Picked up a new MBP to go along with our imac. I have airport up and running (took a little while) for internet and itunes using the imac as the base station.

Now to get the printer up and running on both. Its an HP4780.

Does the printer have to be hooked up to the imac via usb? Then the MBP uses it thru airport?

Or can I have both computers use the printer wirelessly?

This is my first wireless network.
