||||
|
||||
1. Open **Google Chrome**
|
||||
2. Navigate to `chrome://extensions/`
|
||||
3. Enable **"Developer mode"** (toggle in top-right corner)
|
||||
4. Click **"Load unpacked"**
|
||||
5. Select the `chrome_extension` folder
|
||||

|
||||
```
|
||||
|
||||
#### Test Chrome Extension
|
||||
|
||||
1. Click the extension icon in Chrome toolbar
|
||||
2. Verify it shows "Service Status: Connected ✅"
|
||||
3. Check that printers are listed
|
||||
4. Try the "Test Print" button
|
||||
|
||||
## 🔄 Web Application Integration
|
||||
|
||||
The web application automatically detects the Windows service and adapts the user interface:
|
||||
|
||||
### Service Available (Green Button)
|
||||
- Button text: **"🖨️ Print Labels (Silent)"**
|
||||
- Functionality: Direct printing to default printer
|
||||
- User experience: Click → Labels print immediately
|
||||
|
||||
### Service Unavailable (Blue Button)
|
||||
- Button text: **"📄 Generate PDF"**
|
||||
- Functionality: PDF download for manual printing
|
||||
- User experience: Click → PDF downloads to browser
|
||||
|
||||
### Detection Logic
|
||||
```javascript
|
||||
// Automatic service detection on page load
|
||||
const response = await fetch('http://localhost:8765/health');
|
||||
if (response.ok) {
|
||||
// Service available - enable silent printing
|
||||
} else {
|
||||
// Service unavailable - fallback to PDF download
|
||||
}
|
||||
```
|
||||
|
||||

||||
|---------------|-------------------|--------------|
|
||||
| **Running** ✅ | 🖨️ **Print Labels (Silent)** (Green) | Direct printing |
|
||||
| **Not Running** ❌ | 📄 **Generate PDF** (Blue) | PDF download |
|
||||
|
||||
## ⚠️ Troubleshooting
|
||||
|
||||
| Problem | Solution |
|
||||
|---------|----------|
|
||||
| **Service won't start** | Run `install_service.bat` as Administrator |
|
||||
| **Chrome extension not working** | Reload extension in `chrome://extensions/` |
|
||||
| **Can't connect to localhost:8765** | Check Windows Firewall (port 8765) |
|
||||
| **Nothing prints** | Verify default printer is set up |
|
||||
|
||||
## 🔧 Management Commands
|
||||
|
||||
```bash
|
||||
# Check service status
|
||||
python service_manager.py status
|
||||
|
||||
# Restart service
|
||||
python service_manager.py restart
|
||||
|
||||
# Uninstall service
|
||||
python service_manager.py uninstall
|
||||
```
|
||||
|
||||
## 📍 Important Notes
|
||||
|
||||
- ⚡ **Auto-starts** with Windows - no manual intervention needed
|
||||
- 🔒 **Local only** - service only accessible from same computer
|
||||
- 🖨️ **Uses default printer** - configure your default printer in Windows
|
||||
- 💾 **Don't move files** after installation - keep folder in same location
|
||||
|
||||

|
||||
const health = await fetch('http://localhost:8765/health');
|
||||
const status = await health.json();
|
||||
|
||||

|
||||
method: 'POST',
|
||||
headers: {'Content-Type': 'application/json'},
|
||||
body: JSON.stringify(printRequest)
|
||||
});
|
||||
```
|
||||
|
||||
## 🔧 Development Setup
|
||||
|
||||
### Prerequisites
|
||||
- Python 3.8+
|
||||
- Windows 10/11
|
||||
- Chrome Browser
|
||||
- Administrator privileges
|
||||
|
||||
### Local Development
|
||||
|
||||
```bash
|
||||
# Clone/download the project
|
||||
cd windows_print_service
|
||||
|
||||
# Install dependencies
|
||||
pip install flask flask-cors requests pywin32
|
||||
|
||||
# Run development server (not as service)
|
||||
python print_service.py
|
||||
|
||||
# Install as Windows service
|
||||
python service_manager.py install
|
||||
|
||||
# Service management
|
||||
python service_manager.py start
|
||||
python service_manager.py stop
|
||||
python service_manager.py restart
|
||||
python service_manager.py uninstall
|
||||
```
|
||||
|
||||
### Chrome Extension Development
|
||||
|
||||
```bash
|
||||
# Load extension in Chrome
|
||||
chrome://extensions/ → Developer mode ON → Load unpacked
|
||||
|
||||
# Debug extension
|
||||
chrome://extensions/ → Details → Background page (for service worker)
|
||||
chrome://extensions/ → Details → Inspect views (for popup)
|
||||
```
|
||||
|
