SMIT complains that some required software is not present on the system.
It turns out that this software, "printers.hpJetDirect.attach (18.104.22.168)"
is on the installation CD.
HOWEVER, there is some bug somewhere, whereby the software may actually
be already installed, but the system cannot see it. (Or maybe the bug
is that the software is actually NOT installed, but the system in one
place thinks it is! - I'm not sure). Therefore, use smit to look at
Installed Software ("Software Installation and Maintenance", "Maintain
Installed Software", "List Installed Software" and look at all software,
then search through for "jet". If it finds it (i.e. it thinks that it
is installed) - you must remove it (under smit's "Maintain Installed
Software" level), and then reinstall from the CD!
