We have a customer sending us a PNG file in Base64.  This image is the entire label.  I need to print it with ZPL on a ZE5x1 printer.  I'm new at this and need help with this.  Has anyone done this and can help?

You can use the Link-OS® Multiplatform SDK to connect to the ZE5x1 printer, then call the GraphicUtil.printImage() API to print the PNG on the label.

I cannot use the Geometry Lite Link-OS® Multiplatform SDK to connect to the ZE5x1. Can you provide detailed instructions?

Example using pillow and zplgrf (a Python library for converting images to ZPL):

from PIL import Image
import zplgrf

# Open the image
image = Image.open("label.png")

# Convert to monochrome (1-bit pixels, black and white)
image = image.convert("1")

# Generate ZPL
zpl = zplgrf.image_to_zpl(image)

# Save ZPL to a file or send it directly to the printer
with open("label.zpl", "w") as file:
   file.write(zpl)