||||
## 📋 Configuration
|
||||
|
||||
### Service Configuration (`print_service.py`)
|
||||
|
||||
```python
|
||||
class WindowsPrintService:
|
||||
def __init__(self, host='127.0.0.1', port=8765):
|
||||
self.host = host # Localhost binding only
|
||||
self.port = port # Service port
|
||||
self.app = Flask(__name__)
|
||||
```
|
||||
|
||||
### Chrome Extension Permissions (`manifest.json`)
|
||||
|
||||
```json
|
||||
{
|
||||
"permissions": [
|
||||
"printing", // Access to printer API
|
||||
"nativeMessaging", // Communication with Windows service
|
||||
"activeTab", // Current tab access
|
||||
"storage" // Extension settings storage
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## 🔄 Integration Flow
|
||||
|
||||
### 1. Service Detection
|
||||
```javascript
|
||||
// Web page detects service availability
|
||||
const isServiceAvailable = await checkServiceHealth();
|
||||
updatePrintButton(isServiceAvailable);
|
||||
```
|
||||
|
||||
### 2. Print Request Flow
|
||||
```
|
||||
User clicks print → Web app → Windows service → Chrome extension → Printer
|
||||
```
|
||||
|
||||
### 3. Fallback Mechanism
|
||||
```
|
||||
Service unavailable → Fallback to PDF download → Manual printing
|
||||
```
|
||||
|
||||
## 🛠️ Customization
|
||||
|
||||
### Adding New Print Options
|
||||
|
||||
```python
|
||||
# In print_service.py
|
||||
@app.route('/print/custom', methods=['POST'])
|
||||
def print_custom():
|
||||
data = request.json
|
||||
# Custom print logic here
|
||||
return jsonify({'success': True})
|
||||
```
|
||||
|
||||
### Modifying Chrome Extension
|
||||
|
||||
```javascript
|
||||
// In background.js - Add new message handler
|
||||
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
|
||||
if (message.type === 'CUSTOM_PRINT') {
|
||||
// Custom print logic
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Web Application Integration
|
||||
|
||||
```javascript
|
||||
// In print_module.html - Modify print function
|
||||
async function customPrintFunction(orderId) {
|
||||
const response = await fetch('http://localhost:8765/print/custom', {
|
||||
method: 'POST',
|
||||
body: JSON.stringify({orderId, customOptions: {...}})
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
### Unit Tests (Future Enhancement)
|
||||
|
||||
```python
|
||||
# test_print_service.py
|
||||
import unittest
|
||||
from print_service import WindowsPrintService
|
||||
|
||||
class TestPrintService(unittest.TestCase):
|
||||
def test_health_endpoint(self):
|
||||
# Test implementation
|
||||
pass
|
||||
```
|
||||
|
||||
### Manual Testing Checklist
|
||||
|
||||
- [ ] Service starts automatically on Windows boot
|
||||
- [ ] API endpoints respond correctly
|
||||
- [ ] Chrome extension loads without errors
|
||||
- [ ] Print jobs execute successfully
|
||||
- [ ] Fallback works when service unavailable
|
||||
- [ ] Firewall allows port 8765 traffic
|
||||
|
||||
## 📊 Monitoring & Logging
|
||||
|
||||
### Log Files
|
||||
- **Service Log**: `print_service.log` (Flask application logs)
|
||||
- **Windows Event Log**: Windows Services logs
|
||||
- **Chrome DevTools**: Extension console logs
|
||||
|
||||
### Health Monitoring
|
||||
|
||||
```python
|
||||
# Monitor service health
|
||||
import requests
|
||||
try:
|
||||
response = requests.get('http://localhost:8765/health', timeout=5)
|
||||
if response.status_code == 200:
|
||||
print("✅ Service healthy")
|
||||
except:
|
||||
print("❌ Service unavailable")
|
||||
```
|
||||
|
||||
## 🔒 Security Considerations
|
||||
|
||||
### Network Security
|
||||
- **Localhost Only**: Service binds to 127.0.0.1 (no external access)
|
||||
- **No Authentication**: Relies on local machine security
|
||||
- **Firewall Rule**: Port 8765 opened for local connections only
|
||||
|
||||
### Chrome Extension Security
|
||||
- **Manifest V3**: Latest security standards
|
||||
- **Minimal Permissions**: Only necessary permissions requested
|
||||
- **Sandboxed**: Runs in Chrome's security sandbox
|
||||
|
||||
### Windows Service Security
|
||||
- **System Service**: Runs with appropriate Windows service privileges
