Remember I am in the Smart HP app - so an error telling me I needed to use the SmartHP app was unhelpful.I googled HP+ and this is apparently a printer where it was already registered and didn't need a code.

But no - on entering the code (which looked exactly like the code it said I needed) I was told that this was a different type of printer (see image) - I had an HP+ which had to be registered through the SmartHP app. I'd read about this in the reviews and handily it had printed out earlier so I had this. The last stage was to enter the printer code. All my details in, credit card etc, added the FREEINK code for an extra month. So I tried with my laptop - as really I would want to print from there anyway.After downloading the Smart HP app and linking the printer, I was then able to click the instant ink button and be told I was entitled to the free trial. Note this has to be activated within 7 days of registering your printer to get the free trial, so I was keen to get it set up.First try using an iphone - following set up of the printer I wasn't offered anything re the free trial, just told an issue with the registration had occurred. The printer quality is fine for a sub £50 printer and speedy enough for the odd work document and personal admin that I'm using it for.The real hassle came from the instant ink subscription. Code for an extra month of free instant ink 5ckft1.The printer itself was up and running on the first attempt (15-20 mins depending on how long your wi-fi password is).

Settle in and try switching it off and on again.

Like others I read the reviews and was worried it would be glitchy to set up.TL DR - It is glitchy and the UX is pretty bad. Reviewed in the United Kingdom on 23 April 2021
