Printer Model No. : HP Deskjet Ink Advantage Ultra 4729 All-in-One Printer
I use my mobile internet to connect to the printer. I take printouts via phone (Android) and printouts & scan via Android Tablet using the same mobile phone internet connection (I've also installed the HP Printer Service Plugin & HP Smart apps installed in the Tablet).
And, recently I changed my mobile phone from Redmi to Vivo. And surprisingly I couldn't connect my Tablet anymore, nevertheless, I could take printouts via my new Vivo phone.
Please help me out by giving support/guidance in this issue.
