"""
PyInstaller build script for Label Printer GUI
Run this to create a standalone Windows executable

IMPORTANT: This script MUST be run on Windows to generate a Windows .exe file.
If run on Linux/macOS, it will create a Linux/macOS binary that won't work on Windows.

To build for Windows:
1. Copy this project to a Windows machine
2. Install dependencies: pip install -r requirements_windows.txt
3. Run this script: python build_exe.py
4. The Windows .exe will be created in the dist/ folder
