Dear community;

I use Rasbian, I got the phoenix printer 
(http://pyramidacceptors.com/phoenix-printer/) from PTI. I use Rasbian as OS. I 
attach a dump of the details of printer. I used following python code:

from escpos import *
Epson = printer.Usb(0x2504,0x0300)
Epson.text("Hello World")
Epson.cut()

Running this code as root results:

  File "gpio.py", line 5, in <module>
    Epson.text("Hello World")
  File "/usr/local/lib/python2.7/dist-packages/escpos/escpos.py", line 264, in text
    self._raw(text)
  File "/usr/local/lib/python2.7/dist-packages/escpos/printer.py", line 58, in _raw
    self.device.write(self.out_ep, msg, self.interface)
  File "/usr/local/lib/python2.7/dist-packages/usb/core.py", line 625, in write
    fn = fn_map[self._ctx.get_endpoint_type(self, endpoint, intf)]
  File "/usr/local/lib/python2.7/dist-packages/usb/core.py", line 180, in get_endpoint_type
    etype = util.endpoint_type(e.bmAttributes)
AttributeError: 'NoneType' object has no attribute 'bmAttributes'


All the best;
