Question

我正在尝试使用python escpos.printer模块打印到打印机，但始终收到此错误NotImplementedError：在此平台上不支持或未实现操作，搜索无济于事，我使用的是Windows 7 64位操作系统。这是escpos.printer的默认代码我也找到了这个答案，但它没有用Pyusb on Windows 7 - NotImplemented Error :is_kernal_driver_active

from escpos.printer import Usb

p = Usb(0x0483,0x5743)
p.text("Hello World\n")
p.image("logo.gif")
p.barcode('1324354657687', 'EAN13', 64, 2, '', '')
p.cut()
