• Select printer
• Print labels

✅ Use the API

from print_label import print_label_standalone, create_label_image

# Create image
image = create_label_image("DATA_HERE")
image.save("label.png")

# Print directly
print_label_standalone("DATA", "PrinterName", preview=1)

✅ Customize Everything

• UI colors and layout
• Label size and format
• Data fields
• Printing behavior

✅ Integrate with Systems

• Use printing functions in your apps
• Call GUI programmatically
• Extend with new features
