Wireless printing help

[J Langlois]

Hello all, I have a need to print wirelessly at home, but I can't seem 
to connect properly to my printer. I am using the following hardware: 
15' AL with Panther, snow AirPort connected to a D Link DL604 router, 
HP LJ 1200n also connected to the router and all is functioning 
properly (individually). That is to say everything on the network was 
and is working correctly, but I cannot print via AirPort. My print jobs 
just sit forever. I can connect directly to the HP LJ and print, but 
not via the AP. There must be something obvious that I am overlooking. 
Can anyone think this through, I am a bit frustrated and can't see the 
obvious here. Regards J Langlois
