How do I set up my HP DeskJet 3700 printer wirelessly?

To set up wireless printing, go to 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). You can also press and hold the Wireless and Cancel buttons at the same time for a few seconds until the Power button and blue wireless light start blinking, then the printer is ready to connect to your network.
