label printing mix up

Hi everyone,

We face an issue where by our Zebra printer (ZT230) print label from other order. Let me walk through the scenario.

Order A pack into 5 parcels which require 5 labels.

Printer ZZZ print total 5 labels. But one (out of 5 labels), is for order B.

We checked the payload details on label request for both orders. Order A label request point to printer ZZZ. Whilst, Order B label request point to printer XXX. Both different printers. Why this happen? Anyone has experience this before?

Printer ZZZ and XXX is ZT230 model type.
