Answer #2
I’ve got a Brother MFC 6490 CW all in one at home, and it’s not too bad for the price. Defo get one that takes compatible ink cartridges as A3 printers eat ink for breakfast. (I do more A3 scanning than printing though so you may be better getting just a printer if that’s all you need it for)
We do have HP ones in work, can’t remember the models, but they just get bought by the IT Dept from NHS suppliers – quality isn’t all that hot on them though.
