Truth is you just never know. Over the last couple years I have sold 8-10 Brother all in one printers to clients. Bonus was factory ink was reasonable, and aftermarket ink carts seemed to work really well. Something changed about 6 months ago as aftermarket carts just don't seem to work anymore. I think the OEM cart manufacturer changed something. Firmware never changed.
Some aftermarket carts work fine. I have an old Epson R260 that I keep around for emergency photo printing, or for the rare DVD/CD printing. Been running on the same set of refillable carts for 6-7 years.
