Printer Ticket Completeness Verification via Scanning Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing technologies lack an effective method to accurately determine if a ticket is completely printed, leading to incomplete ticket content and potential misuse, which can result in disputes between users and publishers.
Innovation Solution
A printing control method and system that includes a printer with a scanning mechanism to verify the completeness of printed ticket data, followed by performing specific processes for complete or incomplete prints, such as marking or invalidating the ticket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the host control software sends ticket data to the printer without verification, then the printing process is simple and fast, but the ticket content may be incomplete and invalid
Solution Approach 1:
The patent implements a feedback mechanism where the printer scans the printed ticket content and sends the scanned data back to the host control software for verification. This closed-loop feedback system allows the host to confirm whether the ticket was printed completely and accurately before considering the printing successful, thereby ensuring ticket reliability without significantly impacting printing speed
Solution Approach 2:
The patent applies preliminary action by having the printer scan and prepare the printed ticket data for verification before the host control software finalizes the printing process. The scanning and data preparation happen in advance, allowing the host to quickly verify completeness without adding significant time to the overall printing workflow
2Ease of operation
If the host control software assumes printing is successful without verification, then the system operation is simple, but incomplete printing causes property loss and disputes
Solution Approach 1:
The patent implements self-service by enabling the printer to automatically scan its own printed output and prepare verification data. The printer performs the scanning and data extraction functions independently, reducing the operational burden on the host control software while ensuring ticket validity through automatic verification
3Device complexity
If no verification mechanism is implemented, then the device complexity is low, but incomplete printing cannot be detected
Solution Approach 1:
The patent introduces an intermediary scanning mechanism that acts as a mediator between the printing process and the verification process. The scanner serves as an intermediate device that captures the printed output and converts it into digital data for comparison, enabling accurate detection of printing completeness without requiring direct complex integration between the host software and printer hardware
