Add this permission request constant:
private final int PERMISSION_REQUEST_BLUETOOTH_CONNECT = 432;Check and request permissions in your Activity:
private void checkBluetoothPermission() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_CONNECT) == PackageManager.PERMISSION_GRANTED
|| ContextCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_SCAN) == PackageManager.PERMISSION_GRANTED) {
// Permission granted - proceed with printer operations
connectToPrinter();
} else {
// Request permissions
requestBluetoothPermission();
}
}
private void requestBluetoothPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
// Android 12+ - Request new Bluetooth permissions
ActivityCompat.requestPermissions(this,
new String[]{
Manifest.permission.BLUETOOTH_SCAN,
Manifest.permission.BLUETOOTH_CONNECT
},
PERMISSION_REQUEST_BLUETOOTH_CONNECT);
} else {
// Older Android versions - Request Bluetooth enable
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, PERMISSION_REQUEST_BLUETOOTH_CONNECT);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSION_REQUEST_BLUETOOTH_CONNECT) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission granted
connectToPrinter();
} else {
// Permission denied
Toast.makeText(this, "Bluetooth permission is required for printing", Toast.LENGTH_LONG).show();
}
}
}Call permission check in your onCreate() method:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Check permissions when activity starts
checkBluetoothPermission();
}Show dialog to choose bonded device (printer list) bind your device initially from the bluetooth config:
Printama.showPrinterList(this, printerName -> {
// Your code here
});Show dialog to choose bonded device (Custom Color)
Printama.showPrinterList(this, R.color.colorBlue, printerName -> {
if (connectedPrinter != null) {
// Your code here
}
});Prepare the text
String text = "-------------\n" +
"This will be printed\n" +
"Left aligned\n" + // or Center or Right
"cool isn't it?\n" +
"------------------\n";Print Text LEFT aligned
Printama.with(context).connect(printama -> {
printama.printText(text, PA.LEFT);

});🆕 Advanced Column Formatting (New in 0.9.80)
Printama now includes powerful column formatting methods that automatically handle width calculation and text alignment:
Printama.with(this).connect(printama -> {
// Two columns with default widths (70% - 30%)
printama.printTextln(printama.formatTwoColumns("Product", "Price"), PA.LEFT);
printama.printTextln(printama.formatTwoColumns("Coffee", "$3.50"), PA.LEFT);
// Three columns with default widths (50% - 20% - 30%)
printama.printTextln(printama.formatThreeColumns("Item", "Qty", "Total"), PA.LEFT);
printama.printTextln(printama.formatThreeColumns("Espresso", "2", "$7.00"), PA.LEFT);
// Four columns with default widths (40% - 20% - 20% - 20%)
printama.printTextln(printama.formatFourColumns("ID", "Name", "Stock", "Price"), PA.LEFT);
printama.printTextln(printama.formatFourColumns("001", "Coffee", "50", "$3.50"), PA.LEFT);
// Five columns with default widths (30% - 20% - 20% - 15% - 15%)
printama.printTextln(printama.formatFiveColumns("ID", "Item", "Cat", "Qty", "$"), PA.LEFT);
// Custom column widths (percentages must sum to 100)
double[] customWidths = {60.0, 40.0}; // 60% - 40%
printama.printTextln(printama.formatTwoColumns("Description", "Amount", customWidths), PA.LEFT);
printama.close();
});Print Text with format
Printama.with(this).connect(printama -> {

printama.close();
});Print Bitmap / Image CENTER aligned
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
printama.printImage(bitmap, 200, PA.CENTER);
printama.close();
});Print Bitmap / Image RIGHT aligned
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
printama.printImage(bitmap, 200, PA.RIGHT);
printama.close();
});Print Bitmap / Image FULL size
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

Using print layout view, you can design your receipt on your layout XML or DSL, and pass the root view as a parameter:
View view = findViewById(R.id.root_view);
Printama.with(this).connect(printama -> {
printama.printFromView(view);
printama.close();

Important: Version 1.0.0 introduces new constant classes for better organization. The old constants are deprecated and will be removed in v2.0.0.
| ❌ Deprecated (v0.9.x) | ✅ New (v1.0.0+) | Description |
|---|---|---|
Printama.LEFT |
PA.LEFT |
Left text alignment |
Printama.CENTER |
PA.CENTER |
Center text alignment |
Printama.RIGHT |
PA.RIGHT |
Right text alignment |
| ❌ Deprecated (v0.9.x) | ✅ New (v1.0.0+) | Description |
|---|---|---|
Printama.ORIGINAL_WIDTH |
PW.ORIGINAL_WIDTH |
Original image width |
Printama.FULL_WIDTH |
PW.FULL_WIDTH |
Full printer width |
Text Methods:
// ❌ Old way (deprecated)
printText(PA.CENTER, "Hello World");
printTextln(PA.RIGHT, "Hello World");
// ✅ New way
printText("Hello World", PA.CENTER);
printTextln("Hello World", PA.RIGHT);Image Methods:
// ❌ Old way (deprecated)
printImage(PA.CENTER, bitmap, PW.FULL_WIDTH);
// ✅ New way
printImage(bitmap, PW.FULL_WIDTH, PA.CENTER);import com.anggastudio.printama.Printama;
import com.anggastudio.printama.constants.PA; // For alignment constants
import com.anggastudio.printama.constants.PW; // For width constants- Replace
Printama.LEFT/CENTER/RIGHTwithPA.LEFT/CENTER/RIGHT - Replace
Printama.ORIGINAL_WIDTH/FULL_WIDTHwithPW.ORIGINAL_WIDTH/FULL_WIDTH - Update text method calls:
printText(align, text)→printText(text, align) - Update image method calls:
printImage(align, bitmap, width)→printImage(bitmap, width, align) - Add import statements for
PAandPWclasses - Test your implementation with the new API
💡 Tip: The deprecated methods will continue to work in v1.0.0 but will show compiler warnings. Plan to migrate before v2.0.0 release.
