+# Building LabelPrinter.exe on Windows
+
+This guide explains how to build a standalone `LabelPrinter.exe` single-file executable on a Windows machine.
+
+## Prerequisites
+
+1. **Python 3.10, 3.11, 3.12, or 3.13** - Download from https://www.python.org/
+   - ⚠️ **IMPORTANT**: Check "Add Python to PATH" during installation
+   - ⚠️ **Note**: Python 3.14+ may have compatibility issues with Kivy 2.2.1
+   - Verify: Open Command Prompt and type `python --version`
+
+2. **Git** (optional, for cloning the repository)
+
+3. **Internet connection** - To download dependencies
+
+## Quick Start (Using Provided Scripts)
+
+### Option 1: Batch Script (Recommended for CMD users)
+
+1. Open **Command Prompt** (cmd.exe)
+2. Navigate to the project folder:
+   ```
+   cd C:\path\to\label_print
+   ```
+3. Run the build script:
+   ```
+   build_windows.bat
+   ```
+4. Wait 5-15 minutes for the build to complete
+5. The executable will be in: `dist\LabelPrinter.exe`
+
+### Option 2: PowerShell Script
+
+1. Open **PowerShell** (as Administrator recommended)
+2. Navigate to the project folder:
+   ```
+   cd C:\path\to\label_print
+   ```
+3. Allow script execution (if needed):
+   ```
+   Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+   ```
+4. Run the build script:
+   ```
+   .\build_windows.ps1
+   ```
+5. Wait 5-15 minutes for the build to complete
+6. The executable will be in: `dist\LabelPrinter.exe`
+
+## Manual Build Steps
+
+If you prefer to run commands manually:
+
+### Step 1: Prepare Python Environment
+
+```bash
+# Upgrade pip, setuptools, and wheel
+python -m pip install --upgrade pip setuptools wheel
+```
+
+### Step 2: Install Dependencies
+
+```bash
+# Install required Python packages
+pip install python-barcode pillow reportlab kivy==2.2.1 pyinstaller==6.1.0
+```
+
+### Step 3: Build the Executable
+
+```bash
+# Create single-file executable
+pyinstaller label_printer_gui.py ^
+    --onefile ^
+    --windowed ^
+    --name=LabelPrinter ^
+    --distpath=./dist ^
+    --workpath=./build ^
+    --hidden-import=kivy ^
+    --hidden-import=PIL ^
+    --hidden-import=barcode ^
+    --hidden-import=reportlab ^
+    --hidden-import=print_label ^
+    --hidden-import=print_label_pdf ^
+    -y
+```
+
+The build process will take 5-15 minutes depending on your PC speed.
+
+### Step 4: Test the Executable
+
+```bash
+# Run the built executable
+dist\LabelPrinter.exe
+```
+
+## Output
+
+After successful build, you'll have:
+
+```
+dist/
+└── LabelPrinter.exe          ← Single executable file
+```
+
+## Distributing the Executable
+
+You can:
+1. **Copy `LabelPrinter.exe`** to any Windows PC (no Python needed!)
+2. **Share via USB** or file transfer
+3. **Create an installer** using NSIS or InnoSetup (optional)
+4. **Upload to GitHub Releases** for public distribution
+
+## Troubleshooting
+
+### Error: "Python is not recognized"
+- Reinstall Python and check "Add Python to PATH"
+- Restart Command Prompt after reinstalling Python
+
+### Error: "pip command not found"
+- Use `python -m pip` instead of `pip`
+
+### Build takes too long (>30 minutes)
+- **Normal for first build** - Kivy framework is large
+- Subsequent builds will be faster due to caching
+- Close other applications to free up RAM
+
+### Error: "No module named 'kivy'"
+- Make sure dependencies installed correctly: `pip install kivy==2.2.1`
+- Check internet connection
+
+### Python 3.14 Compatibility Issues
+If you have Python 3.14 installed and get errors like:
+- `ModuleNotFoundError: No module named 'kivy'`
+- `ImportError: DLL load failed`
+- PyInstaller compatibility errors
+
+**Solution:**
+- Install Python 3.11, 3.12, or 3.13 instead
+- Download from: https://www.python.org/downloads/
+- Uninstall Python 3.14 first
+- Then use one of the recommended versions
+- Make sure all files are in the project folder:
+  - `label_printer_gui.py`
+  - `print_label.py`
+  - `print_label_pdf.py`
+- Antivirus might be blocking it - check security software
+
+## Build Time Reference
+
