print() writes to the text (unicode) layer of sys.stdout.
If you want to access the binary (bytes) layer, you must use 
sys.stdout.buffer. So:

  sys.stdout.buffer.write(chr(253).encode('latin1'))

or:

  sys.stdout.buffer.write(bytes([253]))

See http://docs.python.org/py3k/library/io.html#io.TextIOBase.buffer
