Printer Data Filtering for POS Transmission Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers in retail systems transmit unnecessary information during printing operations, leading to inefficiencies and reduced processing efficiency in data analysis and management.
Innovation Solution
A printer and control method that discriminates and masks personal information and unnecessary data formats before transmitting print text data to a control server, using transmission discrimination and information specification formats to ensure only relevant data is processed, thereby preventing unnecessary data transmission and maintaining processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the printer transmits all print text data to the control server, then complete information is available for analysis, but unnecessary data transmission increases processing load and reduces efficiency
Solution Approach 1:
The patent extracts and removes unnecessary information from the print text data before transmission. The controller identifies and eliminates redundant data elements such as formatting commands, control instructions, and non-essential text content, transmitting only the necessary information to the control server. This extraction process maintains data completeness for analysis while reducing transmission volume and processing load.
Solution Approach 2:
The patent segments the print text data into distinct components: essential information requiring transmission and non-essential information to be discarded. By dividing the data stream into meaningful segments and selectively transmitting only the relevant portions, the system optimizes the balance between information completeness and processing efficiency.
2Measurement precision
If the printer transmits detailed print text data, then comprehensive analysis is possible, but data transmission volume and processing time increase
Solution Approach 1:
The patent extracts only the essential information elements required for accurate analysis from the complete print text data. By removing redundant formatting data, control commands, and non-essential content, the system maintains measurement precision for critical parameters while significantly reducing the time required for data transmission and processing.
3Loss of information
If the printer transmits all received data, then no information is lost, but unnecessary information consumes bandwidth and processing resources
Solution Approach 1:
The patent extracts and removes unnecessary data elements from the print text before transmission, identifying and eliminating redundant information such as formatting commands, control instructions, and non-essential content. This extraction process maintains the completeness of essential information while reducing bandwidth consumption and processing resource usage.
Solution Approach 2:
The patent discards non-essential information from the print text data while preserving critical information elements. The controller selectively discards redundant data that does not contribute to the core analysis objectives, thereby conserving energy and processing resources without compromising the integrity of essential information.

AI summary
There is provided a printer including: a storage that stores transmission discrimination format information and information specification format information; a printing executor that performs printing based on print data received from a POS terminal; and a controller that transmits print text data, in which information adapted to information specification format indicated by information specification format information among information included in the print text data is converted or deleted, to a control server when a format of the print text data based on the print data received from the POS terminal is adapted to a transmission discrimination format indicated by the transmission discrimination format information.
