+# PORTABLE PYTHON PACKAGE INSTRUCTIONS
+
+To create a complete self-contained package, you need to include a portable Python interpreter.
+
+## Option 1: Download Embedded Python (Recommended)
+1. Download Python 3.11 Embedded from: https://www.python.org/downloads/windows/
+2. Choose "Windows embeddable package (64-bit)" or "(32-bit)" 
+3. Extract to a folder named 'python_portable'
+4. The structure should be:
+   python_portable/
+   ├── python.exe
+   ├── python311.dll (or similar)
+   ├── pythoncom311.dll
+   └── ... (other Python files)
+
+## Option 2: Use PyInstaller (Alternative)
+1. Install PyInstaller: pip install pyinstaller
+2. Run: pyinstaller --onefile --noconsole print_service_complete.py
+3. This creates a single .exe file with all dependencies
+
+## Option 3: Manual Python Installation Check
+The installer will check for system Python and use it if available.
+
+## Current Package Structure
+This package includes:
+✓ Complete Python script with all dependencies
+✓ Windows service installer
+✓ Chrome extension
+✓ Logging and error handling
+✓ Multiple printing method fallbacks
+✓ Automatic recovery options
+
+## Dependencies Included in Python Script:
+- All standard library modules (http.server, json, subprocess, etc.)
+- No external dependencies required
+- Pure Python implementation
+
+The service will work with any Python 3.7+ installation.
