*EDIT:*

So in my SMART APP it says 2208JR but on the paper it's printing, it says 2251D. This is so weird. Also, in my app it looks like it's all out of ink but on the website it's full.

Okay, I'll try this, but I can't do it at the moment as my only Windows PC doesn't have wifi and I can't connect to the IP of the printer. 

However the newest firmware update says 2251D while my firmware version says TOP1FN2251DR. Believe it's the same? 😕
