Methods

connectBluetooth(String mac) → Future<void>
Connects to a printer via Bluetooth using the printer's mac address.
connectEthernet(String ip) → Future<void>
Connects to a printer over Ethernet using the provided ip address.
connectSerial(String port, String baudrate) → Future<void>
Connects to a printer via Serial (COM) port with a given port and baudrate.
connectUSB(String path) → Future<void>
Connects to a printer via USB using the device path.
cutPaper() → Future<void>
Sends a cut paper command to the POS printer.
disconnect() → Future<void>
Disconnects from the currently connected printer.
getPrinterStatus() → Future<String>
Requests the current printer status (int code mapped in Dart).
initializeBle() → Future<void>
isScanning() → Future<bool>
Checks whether a Bluetooth scanning process is currently active.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
