[Python] Printing Image with brother_ql library in Python on Windows 11: Operation not...

I am trying to print an image on a Brother QL-560 using brother_ql lib in python on Windows 11.

My code looks like this:

from PIL import Image
from brother_ql.conversion import convert
from brother_ql.backends.helpers import send, discover
from brother_ql.raster import BrotherQLRaster
import logging

logging.basicConfig(level=logging.DEBUG)

image = Image.open(r'.\screenshot.png')
size = (720, 1008)
image = image.resize(size)

backend = 'pyusb'
#find printer
#print(discover(backend))
printer = 'usb://0x04f9:0x2027'
model = 'QL-560'

qlr = BrotherQLRaster(model)
qlr.exception_on_warning = True

instructions = convert(
qlr=qlr,
images=[image],
label='62',
rotate='90', # 'Auto', '0', '90', '270'
threshold=70.0, # Black and white threshold in percent.
dither=False,
compress=False,
dpi_600=False,
hq=True,
cut=True
)

send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True)



And it returns the following error:

deprecation warning: brother_ql.devicedependent is deprecated and will be removed in a future release
WARNING:brother_ql.conversion:Need to resize the image...

What am I missing? Are my drivers not compatible?

I have installed libusb-1.0.20 and added MS64/dll to PATH variable and copied libusb-1.0.dll to System32. My Brother QL-560 has all necessary drivers and is working flawlessly with P-Touch Editor.
