Kickout is a Contract
Most cash drawers open via a signal from the receipt printer. If you change printer models without checking kickout compatibility, drawers fail silently at open.
What to Document
- Connector type and pinout notes from the datasheet
- Whether the drawer is printer-driven or USB/serial controlled
- Lock keying standard for the estate
Evaluation Tip
During pilot, open and close the drawer under the same POS software build used in production. Archive firmware and driver versions with the lane BOM.
See POS printers and the lane BOM guide.
