HP Photosmart C4780 wifi -cannot reset and cannot find printer driver

[pohcbmal]

I have an HPC4780 printer that has always worked with my Macbook OSX 10.9 until I had a new network created.  I can't figure out how to reset the network in the printer.

I tried RESET network defaults but there is no such thing in the menu only RESTORE defaults.  That doesn't work.  So then I thought I'd uninstall my HD software, redownload and start over, but I did not realize I'd need a wifi connection to find the printer driver and reload it!   So now because I did that and there is no wifi connection, my printers & scanners don't even show that the printer exists and cannot find it when I press the + button.  So I have TWO problems.  

I tried unplugging and then reconnecting and resetting wireless but it still does not work.  

Help what can I do?

Hi,

Temporary connect the printer with a USB to your Mac, then follow HP EasyStart below:

https://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Applications/HP_Easy_Start.app.zip

By following the steps on screen you should be provided with an option to configure the printer to your wireless network.

Please let me know of any problem,

Thanks, well your solution helped my printer find the driver and I could print while connected.  But I'm back to my original problem....I cannot find a way to tell it to look for a different wifi network.  I tried redownloading the software drivers but the installation does NOT give me an option to choose wifi. I tried following these directions for USB set up of wireless and it's an endless loop: USB set up page leads to download page which leads back to USB set up page...  The Easy Setup did not do anything either - it does not find the device unless the USB is plugged in, in which case it's not setting up the wi-fi.
