This is a 3.x port for Label Generator in The Post Office Pattern - Stickers Generator extension by cesarhenrique. I updated and tested it on Opencart 3.0.3.8 for personal use. Please support the original developer. All credits to cesarhenrique for making this simple yet useful extension.

Installation & Usage:
1. Go to Installer and upload the extension file.
2. Go to Modifications clear and refresh it.
3. Go to Orders and select an order.
4. Click Print Label button.
