+
+## Printer Setup
+
+### Check Available Printers
+```bash
+lpstat -p -d
+```
+
+### Add a Printer (if needed)
+```bash
+# Use CUPS web interface
+http://localhost:631
+```
+
+### Common Printer Names
+- `PDF` - Virtual PDF printer (for testing)
+- `Brother_HL_L2350DW` - Brother laser printer
+- `Canon_PIXMA` - Canon printer
+- Check your system for exact name
+
+## Troubleshooting
+
+### "No Printers Found"
+```bash
+# Start CUPS service
+sudo systemctl start cups
+
+# Check status
+sudo systemctl status cups
+
+# List printers
+lpstat -p -d
+```
+
+### Preview Not Updating
+- Check Python console for errors
+- Verify all dependencies installed: `pip list | grep -E 'kivy|barcode|pillow'`
+- Try restarting the application
+
+### Print Fails
+```bash
+# Test print command manually
+echo "test" | lp -d PDF
+
+# Check printer status
+lpstat -p -l
+```
+
+### Kivy Window Issues
+- If window doesn't open, check X11 display:
+  ```bash
+  echo $DISPLAY
+  ```
+- Resize window manually if elements overlap
+
+## File Guide
+
+- **label_printer_gui.py** - Main GUI application
+- **print_label.py** - Core printing functions
+- **setup_and_run.py** - Automatic setup script
+- **start_gui.sh** - Bash launcher script
+- **requirements_gui.txt** - Python dependencies
+- **README_GUI.md** - Complete documentation
+
+## Tips & Tricks
+
+1. **Fast Printing:**
+   - Preset SAP number as most common value
+   - Just change quantity/ID for each label
+
+2. **Batch Printing:**
+   - Print one label at a time
+   - Small UI makes it quick
+
+3. **Testing:**
+   - Use "PDF" printer to save test labels
+   - Check output files to verify format
+
+4. **Keyboard:**
+   - Tab between fields
+   - Enter in printer dropdown to confirm selection
+   - Alt+P might activate Print button (Kivy dependent)
+
+## Next Steps
+
+- **Learn More:** See [README_GUI.md](README_GUI.md)
+- **Customize:** Modify `label_printer_gui.py` for your needs
+- **Integrate:** Use functions in other Python applications
+- **Support:** Check console output for detailed error messages

+
+## Installation
+
+### Prerequisites
+- Python 3.7 or higher
+- CUPS (Common Unix Printing System) - usually pre-installed on Linux
+- System printer configured and installed
+
+### Setup Steps
+
+1. **Install dependencies:**
+```bash
+pip install -r requirements_gui.txt
+```
+
+2. **Install Kivy garden dependencies** (if using matplotlib preview):
+```bash
+garden install matplotlib
+```
+
+3. **Ensure system printer is configured:**
+```bash
+# Check available printers
+lpstat -p -d
+
+# Or using CUPS web interface
+# Open: http://localhost:631
+```
+
+## Usage
+
+### Run the GUI Application
+
+```bash
+python label_printer_gui.py
+```
+
+### Operation
+
+1. **Enter Label Data:**
+   - Type the SAP Number in the first field
+   - Enter the quantity (numbers only)
+   - Enter the Cable Reel ID
+
+2. **Monitor Preview:**
+   - The preview updates automatically as you type
+   - Shows combined barcode with all entered data
+
+3. **Select Printer:**
+   - Use the dropdown to select your target printer
+   - Default is "PDF" if no other printers available
+
+4. **Print:**
+   - Click "PRINT LABEL" button
+   - Wait for confirmation message
+   - Label will print to selected printer
+
+## Label Format
+
+The label contains:
+- **Row 1:** SAP Number | Quantity | Cable ID (combined in barcode)
+- **Barcode:** Code128 format encoding the combined information
+- **Size:** 11.5 cm width × 8 cm height
+- **DPI:** 300 DPI for high-quality printing
+
+## File Structure
+
+```
+/srv/Label-design/
+├── print_label.py           # Core printing functions
+├── label_printer_gui.py      # Kivy GUI application
+├── requirements.txt          # Original dependencies
+├── requirements_gui.txt      # GUI-specific dependencies
+└── how_to.txt               # Original documentation
+```
+
+## Troubleshooting
+
+### No printers detected
+- Check CUPS service: `sudo systemctl status cups`
+- List printers: `lpstat -p`
+- Restart CUPS if needed: `sudo systemctl restart cups`
+
+### Preview not updating
+- Ensure all input fields are properly connected
+- Check console for error messages
+- Verify PIL/Pillow installation: `python -c "from PIL import Image; print('OK')"`
+
+### Print fails
+- Verify printer name is correct
+- Check printer status: `lpstat -p -d`
+- Test direct print: `echo "test" | lp -d printername`
+- Ensure CUPS daemon is running
+
+### Kivy window sizing issues
+- The app defaults to 1600×900 window
+- Can be resized freely after launch
+- Modify `Window.size = (1600, 900)` in code to change default
+
+## Code Integration
+
+To integrate the printing function into other applications:
+
+```python
+from print_label import print_label_standalone
+
+# Print a label
+success = print_label_standalone(
+    value="YOUR_TEXT",
+    printer="printername", 
+    preview=0  # 0=no preview, 1-3=3s preview, >3=5s preview
+)
+```
+
+## Requirements
+
+- **kivy**: GUI framework
+- **python-barcode**: Barcode generation
+- **pillow**: Image processing
+- **pycups**: CUPS printer interface
+- **matplotlib**: (Optional) For advanced visualization
+
+## License
+
+Based on the existing print_label.py printing framework.