|
||||
- **Print Permissions**: Requires printer access (normal for print services)
|
||||
|
||||
## 🚀 Deployment
|
||||
|
||||
### Production Deployment
|
||||
|
||||
1. **Package Distribution**:
|
||||
```bash
|
||||
# Create deployment package
|
||||
zip -r quality_recticel_print_service.zip windows_print_service/
|
||||
```
|
||||
|
||||
2. **Installation Script**: Use `install_service.bat` for end users
|
||||
|
||||
3. **Group Policy Deployment**: Deploy Chrome extension via enterprise policies
|
||||
|
||||
### Enterprise Considerations
|
||||
|
||||
- **Silent Installation**: Modify `install_service.bat` for unattended install
|
||||
- **Registry Deployment**: Pre-configure Chrome extension registry entries
|
||||
- **Network Policies**: Ensure firewall policies allow localhost:8765
|
||||
|
||||

|
||||
```
|
||||
|
||||
## 🔧 Prerequisites
|
||||
|
||||
### System Requirements
|
||||
- **Operating System**: Windows 10/11 (64-bit)
|
||||
- **Python**: Python 3.8 or higher
|
||||
- **Browser**: Google Chrome (latest version)
|
||||
- **Privileges**: Administrator access required for installation
|
||||
|
||||
### Python Dependencies
|
||||
The following packages will be installed automatically:
|
||||
- `flask` - Web service framework
|
||||
- `flask-cors` - Cross-origin resource sharing
|
||||
- `requests` - HTTP client library
|
||||
- `pywin32` - Windows service integration
|
||||
|
||||
## 🚀 Installation Process
|
||||
|
||||
### Step 1: Download and Extract Files
|
||||
|
||||
1. Download the `windows_print_service` folder to your system
|
||||
2. Extract to a permanent location (e.g., `C:\QualityRecticel\PrintService\`)
|
||||
3. **Do not move or delete this folder after installation**
|
||||
|
||||
### Step 2: Install Windows Service
|
||||
|
||||
#### Method A: Automated Installation (Recommended)
|
||||
|
||||
1. **Right-click** on `install_service.bat`
|
||||
2. Select **"Run as administrator"**
|
||||
3. Click **"Yes"** when Windows UAC prompt appears
|
||||
4. Wait for installation to complete
|
||||
|
||||
#### Method B: Manual Installation
|
||||
|
||||
If the automated script fails, follow these steps:
|
||||
|
||||
```bash
|
||||
# Open Command Prompt as Administrator
|
||||
cd C:\path\to\windows_print_service
|
||||
|
||||
# Install Python dependencies
|
||||
pip install flask flask-cors requests pywin32
|
||||
|
||||
# Install Windows service
|
||||
python service_manager.py install
|
||||
|
||||
# Add firewall exception
|
||||
netsh advfirewall firewall add rule name="Quality Recticel Print Service" dir=in action=allow protocol=TCP localport=8765
|
||||
|
||||
# Create Chrome extension registry entry
|
||||
reg add "HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts\com.qualityrecticel.printservice" /ve /d "%cd%\chrome_extension\manifest.json" /f
|
||||
```
|
||||
|
||||
### Step 3: Install Chrome Extension
|
||||
|
||||
1. Open **Google Chrome**
|
||||
2. Navigate to `chrome://extensions/`
|
||||
3. Enable **"Developer mode"** (toggle in top-right corner)
|
||||
4. Click **"Load unpacked"**
|
||||
5. Select the `chrome_extension` folder
|
||||
6. Verify the extension appears with a printer icon
|
||||
|
||||
### Step 4: Verify Installation
|
||||
|
||||
#### Check Windows Service Status
|
||||
|
||||
1. Press `Win + R`, type `services.msc`, press Enter
|
||||
2. Look for **"Quality Recticel Print Service"**
|
||||
3. Status should show **"Running"**
|
||||
4. Startup type should be **"Automatic"**
|
||||
|
||||
#### Test API Endpoints
|
||||
|
||||
Open a web browser and visit:
|
||||
- **Health Check**: `http://localhost:8765/health`
|
||||
- **Printer List**: `http://localhost:8765/printers`
|
||||
|
||||
Expected response for health check:
|
||||
```json
|
||||
{
|
||||
"status": "healthy",
|
||||
"service": "Quality Recticel Print Service",
|
||||
"version": "1.0",
|
||||
"timestamp": "2025-09-21T10:30:00"
|
||||
}
|
||||
```
|
||||
|
||||
#### Test Chrome Extension
|
||||
|
||||
1. Click the extension icon in Chrome toolbar
|
||||
2. Verify it shows "Service Status: Connected ✅"
|
||||
