Welcome to the HP Community.
HP Smart is a nice application - it provides a number of features that require that the printer and the HP account be known to the application. That said, use of HP Smart is not mandatory.
If you have not done so,
Check and Install the Full Feature Software / full driver software.
Your printer software installation package:
HP ENVY Photo 7800 All-in-One Print and Scan Driver and Accessories
===========================================================
>>> Check / Install the Full Feature Software / full driver printer software
The full driver provides the foundation on which other programs and printing software depend.
Preparation - Install Full Driver Printer Software
If you have not done so,
In addition to the HP Smart application,
Install the Full Feature Software / full driver printer software for the printer.
HP Smart and other print software / applications benefit from having the full driver installed.
Make sure your VPN is switched Off when installing software.
Printer Software Check - Is the printer software installed?
Notes
When the full driver printer software is installed,
Find the printer software listed in Control Panel > icon view > Programs and Features.
The installation of the full printer software adds two shortcut icons to the Desktop.
The Printer Assistant is named for the printer and provides access to Print , Scan , and Tools
HP Scan is named for itself and provides a direct call to the HP Scan software.
