Industrial label printing edge architecture with three-tier network segmentation: user workstations on VLAN 10, edge node infrastructure on VLAN 20 with .NET Web Application, SQLite/SQL Server queue, Print and Sync Worker Services, and BarTender REST API, connected via WAN/VPN tunnel to central Oracle Database and backend services. Data flows from workstations through Access Switch and Firewall to edge printers (A, B, C) via Printer Switch, with local queue enabling offline printing during WAN outages. Store-and-forward pattern ensures print jobs queue locally and sync when connectivity restores, critical for manufacturing environments requiring uninterrupted label production. Fork this diagram on Diagrams.so to customize VLANs, add redundancy, or adapt for your facility's printer count and database backend. Consider adding edge node failover and monitoring dashboards for production deployments.