3. Check that printers are listed
|
||||
4. Try the "Test Print" button
|
||||
|
||||
## 🔄 Web Application Integration
|
||||
|
||||
The web application automatically detects the Windows service and adapts the user interface:
|
||||
|
||||
### Service Available (Green Button)
|
||||
- Button text: **"🖨️ Print Labels (Silent)"**
|
||||
- Functionality: Direct printing to default printer
|
||||
- User experience: Click → Labels print immediately
|
||||
|
||||
### Service Unavailable (Blue Button)
|
||||
- Button text: **"📄 Generate PDF"**
|
||||
- Functionality: PDF download for manual printing
|
||||
- User experience: Click → PDF downloads to browser
|
||||
|
||||
### Detection Logic
|
||||
```javascript
|
||||
// Automatic service detection on page load
|
||||
const response = await fetch('http://localhost:8765/health');
|
||||
if (response.ok) {
|
||||
// Service available - enable silent printing
|
||||
} else {
|
||||
// Service unavailable - fallback to PDF download
|
||||
}
|
||||
```
|
||||
|
||||
## 🛠️ Configuration
|
||||
|
||||
### Service Configuration
|
||||
|
||||
The service runs with the following default settings:
|
||||
|
||||
| Setting | Value | Description |
|
||||
|---------|-------|-------------|
|
||||
| **Port** | 8765 | Local API port |
|
||||
| **Host** | localhost | Service binding |
|
||||
| **Startup** | Automatic | Starts with Windows |
|
||||
| **Printer** | Default | Uses system default printer |
|
||||
| **Copies** | 1 | Default print copies |
|
||||
|
||||
### Chrome Extension Permissions
|
||||
|
||||
The extension requires these permissions:
|
||||
- `printing` - Access to printer functionality
|
||||
- `nativeMessaging` - Communication with Windows service
|
||||
- `activeTab` - Access to current webpage
|
||||
- `storage` - Save extension settings
|
||||
|
||||
## 🔍 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### 1. Service Not Starting
|
||||
**Symptoms**: API not accessible at localhost:8765
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Check service status
|
||||
python -c "from service_manager import service_status; service_status()"
|
||||
|
||||
# Restart service manually
|
||||
python service_manager.py restart
|
||||
|
||||
# Check Windows Event Viewer for service errors
|
||||
```
|
||||
|
||||
#### 2. Chrome Extension Not Working
|
||||
**Symptoms**: Extension shows "Service Status: Disconnected ❌"
|
||||
**Solutions**:
|
||||
- Verify Windows service is running
|
||||
- Check firewall settings (port 8765 must be open)
|
||||
- Reload the Chrome extension
|
||||
- Restart Chrome browser
|
||||
|
||||
#### 3. Firewall Blocking Connection
|
||||
**Symptoms**: Service runs but web page can't connect
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Add firewall rule manually
|
||||
netsh advfirewall firewall add rule name="Quality Recticel Print Service" dir=in action=allow protocol=TCP localport=8765
|
||||
|
||||
# Or disable Windows Firewall temporarily to test
|
||||
```
|
||||
|
||||
#### 4. Permission Denied Errors
|
||||
**Symptoms**: Installation fails with permission errors
|
||||
**Solutions**:
|
||||
- Ensure running as Administrator
|
||||
- Check Windows UAC settings
|
||||
- Verify Python installation permissions
|
||||
|
||||
#### 5. Print Jobs Not Processing
|
||||
**Symptoms**: API accepts requests but nothing prints
|
||||
**Solutions**:
|
||||
- Check default printer configuration
|
||||
- Verify printer drivers are installed
|
||||
- Test manual printing from other applications
|
||||
- Check Windows Print Spooler service
|
||||
|
||||

||||
|
||||
Check these locations for troubleshooting:
|
||||
|
||||
| Component | Log Location |
|
||||

|
||||
sc start QualityRecticelPrintService
|
||||
|
||||
# Stop service
|
||||
sc stop QualityRecticelPrintService
|
||||
|
||||
# Check status
|
||||
sc query QualityRecticelPrintService
|
||||
|
||||
# Restart service
|
||||
sc stop QualityRecticelPrintService && sc start QualityRecticelPrintService
|
||||
```
|
||||
|
||||
### Using Services GUI
|
||||
1. Press `Windows + R`, type `services.msc`

