The method that contains your code must have at least the first parameter 'self'::
  def pdfwrite(self):
    R = self.REQUEST.RESPONSE
    R.setHeader('content-type', 'application/rtf')
    R.setHeader('content-length', str(len(data)))
    R.write(data)
It's a way of getting access to context.
OK, thanks. But how can I pass the self parameter using the dtml-call tag? <dtml-call "pdfwrite(self)"> is correct? Because I'm using this and works fine.
It's Python magic. When you call a function/method on an object, the object is provided as the first parameter of the method. This is implicit, I believe, in DTML calls, either expression or name. It's explicit in TALES and Python::
   context/pdfwrite
   context.pdfwrite()
So, I put the code here. Please, what I'm missing? :)


It's easier to guess when you say what the problem is.

I do see some funny indentation down at the bottom.
