How to get the paper status of my Thermal Printer using python-escpos?

Question

Currently, I am developing an ordering system that uses a thermal printer.

my code looks like this.

from escpos.printer import Usb
p = Usb(idVendor=0x471, idProduct= 0x55,in_ep=0x82, out_ep=0x02)

try:
    p.text('Hello +\n')
    status = p.paper_status()
    # status = p._read()
    print(status)
    p.cut()

except Exception as e:
    print('error', e)

p.close()

I get the output

: error [Errno 110] Operation timed out

what am I doing wrong?

I also used the python-escpos library to get the paper status at first, but I always got an error, when I used the pySerial library to get the paper status, I found it works! I recommend you to use the pySerial library.
Here are some simple examples:

import serial

# connect your serial port
serialPort = serial.Serial(
    port="COM2",
    baudrate=115200,
    bytesize=8,
    parity="N", 
    stopbits=1,
    timeout=1.00)

# Write a ESC/POS command to get the paper status
get_paper_roll_sensor_status= serialPort.write(b'\x10\x04\x04')

# Read the returned hexadecimal
paper_status = serialPort.read().hex()

# Print according to the hexadecimal value returned by the printer
if paper_status == "12":
    print('Paper adequate')
elif paper_status == "1e":
    print('Paper near-end is detected by the paper roll near-end sensor')
elif paper_status == "72":
    print('Paper roll end detected by paper roll sensor')
elif paper_status == "7e":
    print('Both sensors detect that the printer is out of paper')
else:
    print('other unset values')

You can refer to here, the example I wrote before.
