Getting Started

1. Add the dependency

dependencies:
  zebra_usb_printer: ^0.0.1

2. Android permissions

Add the following to your app's AndroidManifest.xml inside <manifest>:

<uses-feature android:name="android.hardware.usb.host" />

And inside <application>, add a USB device filter to your main <activity>:

<intent-filter>
    <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<meta-data
    android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
    android:resource="@xml/usb_device_filter" />

Create res/xml/usb_device_filter.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <usb-device vendor-id="2655" /> <!-- Zebra Technologies vendor ID -->
</resources>

---

Usage

import 'package:zebra_usb_printer/zebra_usb_printer.dart';

// Check printer status
final status = await ZebraUsbPrinter.getPrinterStatus();
// Returns: "READY" | "NOT_FOUND" | "PERMISSION_REQUIRED" | "ERROR: <message>"

// Print a ZPL label
final result = await ZebraUsbPrinter.printLabel('^XA^FO50,50^ADN,36,20^FDHello World^FS^XZ');

Printer status values

Value	Meaning
READY	Printer found and connection succeeded
NOT_FOUND	No Zebra USB printer detected
PERMISSION_REQUIRED	Printer found but USB permission not yet granted
ERROR: <message>	An error occurred while communicating with the printer

---

Notes

• Only Zebra printers (USB Vendor ID 0x0A5F / 2655) are detected.
• USB permission is requested automatically on first use if not already granted.
• The plugin uses Android's UsbManager API directly — no third-party SDKs required at runtime.
