Printer Driver Unit for Automatic EDC Transaction Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Point of Sale (POS) systems lack a communication link between the billing system and the payment system, leading to manual input of transaction amounts, which is error-prone and prevents financial reconciliation.
Innovation Solution
A method and printer driver unit that automatically transmit data to an Electronic Data Capture (EDC) terminal by receiving a print request, extracting the final transaction amount, determining the EDC terminal's status, and generating a second print request to facilitate automatic insertion of the transaction amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of transaction amount is used in EDC terminal, then ease of operation is maintained, but reliability deteriorates due to errors
Solution Approach 1:
The printer driver unit serves as an intermediary component between the billing system and EDC terminal. It automatically transmits the final transaction amount from the billing system to the EDC terminal, eliminating manual input while maintaining system compatibility through standard printer command protocols.
Solution Approach 2:
The system enables self-service by allowing the billing system to automatically populate the transaction amount in the EDC terminal without merchant intervention. The printer driver unit handles the data transmission and integration autonomously, reducing human error and operational complexity.
2Reliability
If communication link between billing system and payment system is established, then reliability improves through automatic data transmission, but device complexity increases
Solution Approach 1:
The printer driver unit performs multiple functions: it acts as a communication bridge between billing and payment systems, formats data according to EDC terminal requirements, and handles transaction amount transmission. This multi-functionality reduces the need for separate dedicated integration components.
Solution Approach 2:
The printer driver unit serves as a universal intermediary that can interface with different billing systems and EDC terminals using standard protocols, reducing integration complexity while establishing reliable communication links between systems.
3Adaptability or versatility
If vendor-specific billing system is modified to integrate with EDC terminal, then adaptability improves, but ease of manufacture deteriorates
Solution Approach 1:
The printer driver unit acts as an intermediary that interfaces with the existing vendor-specific billing system without requiring modifications to it. It translates billing system output into EDC terminal-compatible formats, preserving the original billing system while enabling integration.
Solution Approach 2:
The integration functionality is segmented into a separate printer driver unit rather than being embedded in the billing system. This modular approach allows the billing system to remain unchanged while adding integration capability through the standalone driver component.

AI summary
The present disclosure is related to a printing driver unit, which discloses method and printer driver unit for performing a transaction by automatically transmitting data to an Electronic Data Capture (EDC) terminal. Method includes receiving, by printer driver unit associated with host computing device, first print request including first data related to purchase, from host computing device. Further, the printer driver unit extracts final transaction amount from first data and determines status of EDC terminal upon extracting final transaction amount. When EDC terminal is determined to be in first state, the printer driver unit generates a second print request including extracted final transaction amount and transmits the generated second print request to EDC terminal to facilitate automatic insertion of final transaction amount in EDC terminal to initiate payment transaction. Embodiments herein helps in auto-populating final transaction amount in EDC terminal, without the help of vendor specific billing system.
