changing IP address for wireless printer

[-s-c-]

I followed the instructions provided, but when I clicked "apply", I got an error message saying that the Manual Default Gateway option is mandatory. 

How do I get around that?

Kudos to you.  I fixed it, 

Turned off printer and disconnected router;  plugged it back in and turned on printer.  REad the IP and I am working again.

I am able to print just fine using Internet Explorer, however when I use Firefox, I am not able to print.

recently moved and now trying to scan in my new place.  I've got a HP photosmat 7520 all in one.

Can't get it to connect to scan but it does have the capabilites of emailing me a new Pin.

when I print the test it give directions to unplug router, turn on and off printer - wait 60 seconds and try again. 

Done it several times always getting the same result, no wireless connection.  However, I did get one test result saying there was no problems found but as soon as I tried to scan it gave me the same error message.

IP Address 169.254.91 66

Please assist... I'm getting frustrated.

My Imac is using a new wireless router with a different number and my printer is still under the old number. How do I change to the new router home number?

I followed the directions for resetting the IP address for my printer but when I got to the line for the gateway address and left it blank I couldn't continue. I was told it was mandatory. Where do I get the gateway address?
