Can I print wirelessly without a router using the HP OfficeJet Pro 8720?

Yes, with Wi-Fi Direct you can connect your computer or mobile device (such as a smartphone or tablet) directly to the printer wirelessly without connecting to an existing wireless network. To use Wi-Fi Direct, you might need HP software installed on your computer or mobile device, and for more information you can visit 123.hp.com/ojp8720. (Page 3)
