First make sure you are connected to the internet and just insert the CD that came with it to your computer and follow the instructions. Also complete the set up process from the little screen in the printer. Make sure you also set up the wireless feature from the printer by entering your router key-phrase number. After this your computer should detect the printer and continue the set up process.
You need to go to the hp website and follow the instructions from there. Can be a little tricky to get hooked up wireless. I had to return one that was unable to connect. Okay buy for the price. May need to invest in a better one soon.
