Printer Device Display Control Integration for POS Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing POS system suffers from inefficiencies in payment processing due to independent control of printer and display devices by the processor, leading to increased processing time and reduced throughput.
Innovation Solution
A printer device that includes a display information generation module, a detector, and a printing controller to convert instruction information using an association table, allowing it to determine whether to output printing information based on detected instructions, thereby reducing the need for independent output to both the printer and display devices, optimizing communication and processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the processor controls the printer device and display device independently of each other, then each device can be controlled separately, but the processing efficiency of the processor deteriorates
Solution Approach 1:
The patent merges the control functions of the printer device and display device into a single integrated control system. The printer device now generates control signals for both the printer mechanism and the display device, eliminating the need for the processor to independently control both devices. This integration reduces the processor's workload and improves payment processing efficiency while maintaining the ability to control both devices separately through the unified control architecture.
2Reliability
If the processor outputs information to both printer device and display device independently, then both devices receive their required information, but the amount of information transmission increases
Solution Approach 1:
The patent extracts the display control function from the processor and relocates it to the printer device. The printer device now generates display control signals based on the print data, eliminating the need for the processor to separately transmit information to the display device. This extraction reduces communication overhead while ensuring the display device receives the necessary information through the printer device's generated signals.
3Productivity
If the printer device generates display control signals based on print data, then processing efficiency improves, but the printer device's functionality increases
Solution Approach 1:
The patent implements multi-functionality in the printer device by enabling it to perform both printing and display control functions. The printer device generates control signals that can drive various types of display devices (LCD, LED, OLED, etc.), making it a universal control unit. This approach improves processing efficiency by consolidating control functions while the printer device's enhanced functionality is justified by the overall system simplification and performance improvement.
