Print with an external printer
Use the print feature, of the BluetoothPrinter class, to print with an external printer. Access is through the MPManager object. Check how to do it.
val bluetoothPrinter = MPManager.bluetooth.printer
bluetoothPrinter.print(dataToPrint) { response ->
response
.doIfSuccess { printerResult ->
// Manage successful print case
when (printerResult) {
BluetoothPrinterResult.SUCCESS -> {
// Successful print
// ... Perform additional actions if necessary
}
BluetoothPrinterResult.NEED_SELECTION_DEVICE -> {
// More than one paired device, specific address is required
// ... Perform additional actions if necessary
}
else -> { // Other success cases }
}
}
}.doIfError { error ->
// Manage the error case if necessary
}
}
final BluetoothPrinter bluetoothPrinter = MPManager.INSTANCE.getBluetooth().getPrinter();
final Function1<MPResponse<BluetoothPrinterResult>, Unit> callback =
(final MPResponse<BluetoothPrinterResult> response) -> {
if (response.getStatus() == ResponseStatus.SUCCESS) {
// Perform additional actions if necessary
} else {
//Manage the error case if necessary
}
return Unit.INSTANCE;
};
bluetoothPrinter.print(dataToPrint, callback);
| Field | Description |
| dataToPrint (String) | Text sequence you want to print. |
| callback ((MPResponse<BluetoothPrinterResult>) -> Unit) | Request response feature that provides the result of the print request. The [MPResponse] includes the status, the error (if any), and the details in case of success, which contain a [BluetoothPrinterResult] object. |
| CONNECTION_FAILED | Indicates that the connection failed. |
| ERROR_UNDEFINED | Indicates that there is an error with an unknown cause. |
| SUCCESS | Indicates that the printing was successful. |
| NEED_SELECTION_DEVICE | Indicates that it’s necessary to specify the address of the devices when there’s more than one printer paired. |
| ERROR_DATA_TO_PRINT_NULL | Indicates that the details to print are null. |
| ERROR_PRINTER_NOT_FOUND | Indicates that no paired printers were found. |
Print using an external printer with a specific address
To print with an external printer identified by its address, use the print feature of the BluetoothPrinter class. Access must be through the MPManager object, as shown below.
val bluetoothPrinter = MPManager.bluetooth.printer
bluetoothPrinter.print(dataToPrint, address) { response ->
response
.doIfSuccess { printerResult ->
// Manage successful printing result
}.doIfError { error ->
// Manage the error case if necessary
}
}
final BluetoothPrinter bluetoothPrinter = MPManager.INSTANCE.getBluetooth().getPrinter();
final Function1<MPResponse<BluetoothPrinterResult>, Unit> callback =
(final MPResponse<BluetoothPrinterResult> response) -> {
if (response.getStatus() == ResponseStatus.SUCCESS) {
// Perform additional actions if necessary
} else {
// Manage the error case if necessary
}
return Unit.INSTANCE;
};
bluetoothPrinter.print(dataToPrint, address, callback);
| Field | Description |
| dataToPrint (String) | Text sequence you want to print. |
| address (String) | Address of the printer that will be used to print. |
| callback ((MPResponse<BluetoothPrinterResult>) -> Unit) | Request response feature that provides the result of the print request. The [MPResponse] includes the status, the error (if any), and the details in case of success, which contain a [BluetoothPrinterResult] object. |
| CONNECTION_FAILED | Indicates that the connection failed. |
| ERROR_UNDEFINED | Indicates that there is an error with an unknown cause. |
| SUCCESS | Indicates that the printing was successful. |
| NEED_SELECTION_DEVICE | Indicates that it’s necessary to specify the address of the devices when there’s more than one printer paired. |
| ERROR_DATA_TO_PRINT_NULL | Indicates that the details to print are null. |
| ERROR_PRINTER_NOT_FOUND | Indicates that no paired printers were found. |
