HP PHOTOsmart C4780 priming from Apple IOS

[Caprica-7_0]

I previously used up to October 2018 HP SMart App to print via WiFi connectivity from my Apple device. However it is no longer working and I have deleted and reloaded the app with no success. I checked HP site and now it appears that C4700 series is no longer compatible with IOS via AirPrint OR HP Smart. . Anyone else with this problem or is an HP Tech support available to advise how best to resolve. Thanks

A warm welcome to HP Forums! This is a great place to get support, find answers and tips to your technical queries.
As per the HP Mobile Printing Compatibility list available here, HP Photosmart C4700 All-in-One Printer Series does not support HP Smart App or AirPrint. Since for some reason HP Smart App was working before with this model, we might be able to make it work by performing the steps below:

1.) Remove HP Smart App from your iOS device.

2.) Use the steps available here to update iOS.

3.) Turn off your iOS device, Printer and Router.

4.) Unplug the power from the back of router, wait for 10 -15 seconds.

5.) Connect the power cable back to router, turn on the router first. Wait till the router to initialize.

6.) Turn on Printer and iOS device

7.) Download and install HP Smart App from here. 

Let me know how it goes!
