How do I get my iPhone 4s to print using AirPrint

Question

I have a HP LaserJet P1102w printer that has the latest firmware and drivers installed, but I cannot get it to print fom my iPhone 4s.  I am probably doing something wrong that is right in fromt of me.  Both Apple and HP say this printer is AirPrint capable.  I have no problem printing from my MAC Pro Tower.
Any help and/or direction is greatly appreciated.
Thank you

Assuming you answer "Wirelessly" to randers4's question above, can your Mac see the printer?  If so, it's on the network.
Here's an excerpt from your printer's manual in case it helps:
To connect the product to a computer on a wireless network, follow these steps:
Open Finder in the dashboard.
Click Applications, and then double-click System Preferences, and then click Print & Fax.
Open Print Queue, click Printer Setup, click the Utility tab, and then click Open Printer Utility.
Click HTMLConfig.
Click the Networking tab, and then click Wireless in the list on the left.
Under Communication Mode, click Infrastructure, select a network name from the Available Network Names (SSID) list, and then click the << button.
From the Security Mode pop-up menu under Authentication, click WEP.
Type the WEP key and then click Apply.
Click OK in the confirmation box.
Close the HTML Config windows and the Print Queue window.
In the Print & Fax window, choose the USB option (listed with the product model) and then click the minus - button.
When the window with the list of printers appears, choose the Bonjour option (listed with the product model), and then click Add.
