In python code:
typewriter = printer.Usb(0x1d90, 0x20f1, 0, 0x81, 0x2)

What I done:

• already set

udev rule, SUBSYSTEM=="usb", ATTRS{idVendor}=="1d90", ATTRS{idProduct}=="20f1", MODE="0664", GROUP="home"

• reload with sudo udevadm control --reload && sudo udevadm trigger
• restart hardware
• try to search this problem in google for solution but no results to solve.

I do not know how to fix/solve this problem
Please advice/suggest.

best regards

I'm having the same thing. I keep getting usb.core.USBError: [Errno 5] Input/Output Error
I'm using a raspberry pi zero 2 and I'm only trying to print an image and 3 lines of text
Here's my code:

from escpos.printer import Usb

printer = Usb(0x28e9, 0x0289)
printer.image("/home/pi/image.jpg")
printer.text("\n\n\n")
