Thanks for reaching out. For assistance printing on the HP Deskjet, please contact HP for assistance in connecting to Hotspot Network.
If you wish to attempt to connect your printer to your wifi hotspot, turn on your hotspot and then go to your printer settings under wifi networks and search for your hotspot and enter the necessary info (device name, password, etc.)
You should have the HP Print App to do this.
Hope this bit of info helps in any way.