+- **First build**: 10-15 minutes (downloading dependencies)
+- **Subsequent builds**: 5-10 minutes (cached dependencies)
+
+## Advanced Options
+
+### Reduce Build Time
+```bash
+pyinstaller label_printer_gui.py --onefile --windowed --name=LabelPrinter -y
+```
+
+### Add Icon to Executable
+```bash
+pyinstaller label_printer_gui.py --onefile --windowed --name=LabelPrinter --icon=path\to\icon.ico -y
+```
+
+### Faster: Use --onedir (Directory) instead of --onefile
+```bash
+pyinstaller label_printer_gui.py --onedir --windowed --name=LabelPrinter -y
+# Builds in ~3-5 minutes, but creates a folder instead of single file
+```
+
+## Support
+
+If you encounter issues:
+1. Check the error message carefully
+2. Make sure Python 3.10+ is installed
+3. Verify all dependencies: `pip list`
+4. Check internet connection
+5. Try again with a fresh Command Prompt window

+# Label Printer - Portable Deployment Guide
+
+## Deployment Structure
+
+The app is now **fully self-contained** with SumatraPDF embedded inside:
+
+```
+LabelPrinter/
+├── LabelPrinter.exe          # Main application (includes SumatraPDF inside)
+├── pdf_backup/               # Auto-created: PDF backups
+└── logs/                     # Auto-created: Print logs
+```
+
+**No visible folders!** SumatraPDF is bundled inside LabelPrinter.exe and extracted to a temporary location at runtime.
+
+## Setup Instructions
+
+### 1. Download SumatraPDF (For Building Only)
+
+**This step is only needed when building the app.** SumatraPDF will be embedded inside the executable.
+
+```powershell
+# PowerShell command to download SumatraPDF
+powershell -ExecutionPolicy Bypass -File setup_sumatra.ps1
+```
+
+This downloads SumatraPDF portable (~5 MB) to the `SumatraPDF` folder.
+
+### 2. Build the Application
+
+```powershell
+.\build_windows.ps1
+```
+
+The build script will:
+- Check for SumatraPDF
+- Bundle it inside the executable
+- Create `dist\LabelPrinter.exe` (~80 MB including all dependencies)
+
+### 3. Deploy
+
+**Simply copy `LabelPrinter.exe` to any Windows machine!**
+
+```
+📁 Deployment (any folder)
+└── LabelPrinter.exe  ← Just this one file!
+```
+
+- No installation needed
+- No additional files or folders
+- Double-click to run
+- Works on any Windows 10/11 machine
+
+## Features
+
+- ✅ **Single Executable** - Everything bundled in one .exe file (~80 MB)
+- ✅ **Fully Portable** - No installation needed, no external dependencies
+- ✅ **Silent Printing** - No PDF viewer windows pop up
+- ✅ **Network Printers** - Supports printers from print servers (e.g. `\\server\printer`)
+- ✅ **PDF Backup** - All labels saved to `pdf_backup/` folder
+- ✅ **Print Logging** - CSV logs in `logs/` folder
+- ✅ **SumatraPDF Hidden** - Embedded inside, not visible to users
+
+## Printer Name Display
+
+Network printer names (e.g. `\\filesibiusb05\ZDesigner_ZQ630`) are automatically shortened to 20 characters in the dropdown for better display. The full printer name is used for actual printing.
+
+## Troubleshooting
+
+### Printing Not Working
+
+1. **Check Printer Connection**: Verify printer is online and accessible
+2. **Check PDF Backup**: Labels are always saved to `pdf_backup/` folder even if printing fails
+3. **Check Logs**: View print logs in `logs/` folder for error messages
+4. **Rebuild App**: If you built the app yourself, ensure `setup_sumatra.ps1` was run first to download SumatraPDF before building
+
+### Network Printers Not Showing
+
+- Network printers must be installed/connected on the machine before running the app
+- For print server printers like `\\filesibiusb05\printer`, ensure the share is accessible
+- Run as administrator if printer enumeration fails
+
+## Notes
+
+- First run may be slower (Kivy initialization)
+- PDF backups are auto-deleted after 5 days
+- Log files are auto-deleted after 5 days
+- Supports Python 3.10-3.13 (Python 3.14+ may have issues with Kivy)

+# Building a Standalone EXE with PyInstaller
+
+This guide explains how to create a standalone Windows executable (`.exe`) file that doesn't require Python to be installed.
