I have a G3 tower currently running OS 9.2.2, and I want to be able to use the printer connected to it from my powerbook which is running 10.4.9. Is there any way to do this? Also I have an external firewire HD that when I plug it in to the tower it says that it is unreadable by the computer, but it works fine plugged into my powerbook. so if anyone can help me with this thanks in advance.
