Solution Overview
Problem
Existing printer searching systems are inefficient in identifying nearby printers, as they rely on manual registration of printer addresses and may not accurately determine proximity based on IP addresses.

A printer searching device and method that utilizes global and private IP address matching to identify nearby printers by comparing network address parts, enhancing the likelihood of finding printers in vicinity through advanced IP address analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual registration of printer addresses is used, then system implementation is simple, but search accuracy and automation are poor
Solution Approach 1:
The system enables printers to automatically register themselves with the search server using their global IP addresses without requiring manual administrator intervention. The printer searching device autonomously performs IP address analysis and proximity determination, eliminating manual input while maintaining system simplicity through automated self-service mechanisms.
Solution Approach 2:
The patent replaces manual mechanical registration processes with automated electronic IP address-based search mechanisms. By substituting manual address input with automated global IP address analysis, the system achieves higher search accuracy while reducing operational complexity through electronic automation rather than mechanical manual procedures.
2Productivity
If IP address matching is used to determine printer proximity, then search automation improves, but accuracy may be insufficient without advanced analysis
Solution Approach 1:
The patent segments the IP address into multiple components (global IP address, network address part, host address part) and performs hierarchical matching. By dividing the IP address analysis into segments, the system can efficiently automate the search process while maintaining high accuracy through multi-level comparison of network and host portions.
Solution Approach 2:
The patent adds dimensional depth to IP address matching by comparing both network address parts and host address parts separately. This multi-dimensional approach enhances search efficiency through automated hierarchical matching while improving accuracy by analyzing multiple address components rather than treating the IP address as a single undifferentiated value.
3Measurement precision
If entire global IP address matching is performed, then proximity determination accuracy increases, but search scope and adaptability decrease
Solution Approach 1:
The patent implements dynamic matching criteria that can adapt between partial network address matching and entire IP address matching based on search requirements. The system dynamically adjusts the scope of IP address comparison, allowing flexible switching between broad network-level searches and precise host-level matching, thereby maintaining both accuracy and adaptability.
Solution Approach 2:
The patent changes the matching parameter from fixed entire IP address comparison to variable partial IP address comparison. By allowing the matching scope to be adjusted between network address part only, host address part only, or entire IP address, the system achieves high precision when needed while maintaining search flexibility and adaptability through parameter variation.
