- Remove find_ghostscript() and print_pdf_with_ghostscript() from print_label.py - SumatraPDF is now the primary print method with -print-settings noscale - Fix SumatraPDF arg order: file_path moved to last position - Add -appdata-dir so SumatraPDF reads conf/SumatraPDF-settings.txt (PrintScale=noscale) - win32api ShellExecute kept as last-resort fallback - Remove GhostScript bundling from LabelPrinter.spec and build_exe.py - Add conf/ folder pre-flight check to build_exe.py - Rebuild dist/LabelPrinter.exe (41 MB, SumatraPDF-only)

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
|
|
|
|
Printing method
|
|
---------------
|
|
SumatraPDF is bundled inside the exe and used for all printing.
|
|
It sends the PDF at its exact 35x25 mm page size via -print-settings noscale.
|
|
No GhostScript installation required on the build or target machine.
