How can I print wirelessly without a router using the HP Envy 5530?

You can use HP Wireless Direct to print wirelessly without a router from your computer, smartphone, or other wireless-enabled device. To enable it, touch the Wireless Direct button on the printer's Home screen and select 'On (No Security)' or 'On (With Security)'.
