im not sure if the original poster meant what is my wpa paassphrase so i can connect my printer to the airport or if the original poster meant how do i access and configure the wpa passphrase in the printer
my hp photosmart, its a 3310 has a webserver so i can set the wpa passphrase there by connecting to it via Ethernet and browsing it, like
http://192.168.1.138
theres also a network configuration page you can print out that should list the wpa passphrse
and lastly at least my hp photosmart can read 'windows connect now' usb drives. so if you have a windows machine and connect it wireless to the base station and save the wireless configuration to a usb drive, u can add the hp printer easily
by inserting the usb flash drive into the printer and it should automatically import the base station id and password to use
so if your printer is newer then a photosmart 3310 then i would imagine windows connect now should work on it
