  • Multi vendor (in one store)
    • Optional use of multiple labeling solutions in a store (sharing the same basestations)
  • Extendable
    • New fields in request or status block (for new capabilities)
  • Easy test
    • Command line sender
    • PDF can be displayed

Concept

  • Creates simple JSON file with all label it want to set
  • External process to update all labels
  • Results are stored in JSON file