+
+## Quick Start (Windows)
+
+### Prerequisites
+- Python 3.11+ installed
+- Virtual environment activated
+- All dependencies installed
+
+### One-Command Build
+
+```bash
+# Activate virtual environment
+venv\Scripts\activate
+
+# Build the executable
+python build_exe.py
+```
+
+That's it! Your executable will be in `dist/LabelPrinter.exe`
+
+---
+
+## What Happens During Build
+
+1. **Analyzes your code** - Finds all imported modules
+2. **Collects dependencies** - Bundles Kivy, PIL, barcode, reportlab, etc.
+3. **Creates executable** - Packages everything into one `.exe` file
+4. **Output**: `dist/LabelPrinter.exe` (~150-200 MB)
+
+---
+
+## Detailed Build Instructions
+
+### Step 1: Install PyInstaller
+```bash
+venv\Scripts\activate
+pip install pyinstaller
+```
+
+### Step 2: Build Using Script
+```bash
+python build_exe.py
+```
+
+### Step 3: Alternative Manual Build
+If the script doesn't work, use this command directly:
+
+```bash
+pyinstaller ^
+  --onefile ^
+  --windowed ^
+  --name=LabelPrinter ^
+  --hidden-import=kivy ^
+  --hidden-import=kivy.core.window ^
+  --hidden-import=kivy.core.text ^
+  --hidden-import=kivy.core.image ^
+  --hidden-import=kivy.uix.boxlayout ^
+  --hidden-import=kivy.uix.gridlayout ^
+  --hidden-import=kivy.uix.label ^
+  --hidden-import=kivy.uix.textinput ^
+  --hidden-import=kivy.uix.button ^
+  --hidden-import=kivy.uix.spinner ^
+  --hidden-import=kivy.uix.scrollview ^
+  --hidden-import=kivy.uix.popup ^
+  --hidden-import=kivy.clock ^
+  --hidden-import=kivy.graphics ^
+  --hidden-import=PIL ^
+  --hidden-import=barcode ^
+  --hidden-import=reportlab ^
+  --hidden-import=print_label ^
+  --hidden-import=print_label_pdf ^
+  --collect-all=kivy ^
+  --collect-all=PIL ^
+  label_printer_gui.py
+```
+
+---
+
+## Output Files
+
+After building, you'll have:
+
+```
+Label-design/
+├── dist/
+│   └── LabelPrinter.exe          ← Your standalone executable (150-200 MB)
+├── build/                         ← Temporary build files (can delete)
+└── label_printer.spec             ← PyInstaller spec file
+```
+
+---
+
+## Running the Executable
+
+### On Your Computer
+1. Double-click `dist/LabelPrinter.exe`
+2. App starts immediately (first run takes ~5 seconds)
+3. Works like the Python version
+
+### Sharing with Others
+1. Copy `dist/LabelPrinter.exe` to a folder
+2. Create a shortcut to it on the desktop
+3. Share the folder or executable
+4. **No Python installation needed on their computer!**
+
+### Creating a Shortcut
+1. Right-click `LabelPrinter.exe`
+2. Send to → Desktop (create shortcut)
+3. Double-click the shortcut to run
+
+---
+
+## Troubleshooting
+
+### "Failed to build the executable"
+
+**Solution 1**: Check Python version
+```bash
+python --version  # Should be 3.11+
+```
+
+**Solution 2**: Update PyInstaller
+```bash
+pip install --upgrade pyinstaller
+```
+
+**Solution 3**: Install missing dependencies
+```bash
+pip install -r requirements_windows.txt
+pip install pyinstaller
+```
+
+### "DLL load failed" when running exe
+
+This usually means a library isn't bundled correctly.
+
+**Solution**: Rebuild with verbose output
+```bash
+pyinstaller --debug=imports label_printer_gui.py
+```
+
+### Executable is very large (200+ MB)
+
+This is normal for Kivy applications. The size includes:
+- Python runtime (~50 MB)
+- Kivy framework (~30 MB)
+- Dependencies (PIL, barcode, reportlab, etc.) (~20 MB)
+- Your code (~1 KB)
+
+You can reduce size slightly with:
+```bash
+--exclude-module=matplotlib
+--exclude-module=numpy
+--exclude-module=scipy
+```
+
+### Slow to start (5-10 seconds)
+
+Normal for Kivy apps. The first startup initializes:
+- Python runtime
+- Kivy graphics system
+- Font rendering
+- Window initialization
+
+Subsequent runs are faster (~3 seconds).
+
+---
+
+## Advanced Options
+
+### Add an Icon
+1. Create a 256x256 PNG icon: `app_icon.png`
+2. Convert to ICO: Use an online tool or ImageMagick
+3. Build with icon:
+```bash
+pyinstaller --icon=app_icon.ico label_printer_gui.py
+```
+
+### Two-File Distribution
+Instead of `--onefile`, use separate files for faster startup:
+```bash
+pyinstaller label_printer_gui.py
+```
+Creates `dist/` folder with all files (faster to run, easier to debug).
