+# 🖨️ Dokumentasi Integrasi Printer Niimbot
+
+## 📋 Ringkasan
+
+Aplikasi kasir sekarang mendukung pencetakan QR Code langsung ke printer Niimbot menggunakan library `@mmote/niimbluelib` yang diadaptasi dari proyek niimblue.
+
+---
+
+## 🔧 Teknologi & Library
+
+### Library Utama
+- **@mmote/niimbluelib** - Library JavaScript untuk komunikasi dengan printer Niimbot
+  - Mendukung Web Bluetooth API
+  - Mendukung Web Serial API (USB)
+  - Encoding gambar ke format printer
+
+### Browser Support
+| Browser | Bluetooth | USB (Serial) |
+|---------|-----------|--------------|
+| Chrome/Edge (Desktop) | ✅ | ✅ |
+| Chrome (Android) | ✅ | ❌ |
+| Firefox | ❌ | ❌ |
+| Safari | ❌ | ❌ |
+
+**Rekomendasi:** Gunakan Chrome atau Edge versi terbaru
+

+
+## 📁 Struktur File
+
+```
+Kasir/resources/js/
+├── composables/
+│   └── useNiimbotPrinter.js       # Composable untuk koneksi & print
+├── components/
+│   ├── NiimbotConnector.vue       # Modal untuk koneksi printer
+│   └── BrankasList.vue            # Modifikasi: tambah fitur print Niimbot
+```
+
+---
+
+## 🚀 Cara Kerja
+
+### 1️⃣ Alur Koneksi Printer
+
+```
+User klik "Hubungkan Printer" 
+  → Modal NiimbotConnector muncul 
+  → Pilih metode: Bluetooth / USB
+  → Browser munculkan dialog pairing
+  → User pilih printer Niimbot
+  → Koneksi terjalin
+  → Fetch info printer
+  → Status: "Terhubung"
+```
+
+### 2️⃣ Alur Print QR Code
+
+```
+User klik item di Brankas
+  → Modal popup dengan QR Code
+  → User klik "Cetak ke Niimbot"
+  → Cek koneksi printer:
+     - Jika belum terhubung → tampilkan modal koneksi
+     - Jika sudah terhubung → lanjut
+  → Generate canvas dengan QR + info item
+  → Encode canvas ke format printer
+  → Kirim ke printer via library
+  → Status: "Mencetak... X%"
+  → Selesai
+```
+
+### 3️⃣ Komponen Kunci
+
+#### `useNiimbotPrinter.js` (Composable)
+```javascript
+// State management
+- printerClient         // Instance NiimbotClient
+- connectionState       // 'disconnected' | 'connecting' | 'connected'
+- connectedPrinterName  // Nama printer yang terhubung
+- printerInfo          // Info printer (model, serial, dll)
+- isPrinting           // Status sedang print
+- printProgress        // Progress print (0-100)
+
+// Methods
+- initClient(type)     // Init client (bluetooth/serial)
+- connect()            // Hubungkan ke printer
+- disconnect()         // Putuskan koneksi
+- printQRCode(dataUrl, options)  // Print QR code image
+```
+
+#### `NiimbotConnector.vue` (Component)
+- Modal untuk koneksi/disconnect printer
+- Pilih metode: Bluetooth atau USB
+- Tampilkan status koneksi
+- Tampilkan info printer detail
+
+#### `BrankasList.vue` (Modified)
+- Tombol "Hubungkan Printer" di header
+- Tombol "Cetak ke Niimbot" di modal item
+- Tombol "Browser" sebagai fallback
+- Alert sukses/error
+

