I have an Airport Extreme Base Station, and after experimenting with CUPS and consulting several Linux-related websites, I was unable to figure out how to share an HP LaserJet 1200 with my T60 under OpenBSD.
In the end, I decided that it's best not to share a printer over a wireless network, since the printer connection is only weakly encrypted (with WEP). I now use a USB cable and lpd to do my printing.
