After suffering a power outage, our power supply in our Mac G5 doesn't work. We used Migration Assistant to transfer our data from the old hard disk to a new Macpro running Mac OS X 10.5.1. We were originally running Mac OS X 10.4.1. We had to re-activate all our software after the migration, but now I have lost all my other printers and scanners attached as peripherals and I cannot see Adobe pdf 8.0 printer. They do not appear on my printer list or when I go to print from any of my applications.