+
+## Notes
+
+- All data is combined into a single barcode for easy scanning
+- Labels are printed at 300 DPI for sharp quality
+- Temporary files are cleaned up automatically
+- Printing happens in background threads to prevent UI blocking
+
+## Support
+
+For issues or questions, check:
+1. Console output for error messages
+2. CUPS printer configuration
+3. System printer availability
+4. Required dependencies installation

+| `show_popup()` | Display notifications |
+
+**Event Flow:**
+
+1. **Initialization:**
+   ```
+   __init__() → get_available_printers()
+                → build()
+                → create_input_column()
+                → create_preview_column()
+   ```
+
+2. **User Interaction:**
+   ```
+   TextInput.on_text → on_input_change()
+                    → preview_widget.update_preview()
+   ```
+
+3. **Printing:**
+   ```
+   Button.on_press → print_label()
+                   → threading.Thread(print_thread)
+                   → print_label_standalone()
+                   → show_popup()
+   ```
+
+## Integration with print_label.py
+
+### Functions Used
+
+```python
+from print_label import create_label_image, print_label_standalone
+```
+
+**create_label_image(text)**
+- Input: Combined text (e.g., "SAP123|50|REEL001")
+- Output: PIL Image (11.5cm × 8cm @ 300 DPI)
+- Generates Code128 barcode
+- Centers text below barcode
+
+**print_label_standalone(value, printer, preview)**
+- Input:
+  - `value`: Text to encode in barcode
+  - `printer`: CUPS printer name (e.g., "PDF")
+  - `preview`: 0=no preview, 1-3=3s, >3=5s
+- Output: Boolean (True=success)
+- Handles CUPS printing
+- Manages temporary files
+
+## UI Layout Structure
+
+### Main Layout
+```
+BoxLayout (horizontal)
+├── Left Column (40%)
+│   BoxLayout (vertical)
+│   ├── Title Label
+│   ├── ScrollView
+│   │   └── GridLayout (1 col)
+│   │       ├── Label: "SAP-Nr. Articol"
+│   │       ├── TextInput (sap_input)
+│   │       ├── Label: "Cantitate"
+│   │       ├── TextInput (qty_input)
+│   │       ├── Label: "ID rola cablu"
+│   │       ├── TextInput (cable_id_input)
+│   │       ├── Label: "Select Printer"
+│   │       └── Spinner (printer_spinner)
+│   └── Button: "PRINT LABEL"
+│
+└── Right Column (60%)
+    BoxLayout (vertical)
+    ├── Title Label
+    └── LabelPreviewWidget
+```
+
+### Styling
+
+**Colors:**
+- Print Button: `(0.2, 0.6, 0.2, 1)` - Green
+- Background: Default Kivy theme
+- Text: Black on white/gray
+
+**Fonts:**
+- Title: 18sp, bold
+- Labels: 14sp, regular
+- Input: 16sp, regular
+
+**Sizing:**
+- Window: 1600×900 (adjustable)
+- Left column: 40% of width
+- Right column: 60% of width
+
+## Threading Model
+
+### Background Printing
+
+```python
+def print_label(self, instance):
+    # ... validation ...
+    
+    popup = Popup(...)  # Show loading
+    popup.open()
+    
+    def print_thread():
+        try:
+            success = print_label_standalone(...)
+            # Update UI in main thread
+            popup.dismiss()
+            self.show_popup(...)
+        except Exception as e:
+            # Error handling
+            self.show_popup("Error", str(e))
+    
+    thread = threading.Thread(target=print_thread)
+    thread.daemon = True
+    thread.start()
+```
+
+**Why threading?**
+- Prevents UI freezing during print
+- CUPS operations can be slow
+- User can continue working while printing
+
+## Error Handling
+
+### Validation
+
+1. **Input Validation:**
+   ```python
+   if not sap_nr and not quantity and not cable_id:
+       show_popup("Error", "Please enter at least one field")
+   ```
+
+2. **Printer Validation:**
+   - Fallback to "PDF" if none available
+   - Checks printer existence before print
+
+3. **Exception Handling:**
+   - Try-except in preview generation
+   - Try-except in print thread
+   - User-friendly error messages
+
+### Logging
+
+- Console output for debugging
+- Error messages in popups
+- Exception info in thread callbacks
+
+## Performance Considerations
+
+### Preview Updates
+
+- Only regenerates label when text changes
+- Debouncing happens naturally via Kivy events
+- PIL image operations are fast (~100ms)
+
+### Memory Management
+
+- Temporary files auto-deleted
+- PIL images cached during preview
+- Temp preview file cleaned when updated
+
+### CUPS Operations
+
+- Non-blocking via threading
+- Timeout handling for printer ops
+- Connection pooled by pycups
+
+## Customization Guide
+
+### Change Label Size
+
+In `print_label.py`:
+```python
+# Modify label dimensions
+label_width = 1063   # pixels for 9cm @ 300 DPI
+label_height = 591   # pixels for 5cm @ 300 DPI
+```
+
+For 11.5cm × 8cm @ 300 DPI:
+```python
+label_width = 1378   # 11.5cm @ 300 DPI
+label_height = 944   # 8cm @ 300 DPI
+```
+
+### Modify UI Colors
+
+In `label_printer_gui.py`:
+```python
+# Change print button color
+Button(
+    ...
+    background_color=(R, G, B, A),  # RGBA: 0.0-1.0
+    ...
+)
+```
+
+### Add New Input Fields
+
+```python
+# In create_input_column():
+new_label = Label(text='New Field:', size_hint_y=None, height=40)
+form_layout.add_widget(new_label)
+
+self.new_input = TextInput(...)
+self.new_input.bind(text=self.on_input_change)
+form_layout.add_widget(self.new_input)
+
+# In on_input_change():
+new_field = self.new_input.text
+```
+
