Hi there and welcome
Is the printer connected to the same wifi network as the phone?
Please let me know
Go to the Play Store on the Samsung and download the app HP ePrint
Then open this app and from within this app you can print to the printer.
It all has to be done via this app
If you have any problems or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
