The driver setup errors out, hangs, or rolls back before finishing. This usually comes from a leftover old driver, a blocked download, or running the wrong package for your OS.
Work through these in order; most people are fixed by the first two or three.
Uninstall the existing printer software from Apps, then in "Print server properties" (Win+R › printui /s /t2) remove the leftover driver package, and reboot.
Get the full driver/software for your precise model and Windows/macOS version from the manufacturer — not a generic or older build.
Right-click the installer › Run as administrator. Temporarily pause antivirus if it blocks the setup.
For USB installs, don't plug in the printer until the installer tells you to.
