I am using refillables with an auto reset chip for this printer. It is printing good, however quite a different animal from the many Epsons I have had. While trial and error pushing buttons on the interface panel, I am concerned about Brother downloading a "fix" to something or a "updated driver" that may thwart the continued use of the refillables, and make them useless along with making the printer useless due to high cost of ink. What should I avoid doing to prevent printer manufacturer tactics? I have automatic updates turned off. \nWhat else, if anything can I do proactively to avoid Brother intrusion?
