I have an HP Envy 7800 series printer that is not enrolled in Instant Ink and it works just fine. HP asked me once during driver installation to subscribe to the subscription service, I said no, and it has not asked me again. One technical advantage HP has over Brother is the printer head is integrated into the cartridge. I previously owned an expensive Brother office inkjet printer and the printer head got into a bad state where no matter how many times I cleaned the head or replaced ink I had streaks. Another issue with Brother is it would not let me print black and white if I did not have color ink installed (HP does). Compared with the Epson EcoTank is there is an unused ink reservoir (called an ink pad) that will collect ink during cleaning cycles and other operations. Once this reservoir is full the printer has reached end of life (and Epson does not recommend servicing it). The EcoTank is really expensive as well.
