Print Control Apparatus Preventing Data-Exhaust Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing operations are often interrupted due to data-exhaust, where the receiving rate of data is lower than the printing rate, leading to wasteful consumption of consumables and inefficiencies, as existing solutions do not adequately manage the start of printing based on the total data amount.
Innovation Solution
A control apparatus with a reception unit, setting unit, image processing unit, print control unit, determination unit, and change unit that determines whether all image data has been received before completing printing, and adjusts the operation mode to prevent premature start of printing even if print data generation is complete, based on the determination result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If printing operation starts when a predetermined amount of data is received regardless of total data amount, then printing can begin earlier improving productivity, but data-exhaust may occur during printing causing interruptions and waste
Solution Approach 1:
The determination unit performs preliminary assessment of the total data amount before starting printing. By evaluating whether the received data amount exceeds a predetermined threshold that would cause data-exhaust during printing, the system prepares appropriately in advance. This preliminary action prevents interruptions by ensuring sufficient data is available for the entire printing operation.
Solution Approach 2:
The system continuously monitors the relationship between received data amount and total data amount during printing operation. Based on this feedback, the control unit can dynamically adjust printing operations to prevent data-exhaust. The feedback mechanism ensures reliable continuous operation by responding to real-time data availability status.
2Productivity
If printing starts immediately when print data is generated, then printing efficiency is improved, but consumables are wasted due to interruptions from data-exhaust
Solution Approach 1:
Before initiating printing, the determination unit performs a preliminary check to verify that the received data amount is sufficient to complete the printing operation without data-exhaust. This preliminary action prevents wasteful consumption of consumables by avoiding printing operations that would inevitably be interrupted, thereby maintaining high printing efficiency without substance loss.
3Adaptability or versatility
If printing operation is interrupted due to data-exhaust, then data receiving can be resumed, but recovery processing is required causing time loss and consumable waste
Solution Approach 1:
The control unit continuously monitors data reception status and printing progress, using this feedback to determine when to start printing. By ensuring the received data amount exceeds the threshold before initiating printing, the system prevents data-exhaust interruptions, eliminating the need for time-consuming recovery processing while maintaining flexible data receiving capabilities.

AI summary
A control apparatus, comprising a reception unit configured to receive image data, a setting unit configured to set an operation mode, an image processing unit configured to generate print data based on the image data, a print control unit configured to cause a printing unit to perform printing on a printing medium based on the print data, a determination unit configured to determine whether reception of all the image data is complete before the printing unit completes predetermined printing, and a change unit configured to change the set operation mode to another operation mode in a case where the set operation mode is an operation mode in which printing based on the print data starts if the image processing unit generates the print data.
