How do I set up wireless printing on my HP DeskJet 3700?

You can set up wireless printing by visiting 123.hp.com to download and install the HP Smart app or printer software, which will help you connect to your wireless network (2.4 GHz supported). Alternatively, you can press and hold the Wireless and Cancel buttons simultaneously for a few seconds until the Power button and blue wireless light start blinking, then use Wi-Fi Protected Setup (WPS) mode by pressing and holding the Wireless button until it blinks and pressing the WPS button on your router within two minutes.
