Printer Memory Management via External Data Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing apparatuses, such as printers, face challenges in managing memory space, especially in POD systems where memory boxes fill up quickly, leading to inefficiencies in image data storage and retrieval, and limitations in devices without large capacity hard disks.
Innovation Solution
A data processing apparatus with a memory unit that allows users to transmit and manage image data to an external apparatus, enabling flexible data processing and storage through a user interface, allowing selection, transfer, and processing of image data, even in devices without large capacity hard disks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image data is transferred to an external computer and erased from the memory box, then free storage space is recovered, but it becomes necessary to re-transmit image data back to the memory box for printing operations
Solution Approach 1:
The system performs preliminary actions by maintaining link destination information and enabling automatic re-acquisition of image data when needed. Instead of requiring manual re-transmission, the printer automatically retrieves data from the external storage location when a print operation is requested, saving user time and effort.
Solution Approach 2:
The invention introduces link destination information as an intermediary element that bridges the memory box and external storage. This intermediary allows the system to track and automatically re-acquire image data without requiring manual user intervention, effectively mediating between the erased data and the need for printing.
2Productivity
If image data is kept in the memory box for immediate printing operations, then printing can be performed immediately, but the memory box will eventually become full and unable to store new image data
Solution Approach 1:
The system extracts image data from the memory box to external storage while maintaining the ability to quickly retrieve it when needed. This extraction allows the memory box to be reused for new image data while preserving access to previously stored images through the external storage link.
Solution Approach 2:
The system dynamically manages storage by allowing image data to move between the memory box and external storage based on needs. The link destination information enables flexible re-acquisition of data, making the storage system dynamic rather than static, adapting to both immediate printing needs and long-term storage requirements.
3Quantity of substance
If a printer is equipped with a large capacity hard disk to provide memory box function, then sufficient storage space is available, but devices without large capacity hard disks cannot provide memory box function
Solution Approach 1:
The invention makes the memory box function universal by enabling printers without large capacity hard disks to provide memory box functionality. By using external storage devices and maintaining link destination information, any printer can offer image data storage and retrieval capabilities regardless of its internal storage capacity.
Solution Approach 2:
The link destination information acts as an intermediary that allows printers with limited internal storage to access external storage resources. This intermediary mechanism enables small printers to function as if they have large internal storage by bridging to external storage devices through network or direct connections.

AI summary
A data processing apparatus that can flexibly deal with various needs of a user while effectively utilizing a memory unit thereof that can store a plurality of data. The data processing apparatus, which is equipped with a memory unit capable of storing data, executes processing of transmitting the data of the memory unit to an external apparatus and erasing the data of the object of transmission to the external apparatus from the memory unit. An acceptance of a specific user request related to processing of the data transmitted to the external apparatus is allowed in a case where the data has been transmitted to the external apparatus. The data processing apparatus executes processing using the data transmitted to the external apparatus in a case where the acceptance of the specific user request is performed via the user interface unit.
