You may be able, in the same way, to use the address localhost:631 in a Browser window on the iBook to talk directly to CUPS and get a test page. If that does not work, it may be that CUPS was not fully implemented in that version of Mac OS X.
There is not a Print Utility in the works, but the one Jan Hedlund pointed out has exactly the capabilities he said -- it can turn on the test page that will print the page count, or it can report the page count (in the Utility). But this printer prints so slowly, it cannot have printed a deadly amount of pages even if someone was pushing it fairly hard.
The add-ons (software) you mentioned, Grant, are for the host/print server and are NOT for the client?
Yes, they are for the host computer. They interpret AirPrint print streams from the client and and change them into regular print streams and send it on the the regular printer.
Your Network should be medium-agnostic. By that I mean it does not care whether data are presented over Ethernet or Wi-Fi, if it is from the same network, it is good. AirPrint does not require direct access to Wi-Fi -- it is printing to the existing devices that are reachable on your local network. You are NOT talking directly to these Printers, you are talking to your Router (through any medium) which is connected to the printer, possibly by Wi-FI, but Wi-Fi is not required. An AirPrint Printer can be connected to a Mac via only USB, and still be reachable from your iPhone.
The device you mentioned is a specialized device for something, but I am not quite sure what. You would be better served by getting a "regular" Dual-band Router, and you can connect your existing Ethernet gear directly to it with a single Ethernet cable.
Also, your current Mac can act as a primitive Wi-Fi gateway through Internet Sharing, so you can fiddle around with this before you buy anything.
