Where HP setup begins, and the one decision to think about first
HP's genuine setup address is 123.hp.com/setup, which hands you the HP Smart app for your operating system. Type it into the browser bar yourself instead of clicking a search result, because that exact string is heavily copied by lookalike sites that charge for software HP gives away and print a support phone number on the page. Then read the screens carefully, because setup may offer to enrol the printer in HP+. That decision is difficult to undo and it commits the printer to genuine HP cartridges and a permanent internet connection, so don't click through it on autopilot. If you want the option of third-party ink later, or the printer will live somewhere with unreliable internet, think hard before accepting.
