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:

});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();
});- Dialog to choose bonded bluetooth device list.
- Print Text with LEFT, CENTER, or RIGHT Alignment.
- Print Text with JUSTIFY Alignment.
- Print auto grayscale Bitmap with Custom width and Alignment.
- Print photo (grayscaled)
- Print your android screen or layout by passing the root view
- Print vector drawable
- Tested with 2 inch Bluetooth Thermal Printers.
You can simply :
- a pull request, or
- raise an issue ticket, or
- request additional feature by raise a ticket.
- Minimum Android SDK Version 16
- Always check latest release
Step 1. Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Step 2. Add the dependency
version:
dependencies {
implementation 'com.github.anggastudio:Printama:<version>'just visit the jitpack page click here -->
- release 1.0.0 to make it more stable
- enhance documentation
- create a video tutorial
- 3 inches printer
- testing on more printer brands
- (still in my mind) migrate to kotlin
