Printama

Android library for bluetooth thermal printer.

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:

Show dialog to choose bonded device bind your device initially from the bluetooth config:

Printama.showPrinterList(this, printerName -> {
    ...
});

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 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 parameter

View view = findViewById(R.id.root_view);
Printama.with(this).connect(printama -> {
    printama.printFromView(view);
    printama.close();
});
