The HP Setup Assistant is software primarily used for setting up and managing HP devices like printers and computers. It helps configure device connections, update drivers, and access diagnostics and support tools.

More specifically, HP Support Assistant is a free application that usually comes pre-installed on HP computers. It provides automatic updates, diagnostics, troubleshooting, and device management for HP PCs and printers. If not pre-installed, it can be downloaded from HP’s official site (hp.com/go/supportassistant). The installation involves downloading the installer, running it as administrator, agreeing to license terms, and then using the app to keep your HP devices updated and maintained [1][2][3].

For printers, HP Setup Assistant or similar tools help to configure wireless connections and printer setup through utilities often accessible via Windows’ Printers & Scanners settings or dedicated HP software [4]. On Mac or iOS devices, HP offers apps like HP Smart and HP Support Assistant Mobile to assist with printer setup and device support [3][5].

In summary, “HP Setup Assistant” often refers to HP Support Assistant software on computers or utility apps on mobile and desktop platforms designed to help users install, configure, and maintain HP devices effectively.
