Print Data Management for Seamless Monochrome Color Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Management Device Systems (MDS), users face inconvenience when switching from monochrome to color printing, requiring multiple operations between a terminal device and an image forming apparatus, leading to cumbersome processes.
Innovation Solution
An image forming system that allows users to send both monochrome and color print data to a server, which manages and stores them associated with a user ID, enabling the image forming apparatus to switch between printing modes without user intervention, allowing for seamless transitions between monochrome and color printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the user selects color printing after monochrome printing, then the printing quality is improved, but the operation complexity increases
Solution Approach 1:
The terminal device pre-prepares both monochrome and color print data before sending to the image forming apparatus. This preliminary action allows the user to switch between printing modes without needing to re-submit print jobs, thereby maintaining high printing quality while reducing operation complexity.
Solution Approach 2:
The image forming apparatus acts as an intermediary that stores multiple versions of print data (monochrome and color) and automatically retrieves the appropriate version based on user selection. This mediator function eliminates the need for users to manually re-operate the terminal device, simplifying the switching process while preserving print quality.
2Manufacturing precision
If the user switches from monochrome to color printing, then the printing quality is improved, but the time consumption increases
Solution Approach 1:
Both monochrome and color print data are prepared in advance at the terminal device before being transmitted to the image forming apparatus. This preliminary preparation eliminates the time delay that would otherwise occur if color print data needed to be generated or retrieved after monochrome printing, thus maintaining printing quality while reducing time consumption.
Solution Approach 2:
The system merges the transmission of monochrome and color print data into a single operation. By combining both print data types in one transmission cycle, the system avoids the need for separate transmission operations, thereby reducing time consumption while ensuring both printing modes maintain high quality.
3Adaptability or versatility
If the terminal device manages both monochrome and color print data, then the printing flexibility is improved, but the device complexity increases
Solution Approach 1:
The image forming apparatus serves as an intermediary storage system that holds both monochrome and color print data. This mediator role allows the terminal device to maintain printing flexibility without needing to manage complex storage and retrieval operations, as the image forming apparatus handles the complexity of storing and providing multiple print data versions.
Data Source
AI summary
An image forming system of an embodiment includes a terminal device that transmits first print data to print an image in monochrome, second print data to print the image in color and a user ID; a print data storage section that stores the first print data, the second print data and the user ID transmitted from the terminal device in an associated manner; an authentication section that authenticates a user; a list acquisition section that acquires a list including the first and second print data associated with the user ID of the user authenticated by the authentication section; a print data acquisition section that acquires one print data selected from the acquired list by the list acquisition section; and an image forming section that prints an image formed with the print data acquired by the print data acquisition section.
