yeah, unfortunately many people learn the hard way to not buy ink from retailHmmm I may ask her for the new one they sent for my own use, I don't print that often but buying ink at Walmart for that printer is just crazy expensive. That link you posted is waaayyy cheaper. I think she was paying like 80 bucks for a set? (I am not sure about the price but I know it was more than just a toner cart.)
The Wifi printing is just nice for her home set up, I would prefer wired myself (I will say being able to print from my Android device over WiFi is kinda slick... lol)
the ink for my lexmark was $70 at retail but remanufactored carts online cost about $10-15
For android printing I use printhand
