed and in-progress data transfers, allowing the user to see and select from available print jobs immediately rather than waiting for complete data reception.
Solution Approach 2:
The system provides feedback to the user about the reception status of print data through status indicators in the print data list. The printing apparatus displays whether each print data's reception is completed or in progress, giving the user real-time information about data availability while enabling premature selection and printing of completed items.
2Measurement precision
If the system requires complete data reception before displaying print options, then the accuracy of bibliographic information is improved, but the productivity and operational speed deteriorate
Solution Approach 1:
The server performs preliminary processing to extract and transmit bibliographic information (such as document name, number of pages, and other metadata) as soon as it becomes available, even before the complete print data reception is finished. This allows the printing apparatus to display accurate bibliographic information immediately for user selection.
3Reliability
If the system waits for complete print data reception before allowing printing instructions, then the reliability of print job integrity is improved, but the ease of operation and user convenience deteriorate
Solution Approach 1:
The system provides real-time feedback to the user about which print data receptions are completed and ready for printing. The printing apparatus displays status information for each print job in the list, clearly indicating which items can be immediately printed versus those still being received, allowing users to conveniently select and print from available jobs without waiting for complete system synchronization.
Data Source
AI summary
A server apparatus includes a first receiving unit configured to receive print data transmitted from a client apparatus, a storage unit configured to store the print data of which reception has finished by the first receiving unit, and a second receiving unit configured to receive, from a printing apparatus, a request of print data, and a transmission unit configured to, in response to the request received by the second receiving unit, transmit a list of print data to the printing apparatus, the list of print data including identification information of the print data stored in the storage unit and identification information of print data of which reception has been started but has not finished by the first reception unit yet.
