To make sure if your cash drawer is properly connected to a printer, the best way to test it is by opening the drawer from the printer preferences:
- Open the Bizzon application menu by tapping the (≡) icon,
- select Settings,
- go to Devices -> Printers,
- in the right window, tap the printer in the list of connected printers to enter its settings,
- tap the OPEN CASH DRAWER button.
