Factory Reset for HP Photosmart C4780

HP Photosmart C4780
Mac OS X 10.10 Yosemite

I recently started using a new wireless router after a move, and I am no longer able to get my computer and my printer on the same network.

 

I have been trying to figure out how to change the network that the printer connects to, but I have been completely unsuccessful. I have done a lot of searching around, and nothing seems to work. For what it's worth, I have got all the latest printer and driver software through the Software Update feature on my Mac. I am also able to connect to the printer and print using a USB cable. But I am completely unable to access any settings on the printer that would allow me to switch the printer to the same network as the computer. If anyone has any suggestions on doing that, please let me know.

 

I am thinking that if I could get the printer to do a factory reset, or a hard reset, then that might be a better place to start. I think the printer has some retained memory of the old wireless network, because that network name pops up on one of those troubleshooting pages you can print out. But maybe if the printer had no recollection of any wireless network, then it would be easier to set it up on the new wireless network. Unfortunately, I can't find any information on how to do a factory reset either, so if anyone knows how to do that, please also let me know.
