I am trying to print images on an Epson TM-T81III POS printer using Python ESC/POS and Pillow, and I want to integrate this into an ERPNext Print Format (Jinja).

Here is the Python code that works perfectly :

from escpos.printer import Network
from PIL import Image # pip install Pillow if needed

Connect to printer

kitchen = Network("192.168.68.111", profile="TM-T88III")

Load and resize image (maintain aspect ratio)

img_path = "/Users/mondaysys03/Desktop/image_convert/Frame .png"
img = Image.open(img_path).convert('L') # Grayscale for thermal
img_resized = img.resize((512, int(img.height * 512 / img.width)), Image.Resampling.LANCZOS)
resized_path = img_path + '_resized.png'
img_resized.save(resized_path) # Optional: save resized

Print

kitchen.image(resized_path) # Or use '_resized.png'
kitchen.cut()
kitchen.close()

I want to trigger this printing using Jinja or a server-side script or (esc raw command).
How can i do that?
