How to handle multi-page PDF generation with wkhtmltopdf in PyInstaller?
When generating multi-page PDFs using wkhtmltopdf in PyInstaller, you can follow these steps:
- Ensure that you have included all necessary wkhtmltopdf dependencies and resources in your PyInstaller bundle. This might include fonts, images, stylesheets, etc. You can do this by modifying the PyInstaller spec file or using the --add-data option when running PyInstaller.