+
+### Console Output
+To see error messages, remove `--windowed`:
+```bash
+pyinstaller --onefile --name=LabelPrinter label_printer_gui.py
+```
+
+---
+
+## Build Options Reference
+
+| Option | Purpose |
+|--------|---------|
+| `--onefile` | Single executable (recommended) |
+| `--windowed` | No console window |
+| `--icon=file.ico` | Custom icon |
+| `--hidden-import=module` | Include module that's not imported directly |
+| `--collect-all=module` | Include all module data |
+| `--distpath=folder` | Output directory |
+| `--name=AppName` | Executable name |
+
+---
+
+## Final Steps
+
+1. **Test the executable**: Run `LabelPrinter.exe` and test all features
+2. **Verify PDF backup**: Check `pdf_backup/` folder is created
+3. **Test printing**: Print a label to ensure PDF output works
+4. **Share**: Distribute the `.exe` file to users
+
+---
+
+## Questions?
+
+- Check the error message in the console
+- Try rebuilding with `python build_exe.py`
+- Ensure all dependencies are installed: `pip install -r requirements_windows.txt`
+- Check that Python 3.11+ is installed: `python --version`
+
+Good luck! 🚀

+# Label Printer GUI - Windows Setup Guide
+
+## Installation Steps
+
+### 1. Install Python
+- Download Python 3.11+ from [python.org](https://www.python.org/downloads/)
+- **Important**: Check "Add Python to PATH" during installation
+
+### 2. Create Virtual Environment
+```bash
+python -m venv venv
+venv\Scripts\activate
+```
+
+### 3. Install Dependencies
+```bash
+pip install -r requirements_windows.txt
+```
+
+### 4. Optional: Windows Printer Support (pywin32)
+After installing requirements, run:
+```bash
+python -m pip install --upgrade pywin32
+python Scripts/pywin32_postinstall.py -install
+```
+
+This enables native Windows printer detection.
+
+## Running the App
+
+### From Command Prompt
+```bash
+venv\Scripts\activate
+python label_printer_gui.py
+```
+
+### Create Shortcut (Optional)
+Create a batch file `run_app.bat`:
+```batch
+@echo off
+call venv\Scripts\activate.bat
+python label_printer_gui.py
+pause
+```
+
+Then double-click the batch file to run the app.
+
+## Features
+
+✅ **Cross-Platform GUI** - Works on Windows, Linux, and macOS
+✅ **Barcode Generation** - Automatic Code128 barcode creation
+✅ **PDF Output** - High-quality PDF labels stored in `pdf_backup/` folder
+✅ **Printer Support** - Automatic printer detection (Windows, Linux, macOS)
+✅ **Input Validation** - 25-character limit with real-time validation
+✅ **PDF Backup** - All generated labels automatically saved
+
+## Printer Setup
+
+### Windows
+1. Go to Settings → Devices → Printers & Scanners
+2. Add your label printer
+3. Run the app - printer will be auto-detected
+4. Select printer from dropdown
+
+### Alternative (No Printer)
+- Select "PDF" option
+- Labels will be saved to `pdf_backup/` folder
+- Open and print from any PDF viewer
+
+## Troubleshooting
+
+### "No Printers Found"
+- This is normal - select "PDF" option
+- You can print PDFs manually from the backup folder
+- Or install your printer driver
+
+### Windows Defender Warning
+- Click "More info" → "Run anyway"
+- This is safe - the app is open-source
+
+### Missing Dependencies
+```bash
+pip install --upgrade pip
+pip install -r requirements_windows.txt
+```
+
+### Port Already in Use
+If you get an error about ports, restart your computer or:
+```bash
+python -m pip uninstall -y pywin32
+python -m pip install pywin32
+```
+
+## File Structure
+
+```
+Label-design/
+├── label_printer_gui.py      # Main GUI application
+├── print_label.py            # Print functionality
+├── print_label_pdf.py        # PDF generation
+├── requirements_windows.txt  # Windows dependencies
+├── pdf_backup/               # Stored PDF labels
+├── venv/                     # Virtual environment
+└── documentation/            # Documentation files
+```
+
+## Tips
+
+- **Character Limit**: Each field supports up to 25 characters (barcode limit)
+- **Quantity Field**: Only numbers allowed
+- **PDF Backup**: All labels automatically saved with timestamp
+- **Cross-Platform**: Same code runs on Windows, Linux, and macOS
+
+For more information, see the documentation folder.
