iMac+MacBookPro+printer+Time Capsule

[MowingDevil]

So right now I have both an iMac & MBPro connected to my TC via AirPort. I also have a printer connected to the USB port of the TC so I can print from my laptop. Here's the thing, I'd prefer to have the iMac connected via ethernet so that the MBP is the only machine using the wireless network. Is that possible and still have the iMac be able to use the printer which is only connected by the wireless network (through the TC) or would it have to have the iMac's AirPort turned on?

I think your iMac should be able to see the wifi printer even though its hooked up via Gigabit. The TC will bridge them.

Well so far no good...but maybe thats because I have 10.4 on my iMac.
Does anyone know if the DVD that came w/ the MBP can be used to update another computer (say an iMac) to Leopard or is that disc specific to the MBP only? I'm planning on buying Snow Leopard for it in Sept so I don't want to shell out the dough for Leopard to use for basically one month.
