I have that printer (or one very close to it, the reference number is that or very similar) - it can be a right sod Karen. Great printer when you get it set up.
The most important thing to get your head round is that it is a wireless printer but you really need to install it by connecting to it via USB cable (USB connector is on the left side).
I would say two most important things.
1. If it is installed on another laptop - a Windows 7 one and is still installed, you can try to connect to it via your Windows 8 control panel ( control panel - devices and printers - add a printer - it then searches for all connected and wireless printers.
Hopefully yours will show up as it is already network installed. If it does show up, just proceed with the installation process offered. This allows you to print from the new Win8 laptop without installing it like it was a new printer you bought today.
2. If the above doesn't work, try a full install using the USB cable and the CD if you have it. I have downloaded the drivers many times and it's always a troublesome install, whereas the CD seems to just work.
But back to what I said earlier - mine has several times nearly gone through the window. Try the suggestions, and breathe...
Hopefully that might help.
