If your Grandma is called Moses, then that's just what she needs.:)
Seriously, I replaced one A4 HP monochrome laser and two HP inkjets with one wirelessly networked printer which I could locate in the kitchen (easy to keep an eye on it, and that's where the coffee is kept). My model has two big paper trays and I can print a couple of hundred sheets before I have to "attend" to it. The ink tanks are clear, so I can check the levels as I walk past, and it's only a minute to pour some more ink in if needed. Full tank is 80 ml, or about four times what you get in a cartridge, so I never run out in the middle of a print run. To be honest, the A3 scanner is rarely needed, and I don't have or want a fax.
You can get ink system for most Epson printers so I guess you can probably get a similar set up with one of them, but I can only report my own experience, and that's with the Brother. A few people have bought similar set ups after seeing mine, and all are happy with the results.
As for picking up paper at an electronics store, you must be mad! Office supply if you want "photocopy" standard, but for decent prints to go on the wall in a frame you need acid free, Thank god Amazon does both, especially for those of us in rural areas. It is a major outing for me to go to my nearest "electronics store", takes at least an hour each way.
Yes most people don't put effort into printing, and boy does it show.
