Printing to a Ricoh 2018 via Appletalk

I'm having trouble getting a Ricoh 2018 to print via Appletalk.

My network looks like this:

I have a Netcomm ADSL modem with 4 built in ethernet ports. I have an Airport Extreme connected to one port, through which I connect my MacBook Pro. I have the printer connected to one of the other ethernet ports.

I have the printer ethernet interface configured to use Appletalk.

When I try and add the printer, it doesn't show up on the first screen, or when I select additional printers and select appletalk, it does not show up there either.

when i check my airport connection in network setup, it shows appletalk enabled, but does not show a zone - this is grayed out and empty.

the area in the printer setup for Appletalk shows "Local Appletalk Zone".

Do i need to create a "local" zone, or am i missing something here?

The printer has previously worked with my old PowerBook G4 running Panther, and an airport express.

Any ideas?

thanks
