I have a new HP all in one printer that is supposed to be wireless but it only prints with a usb cable. help?

I can't figure out how to make it print wireless! because it only detects the printer when it is connected with the cable.

which model is it?
I believe you only need to use the USB cable once, and that's during set up. Best for you is to contact HP If still under warranty call 1-800-474-6836 Or go to their site. Then lower left click Support and troubleshooting Then upper right, contact HP Here you have a choice of email or live chat support (Via computer) They are fast in responding It is free....24/7
