API HELP – Simple Bluetooth Printer

1. Open your application

2. Create intent as below

Intent intent = new Intent();
intent.setComponent(new ComponentName(“com.iyaltamizh.bluetoothprint”, “com.iyaltamizh.bluetoothprint.Print”));
intent.putExtra(“content”,”Hello World”);
startActivity(intent);

3. create intent with componentName “com.iyaltamizh.bluetoothprint” and activity name is “com.iyaltamizh.bluetoothprint.Print”

4. Load your print content in putExtras as “content”

5. Start activity.

When to Use the Print Intent API

This API is for developers integrating Simple Bluetooth Printer into their own Android app — for example, a custom POS, inventory, or billing app that needs to trigger a print job without opening Simple Bluetooth Printer's own UI. Instead of building your own Bluetooth/ESC-POS printing stack, you hand off the content as plain text and let Simple Bluetooth Printer handle pairing, connection, and the actual print job.

Full Example

Intent intent = new Intent();
intent.setComponent(new ComponentName(
    "com.iyaltamizh.bluetoothprint",
    "com.iyaltamizh.bluetoothprint.Print"
));
intent.putExtra("content", "Hello World");
startActivity(intent);

The receiving activity opens Simple Bluetooth Printer with the given content string queued for printing. If a printer is already selected in the app (see the main setup guide), the print happens immediately; otherwise the user is prompted to pick a paired printer first.

Troubleshooting

• Nothing happens on startActivity(): confirm Simple Bluetooth Printer is installed on the target device — the intent silently fails if the component isn't found.
• Garbled or missing characters: see the encoding guide for selecting the correct character set for non-ASCII content.
• Need images, QR codes, or barcodes, not just text: those aren't supported through this lightweight intent API — use the in-app editor for anything beyond plain text.
