Usage

Currently still in Alpha. Make sure to use Java 8+ configuration. Documentation is in progress. Just take a look at sample project as an example.

But here for an insight: Permissions in your Manifest

<uses-permission android:name="android.permission.BLUETOOTH_SCAN"  android:usesPermissionFlags="neverForLocation"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

Permission check in your Activity. Call checkPermissions() in your onCreate() method

private static String[] PERMISSIONS_STORAGE = {
    Manifest.permission.READ_EXTERNAL_STORAGE,
    Manifest.permission.WRITE_EXTERNAL_STORAGE,
    Manifest.permission.ACCESS_FINE_LOCATION,
    Manifest.permission.ACCESS_COARSE_LOCATION,
    Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS,
    Manifest.permission.BLUETOOTH_SCAN,
    Manifest.permission.BLUETOOTH_CONNECT,
    Manifest.permission.BLUETOOTH_PRIVILEGED
};

private static String[] PERMISSIONS_LOCATION = {
    Manifest.permission.ACCESS_FINE_LOCATION,
    Manifest.permission.ACCESS_COARSE_LOCATION,
    Manifest.permission.ACCESS_LOCATION_EXTRA_COMMANDS,
    Manifest.permission.BLUETOOTH_SCAN,
    Manifest.permission.BLUETOOTH_CONNECT,
    Manifest.permission.BLUETOOTH_PRIVILEGED
};

private void checkPermissions() {
    int permission1 = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    int permission2 = ActivityCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_SCAN);

    if (permission1 != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(
                this,
                PERMISSIONS_STORAGE,
                1
        );
    } else if (permission2 != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
                this,
                PERMISSIONS_LOCATION,
                1
        );
    }
}

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(Printama.LEFT, text);
    printama.close();
});

Print Text CENTER aligned

Printama.with(context).connect(printama -> {
    printama.printText(Printama.CENTER, text);
    printama.close();
});

Print Text RIGHT aligned

Printama.with(context).connect(printama -> {
    printama.printText(Printama.RIGHT, text);
    printama.close();
});

Print Text JUSTIFY aligned

Printama.with(this).connect(printama -> {
    printama.printTextJustify("text1", "text2");
    printama.printTextJustify("text1", "text2", "text3");
    printama.printTextJustify("text1", "text2", "text3", "text4");

    printama.printTextJustifyBold("text1", "text2");
    printama.printTextJustifyBold("text1", "text2", "text3");
    printama.printTextJustifyBold("text1", "text2", "text3", "text4");

    printama.setNormalText();
    printama.feedPaper();
    printama.close();
});

Print Text with format

Printama.with(this).connect(printama -> {
    printama.setSmallText();
    printama.printText("small___________");
    printama.printTextln("TEXTtext");

    printama.setNormalText();
    printama.printText("normal__________");
    printama.printTextln("TEXTtext");

    printama.printTextNormal("bold____________");
    printama.printTextlnBold("TEXTtext");

    printama.setNormalText();
    printama.printTextNormal("tall____________");
    printama.printTextlnTall("TEXTtext");

    printama.printTextNormal("tall bold_______");
    printama.printTextlnTallBold("TEXTtext");

    printama.printTextNormal("wide____________");
    printama.printTextlnWide("TEXTtext");

    printama.printTextNormal("wide bold_______");
    printama.printTextlnWideBold("TEXTtext");

    printama.printTextNormal("wide tall_______");
    printama.printTextlnWideTall("TEXTtext");

    printama.printTextNormal("wide tall bold__");
    printama.printTextlnWideTallBold("TEXTtext");

    printama.printTextNormal("underline_______");
    printama.setUnderline();
    printama.printTextln("TEXTtext");

    printama.printTextNormal("delete line_____");
    printama.setDeleteLine();
    printama.printTextln("TEXTtext");

    printama.setNormalText();
    printama.feedPaper();
    printama.close();
});

Print Bitmap / Image LEFT aligned

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
    printama.printImage(Printama.LEFT, bitmap, 200);
    printama.close();
});

Print Bitmap / Image CENTER aligned

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
    printama.printImage(Printama.CENTER, bitmap, 200);
    printama.close();
});

Print Bitmap / Image RIGHT aligned

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
    printama.printImage(Printama.RIGHT, bitmap, 200);
    printama.close();
});

Print Bitmap / Image FULL size

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
    printama.printImage(bitmap, Printama.FULL_WIDTH);
    printama.close();
});

Print Bitmap / Image ORIGINAL size

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
Printama.with(context).connect(printama -> {
    printama.printImage(bitmap); // original size, centered as default
    printama.close();
});

Print Drawable Vector

Bitmap bitmap = Printama.getBitmapFromVector(this, R.drawable.ic_launcher_background);
Printama.with(this).connect(printama -> {
    printama.printImage(bitmap, Printama.ORIGINAL_WIDTH);
    printama.close();
});

Print Layout View

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();
});
