Printer Download Printing Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers lack flexibility in selecting print modes for download printing, typically determining the mode based on their design rather than user preferences or document characteristics.
Innovation Solution
A printer system that includes a controller to acquire and analyze instruction data containing mode information, allowing it to perform download printing in either a separate mode, where printing starts after the entire document is received, or a parallel mode, where printing begins before the document is fully received, enabling user-specified print modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printer determines print mode based on its own design, then the printing process is simple and reliable, but the adaptability to user preferences and document characteristics is poor
Solution Approach 1:
The printer automatically acquires and analyzes instruction data containing mode information from the transmission source, and autonomously determines the print mode (separate mode or parallel mode) based on this information without requiring manual user configuration. The controller executes the determined print mode automatically, making the system self-adaptive to user preferences and document characteristics while maintaining operational simplicity.
2Productivity
If the printer waits to receive the entire document before printing, then printing accuracy is ensured, but the printing speed decreases
Solution Approach 1:
The printer dynamically selects between two printing approaches based on mode information: in separate mode, the entire document is received before printing to ensure completeness; in parallel mode, printing starts before the entire document is received to improve speed. This dynamic adaptation allows the system to optimize between speed and reliability depending on the specific printing requirements.
Solution Approach 2:
The print mode parameter is changed based on the acquired mode information from instruction data. The controller adjusts the printing process parameters (whether to wait for complete document reception or start printing prematurely) according to the specified mode, enabling flexible control over the trade-off between printing speed and document completeness.
3Loss of time
If the printer starts printing before receiving the entire document, then printing speed increases, but the risk of incomplete or erroneous printing increases
Solution Approach 1:
In parallel mode, the printer performs preliminary printing actions before the entire document is received, starting the printing process with the portion of the document already available. This preliminary action reduces the total time loss by overlapping document reception and printing operations, while the system continues to monitor for complete document reception to ensure printing accuracy.
Data Source
AI summary
Instruction data is configured to include mode information indicating a print mode in download printing. The print mode includes a first mode and a second mode different from the first mode. The download printing includes: in response to extracting the mode information indicating the first mode, performing the download printing by the first mode, the first mode being a mode of, after completing reception of an entirety of a document, starting printing based on the entirety of the document; and in response to extracting the mode information indicating the second mode, performing the download printing by the second mode, the second mode being a mode of, before completing reception of the entirety of the document, starting printing based on a received portion of the document. The second mode is a mode in which reception of the document and printing based on the document are performed in parallel.
