Hi

I have changed the buffer_obj type from PyObject to PyByteArrayObject and now it works.

static PyObject *
Connection_writeRequestData (Connection *self, PyObject *args, PyObject *kwds)
{
  static char *kwlist[] = { "buffer", "length", NULL };
  PyByteArrayObject *buffer_obj;
  char *buffer;             /* string from python */
  char *data;               /* data to send */
  int length;
  http_status_t status;         /* Write status */

  if (!PyArg_ParseTupleAndKeywords (args, kwds, "Oi", kwlist,
                                    &buffer_obj, &length))
    return NULL;

  /*
   * Assign result to buffer
   */

  buffer = PyBytes_AsString ((PyObject*)buffer_obj);

  /*
   * Allocate memory and duplicate buffer
   */

  data = (char *) malloc((size_t) length);

  if (data == NULL)
    return NULL;

  memcpy (data, buffer, length);

  debugprintf ("-> Connection_writeRequestData(length=%d)\n", length);

  Connection_begin_allow_threads (self);
  status = cupsWriteRequestData(self->http, data, length);
  Connection_end_allow_threads (self);

  if (status != HTTP_CONTINUE)
  {
    free (data);
    set_ipp_error (cupsLastError (), cupsLastErrorString ());
    debugprintf ("<- Connection_writeRequestData() = NULL\n");
    return NULL;
  }

  free (data);
  debugprintf ("<- Connection_writeRequestData() = %d\n", status);
#if PY_MAJOR_VERSION >= 3
  return PyLong_FromLong (status);
#else
  return PyInt_FromLong (status);
#endif
}

I hope this change is good for you, I have a poor experience with python c binding.

Thanks

Francesco
