Installation Issue of a HP c7280 Photosmart AiO on Windows XP SP2

Hi,
i'm trying to install the AiO Printer for over a week, i get in contact
with the HP support and they gave me some possible solution, but they
don't help me with my problem.

Short description of the problem:
OS: Windows XP SP2
Laptop: Acer 5672 AWLMI with Core Duo (1,73 GHz and 1 GB RAM)

During the installation, when the software starts to create a connection
with the printer over wlan, windows detects an error and closes the
Generic Host Prozessor. This must be the main problem. The driver and
the software is installed but the Computer can't see and find the
printer and i'm not in grade to create the connection manually. After a
restart Windows detects the printer but says that the connection is unknown.
