htmlconfig button doesn't work when setting up wifi printing HP 1102w

I have a Macbook Pro. Mavericks OS.

Printer is a HP P1102w.

The printer works fine via the USB cable but I cannot set up the wireless connection. The blue light flashes and cannot find a network. IP address is just zeros.

I have been following various help guides and get to the point where it says click on HTMLConfig in the System Preferences. However, when I do this instead of getting another popup window and going to the next stage nothing happens and it takes me back to the previous step.

There is a very helpful setup video on YouTube, but like I said, when I click HTMLConfig I don't move on to the next window like the guy in the video does: https://www.youtube.com/watch?v=c972ybZvZzo

I've seen another thread here with the same problem, but that guy just had to reset his printer and it starting working. I have reset my printer but still can't configure wifi.

I initially posted my problem on the HP help site, but they couldn't help and said it is an OS issue.

Why is this button not working?