+
+### 3. Build Assets
+```bash
+npm run build
+# atau untuk development
+npm run dev
+```
+
+---
+
+## 📖 Cara Penggunaan
+
+### A. Menghubungkan Printer
+
+1. **Persiapan Printer:**
+   - Nyalakan printer Niimbot
+   - Pastikan kertas label sudah terpasang
+   - Untuk Bluetooth: Aktifkan mode pairing (biasanya tahan tombol power)
+
+2. **Di Aplikasi:**
+   - Buka halaman Brankas
+   - Klik tombol "Hubungkan Printer" (di kanan atas)
+   - Pilih metode koneksi (Bluetooth/USB)
+   - Klik "Hubungkan Printer"
+   - Browser akan menampilkan dialog - pilih printer Niimbot Anda
+   - Tunggu hingga status berubah "Terhubung"
+
+### B. Mencetak QR Code
+
+1. **Pilih Item:**
+   - Klik item yang ingin dicetak QR-nya
+   - Modal akan muncul dengan QR Code
+
+2. **Cetak:**
+   - Klik tombol "Cetak ke Niimbot"
+   - Jika printer belum terhubung, akan muncul peringatan
+   - Progress print akan ditampilkan (Mencetak... X%)
+   - Tunggu hingga selesai
+
+3. **Alternatif:**
+   - Klik tombol "Browser" untuk print menggunakan printer biasa
+
+---
+
+## ⚙️ Konfigurasi Print
+
+Di file `BrankasList.vue`, fungsi `printQR()`:
+
+```javascript
+await printQRCode(imageDataUrl, {
+  density: 3,           // Kepadatan tinta (1-5, default: 3)
+  quantity: 1,          // Jumlah cetakan (default: 1)
+  labelType: 1,         // Tipe label:
+                        //   1 = WithGaps (label dengan jarak)
+                        //   2 = Continuous (tanpa jarak)
+                        //   3 = WithHoles (dengan lubang)
+  printTaskName: 'D110' // Model printer (D110, B21, B1, dll)
+                        // Auto-detect jika tidak cocok
+});
+```
+
+### Ukuran Label
+Di fungsi `createQRLabelCanvas()`:
+```javascript
+const labelWidth = 384;   // pixel (40mm @ 240dpi)
+const labelHeight = 384;  // pixel
+```
+
+**Sesuaikan dengan ukuran label Anda:**
+- 30mm x 30mm ≈ 288 x 288 px
+- 40mm x 40mm ≈ 384 x 384 px
+- 50mm x 30mm ≈ 480 x 288 px
+
+Rumus: `mm × (dpi / 25.4)`
+- DPI printer Niimbot umumnya: 203 atau 240
+
+---
+
+## 🐛 Troubleshooting
+
+### 1. "Browser tidak mendukung koneksi printer"
+**Solusi:**
+- Gunakan Chrome atau Edge versi terbaru
+- Update browser ke versi terkini
+- Pastikan menggunakan HTTPS (Web Bluetooth hanya jalan di HTTPS)
+
+### 2. "Gagal terhubung ke printer"
+**Solusi:**
+- Pastikan printer sudah dinyalakan
+- Pastikan Bluetooth/USB aktif
+- Coba matikan dan nyalakan ulang printer
+- Untuk Bluetooth: pastikan tidak paired ke device lain
+- Coba refresh halaman dan ulangi koneksi
+
+### 3. "Printer terhubung tapi tidak print"
+**Solusi:**
+- Periksa kertas label sudah terpasang dengan benar
+- Coba disconnect dan connect ulang
+- Periksa battery printer (untuk model portable)
+- Cek ukuran canvas sesuai dengan ukuran label
+
+### 4. "Print hasil blur/tidak jelas"
+**Solusi:**
+- Tingkatkan `density` (misal dari 3 ke 4)
+- Pastikan threshold image sudah optimal
+- Ukuran QR Code jangan terlalu kecil (min 150x150px)
+
+### 5. "Error: printTaskName not compatible"
+**Solusi:**
+- Ganti `printTaskName` sesuai model printer:
+  - D110: `'D110'`
+  - B21: `'B21'`
+  - B1: `'B1'`
+  - Atau hapus parameter, biarkan auto-detect
+
+---
+
+## 🔍 Debugging
+
+### Enable Console Logs
+Library sudah dilengkapi logging:
+```javascript
+// Di browser console akan muncul:
+>> Packet sent: [hex bytes]
+<< Packet received: [hex bytes]
+Printer connected: { deviceName: "Niimbot-XXXX" }
+Printer info fetched: { model: "D110", ... }
+```
+
+### Test Print Canvas
+Tambahkan debug preview sebelum print:
+```javascript
+// Di createQRLabelCanvas, sebelum resolve(canvas):
+document.body.appendChild(canvas); // Tampilkan canvas di halaman
+canvas.style.border = '1px solid red';
+```
+

+

+
+## 🎨 Customization
+
+### Ubah Desain Label
+Edit fungsi `createQRLabelCanvas()` di `BrankasList.vue`:
+
+```javascript
+// Contoh: Tambah logo toko
+const logo = new Image();
+logo.src = '/path/to/logo.png';
+logo.onload = () => {
+  ctx.drawImage(logo, 10, 10, 50, 50);
+};
+
+// Contoh: Tambah border
+ctx.strokeStyle = 'black';
+ctx.lineWidth = 2;
+ctx.strokeRect(5, 5, labelWidth - 10, labelHeight - 10);
+
+// Contoh: Font custom
+ctx.font = 'bold 20px "Courier New"';
+```
+
+### Tambah Barcode
+Install library barcode:
+```bash
+npm install jsbarcode
+```
+
+Implementasi:
+```javascript
+import JsBarcode from 'jsbarcode';
+
+const barcodeCanvas = document.createElement('canvas');
+JsBarcode(barcodeCanvas, item.kode_item, {
+  format: 'CODE128',
+  width: 2,
+  height: 40,
+});
+ctx.drawImage(barcodeCanvas, x, y);
+```
+
+---
+
+## 📝 Catatan Penting
+
+1. **HTTPS Required**: Web Bluetooth & Web Serial hanya bekerja di HTTPS (kecuali localhost)
+2. **User Gesture**: Koneksi harus dipicu oleh user action (klik button), tidak bisa otomatis on load
+3. **One Printer**: Satu browser session hanya bisa terhubung ke 1 printer
+4. **Battery**: Printer portable akan disconnect otomatis jika battery rendah
+5. **Label Size**: Sesuaikan ukuran canvas dengan ukuran label fisik untuk hasil optimal
+
+---
+
+## 🆘 Support
+
+Jika ada masalah:
+1. Periksa console browser (F12 → Console)
+2. Periksa kompatibilitas browser
+3. Periksa dokumentasi printer Niimbot Anda
+4. Issue library: https://github.com/MultiMote/niimbluelib
