Printing System Conditional Pre-Print Trigger Logic

Solution Overview

Problem

Existing printing systems unnecessarily perform pre-printing operations even when a printing operation is not executed, leading to wasteful consumption of ink and electric power.

Innovation Solution

A printing system that determines whether to initiate a pre-printing operation based on preparation instruction information, only proceeding with the pre-printing operation when specific conditions are met, and avoiding it when trigger information is present, which indicates that the actual printing operation will follow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the computer program transmits auto-wakeup command to the printer when particular conditions are satisfied, then the printer performs pre-printing operation to ensure desired quality, but the printer consumes ink and electric power wastefully when the printing operation is not actually executed

Engineering Contradiction:

Improveprinting qualityVSAvoidelectric power consumption

Core Design Contradiction:

Manufacturing precisionVSLoss of energy

Solution Approach 1:

The system performs pre-printing operation in advance when specific conditions are met (output port in ready state and particular time elapsed since last data transmission), but only when trigger information is absent. This preliminary action ensures printing quality is maintained while avoiding unnecessary operations through conditional execution based on the presence of trigger information in condition information.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If the computer program transmits auto-wakeup command to the printer when particular conditions are satisfied, then the printer performs pre-printing operation to ensure desired quality, but ink is consumed wastefully during unnecessary pre-printing operations

Engineering Contradiction:

Improveprinting qualityVSAvoidink consumption

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

The system performs pre-printing operation in advance when specific conditions are met (output port in ready state and particular time elapsed since last data transmission), but only when trigger information is absent. This preliminary action ensures printing quality is maintained while avoiding unnecessary operations through conditional execution based on the presence of trigger information in condition information.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If the printer performs pre-printing operation in advance, then the First Print Output Time is reduced, but resources are wasted when the printing operation is not executed

Engineering Contradiction:

ImproveFirst Print Output TimeVSAvoidelectric power consumption

Core Design Contradiction:

Loss of timeVSLoss of energy

Solution Approach 1:

The system performs pre-printing operation in advance when specific conditions are met (output port in ready state and particular time elapsed since last data transmission), but only when trigger information is absent. This preliminary action ensures printing quality is maintained while avoiding unnecessary operations through conditional execution based on the presence of trigger information in condition information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system checks condition information for the presence of trigger information before executing pre-printing operation. This feedback mechanism allows the system to adapt its behavior based on whether a printing operation will actually follow, preventing resource waste while maintaining the ability to perform pre-printing when beneficial.

Inventive Principle:

AI summary

A printing system includes a printer and an information processing device that includes a processor and a memory storing processor-executable instructions, the instructions being configured to, when executed by the processor, cause the processor to, when condition information does not include trigger information, determine to instruct the printer to start a pre-printing operation, when the condition information includes the trigger information, determine not to instruct the printer to start a pre-printing operation, in response to determining to instruct the printer to start the pre-printing operation, transmit the preparation instruction information to the printer, in response to determining to instruct the printer to start the pre-printing operation and performing the preparation instruction process, generate print data based on specified contents data, and transmit the print instruction information to the printer.
