printing problem - ImportError: No module named utils

Hi,
I am new to linux and have Redhat 7.3 installed.
I would like to use a hpdeskjet 960c printer on the 
parallel port and tried to run printconf-gui but 
I get this traceback:

Traceback (most recent call last):
  File "/usr/sbin/printconf-gui", line 7, in ?
    import printconf_gui
  File "/usr/share/printconf/util/printconf_gui.py", line 41, in ?
    from printconf_conf import *
  File "/usr/share/printconf/util/printconf_conf.py", line 82, in ?
    from xml.utils import qp_xml
ImportError: No module named utils

I already went through the installation instructions on the hp pages
http://hpinkjet.sourceforge.net/install.php
(updating ghostscript, foomatic and the hpijs)
but they do not mention the utils module. 
What am I doing wrong?

Regards
