set it up initially with your MBP connected to the Router with an ethernet cable.
Once you have got it printing, remove the cable and try printing again.

I need help in figuring out how to print wirelessly from my Macbook Pro with Snow Leopard (Mac OS X 10.6.5) to my HP Color Laserjet 2600n. I've set up a static IP on the printer and hooked it up to a D-Link router. I see the printer in my system, but printing fails each time. It appears there's a software glitch of some sort.
