Printing Problem with Epson Expression XP-410

I have just finished setting up my new printer (to the best of my knowledge which isn't so great as it's my first printer)
I am trying to print from my Samsung Chromebook, which uses google cloud print. The printer is cloud print ready. I have no idea what I did wrong or just haven't done a necessary step or two.
Thanks for any help you can give me.
