Here is response from HP-s support service:
"""
I understand that you need information, whether you can use your
CD-Writer on parallel port with HP-UX 11.00 Operating system and you need compatible
software for creating CDs.
HP does not support the HP CD-Writer parallel port on HP-UX 11.00 Operating systems.
We do not provide any software that is compatible and can be used with HP-UX 11.00. """"
