HP Photosmart C4780: Can't hook up wireless..Please Help

Question

I just bought a brand new IMAC and a brand new HP Photosmart C4780 wireless printer and a new Linksys WRT160N wireless-NBroadband Router. I go thru all the steps to set up and than get the error message the configuration failed and the software was unable to configure my device. The error message says :
Ip Address: Failed to retrieve IP
Subnet Mask : Failed to retrieve IP
Default Gateway : Failed to retrieve IP
Preferred DNS Server: Failed to retrieve IP
Alternate DNS Server: Failed to retrieveIP
I am clueless where to go from here. Can someone please help.
Thank You
Joe

The Linksys WRT160N has WPS (Wi-Fi Protected Setup).  If you are using WPA-PSK encryption (recommended), then you can easily connect the C4780 to your wireless network using WPS:
1) On the Linksys router, press the WPS button that is top of the case just under the Cisco label.  When the LED on the button starts to blink,  then the WPS process has started.
2) On the C4780 printer:
press the Scan Button
select Wireless Menu
select WPS
select Push Button
The printer should connect. 
Since you have a new iMac running Snow Leopard, then all that is left to do is to install the SW.  Open the Print & Fax applet under System Preferences and press the [+] button.  Highlight your printer and press Add.
