Question

我尝试在热敏打印机中打印票证。我使用模块escpos

但是当我在Windows中运行脚本时，它向我发送以下错误

Traceback (most recent call last):
      File "C:\Users\Angel\Desktop\Escritorio\impreimer.py", line 5, in <module>
        Epson = printer.Usb(0x1a86,0x7584,1)
      File "C:\Users\Angel\AppData\Local\Programs\Python\Python36\lib\site-packages\escpos\printer.py", line 51, in __init__

        func = self._FuncPtr((name_or_ordinal, self))
    AttributeError: function 'usb_detach_kernel_driver_np' not found
    [Finished in 0.5s with exit code 1]

这是我的代码：

import sys
from escpos import *

pr = printer.Usb(0x1a86,0x7584)

我该如何解决？

找不到escpos错误'usb_detach_kernel_driver_np'
