LabelServer4j is a background label printing service that bridges Commander4j and physical label printer devices on a production line. When an operator assigns a Process Order to a production line, Commander4j exports a data file which LabelServer4j picks up, processes through a configurable script, and uses to drive the printer over TCP/IP.

LabelServer4j supports Zebra ZPL printers, Logopak labellers, and any device that accepts raw TCP/IP text commands. It runs as a headless background service with no graphical interface, and can manage multiple printers simultaneously in independent threads.
