Impossible to set up the printer

[KN7]

I just bought this printer the other day and it is giving me a million problems already....

So today I was tring to set up the instant ink online. it told me to follow the printed instructions and connect to the internet. method 1, mobile app,  i followed its instructions, connected to the printer, and returned to the hp 'smart' app, then the app still tells me to connect to the printer...... Fine, method 2 , connect the printer to my laptop with pre-installed hp 'smart' app and i had no idea where the 'hp folder', 'utility icon' or 'devices menu' is ----it tells me to find them in application folder, where i could only found hp smart icon..... Great, method 3, connected to router wps successfully and i tried to print the code it requires for the setup (by pressing info and cancle button simultaneously).however, it either gives me 'get the most out of your printer' or 'printer info page', no code at all. 

you can see how many times ive tried to make this **bleep** work from the photo i uploaded...it just kept printing useless instructions again and again..... and there are actually more pages than in the photo because i printed some on both sides just to save paper......

I haven't even printed anything and i have already lost lots of paper and ink. i regret a lot for buying this printer plus a set of *very expensive* ink cartages. i probably should have believed the one-star review on Argos saying 'this printer is impossible to setup' when i saw it last week.

although I have been complaining about this printer all the time (because it is legitimate **bleep**), I am still hoping that someone could give me a solution.....any help would be greatly appreciated, please.
