I have HP LaserJet P1006 connected to my Macbook via USB which I am trying to share with my PowerMac G4. Both of the computers are on the same network. The PowerMac sees the printer on my macbook, but when I try to print using it, it times out saying it cannot connect to the printer. Any ideas?

Printer sharing is turned on for both computers. I'm not sure what to do.

Both are running Leopard.

Thanks in advance, any help would be appreciated =)
