I recently purchased a new Airport Extreme Base Station, only to realize afterward that my printer was not listed on Apple's Airport Extreme Printer Compatibility webpage
I was even more disappointed to find sparse documentation inside the base station box for different ways that a printer could be configured through the base station. Fortunately, after plugging in the printer to the base station, the printer was visible in Print Center by setting up a new "Rendezvous" printer.
If your printer works in Jaguar 10.2.3, I'm guessing it will work with the new Airport Extreme Base Stations, even though Apple and its business partners would prefer you buy a new printer. I have an Epson Stylus Photo 750, and it works great, wirelessly now.
[robg adds: I don't have an Extreme unit to test with, so I can't verify this one...]
