How do I enable Quiet Mode on the HP Envy 6000e?

Quiet Mode can be turned on through the HP Smart app by tapping the printer image on the Home screen and tapping Quiet Mode to change the setting. You can also enable it through the embedded web server (EWS) by clicking the Settings tab, selecting Quiet Mode under the Preferences section, and clicking Apply. Note that Quiet Mode only reduces noise when printing with Better print quality on plain paper — it has no effect when printing in Draft or Best quality, or when printing photos or envelopes.