|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Service Won't Start
|
||||
1. **Check Administrator Rights**: Ensure installer was run as Administrator
|
||||
2. **PowerShell Execution Policy**: Verify PowerShell execution policy allows scripts
|
||||
```powershell
|
||||
Get-ExecutionPolicy
|
||||
# Should be RemoteSigned or Unrestricted
|
||||
```
|
||||
3. **Port Conflict**: Check if port 8765 is already in use
|
||||
```cmd
|
||||
netstat -ano | findstr :8765
|
||||
```
|
||||
4. **Service Logs**: Check the log file for detailed error messages
|
||||
|
||||
### Printing Issues
|
||||
1. **Printer Access**: Verify printers are accessible from Windows services
|
||||
2. **PDF Access**: Ensure PDF URLs are accessible from the service context
|
||||
3. **Print Queue**: Check Windows print queue for stuck jobs
|
||||
4. **Permissions**: Verify service has permission to access printers
|
||||
|
||||
### Chrome Extension Issues
|
||||
1. **Service Connection**: Test http://localhost:8765/health in browser
|
||||
2. **Extension Loading**: Verify extension is properly loaded in Chrome
|
||||
3. **CORS**: Service includes proper CORS headers for browser access
|
||||
4. **Console Errors**: Check browser console for JavaScript errors
|
||||
|
||||
## Security Features
|
||||
|
||||
- **Localhost Only**: Service only accepts connections from 127.0.0.1/localhost
|
||||
- **No External Access**: No outbound network requirements except for PDF downloads
|
||||
- **Temporary Files**: PDF downloads are cleaned up automatically
|
||||
- **Service Account**: Runs with minimal required privileges
|
||||
- **CORS Protection**: Proper cross-origin resource sharing headers
|
||||
|
||||
## Uninstallation
|
||||
|
||||
### Automated Uninstall
|
||||
```batch
|
||||
# Right-click and "Run as administrator"
|
||||
uninstall_service.bat
|
||||
```
|
||||
|
||||
### Manual Uninstall
|
||||
```batch
|
||||
# Stop and delete service
|
||||
sc stop QualityRecticelPrintService
|
||||
sc delete QualityRecticelPrintService
|
||||
|
||||
# Remove files (optional)
|
||||
rmdir /s "C:\Program Files\QualityRecticel"
|
||||
```
|
||||
|
||||
## Advantages of Native Solution
|
||||
|
||||
✅ **Zero Dependencies**: No Python, Flask, or external packages required
|
||||
✅ **Faster Installation**: No package downloads or environment setup
|
||||
✅ **Better Integration**: Native Windows service with proper lifecycle management
|
||||
✅ **Smaller Footprint**: Minimal disk space and memory usage

|
||||
✅ **Easier Deployment**: Single installer with no prerequisites
|
||||
|
||||
## Development Notes
|
||||
|
||||
### PowerShell Service Implementation
|
||||
The service uses PowerShell's built-in capabilities:
|
||||
- `System.Net.HttpListener` for HTTP server functionality
|
||||
- `Get-WmiObject Win32_Printer` for printer enumeration
|
||||
- `System.Net.WebClient` for PDF downloads
|
||||
- Native Windows service architecture
|
||||
|
||||
### Why PowerShell vs Python?
|
||||
- **Deployment**: No need to install Python runtime or pip packages
|
||||
- **Security**: Uses only Microsoft-signed components
|
||||
- **Performance**: Faster startup and lower memory usage
|
||||
- **Maintenance**: Easier to troubleshoot with native Windows tools
|
||||
- **Enterprise**: Better compliance with corporate security policies
|
||||
|
||||

==================================
|
||||
|
||||
Installation:
|
||||
1. Install the Windows Print Service using install_service.bat
|
||||
2. Install this Chrome extension
|
||||
3. Configure your application to use localhost:8765
|
||||
|
||||
API Endpoints:
|
||||
• http://localhost:8765/health - Service health check
|
||||
• http://localhost:8765/print/pdf - Print PDF files
|
||||
• http://localhost:8765/print/silent - Silent printing
|
||||
• http://localhost:8765/printers - Get available printers
|
||||
|
||||
Troubleshooting:
|
||||
• Ensure Windows service is running
|
||||
• Check firewall settings (port 8765)
|
||||
• Verify Chrome extension permissions
|
||||
• Check service logs: print_service.log
|
||||
|
||||
For support, contact the Quality Recticel development team.
