Here ist the Answer from HP Support. They responded: There ist no
possibility to get the Driver Package.That's very sad and tells my, that
HP is not interested in Business Costumers using Apple Computers.So it
seems to be time to say bye bye to HP......
I'm just coming from a phone call with HP Support. They will escalate
this to 2nd level of the Software Development. If there comes nothing
usable, this means to me, that we will have to say bye bye to HP.
