The best printer decision I've ever made is my current printer, an HP OfficeJet 8620 with an ink subscription program. This HP has printed 9620 trouble-free pages since I purchased it a bit over two years ago (May, 2016). Yes, the per-page cost is relatively expensive, but it's the least hassle I've ever had with a printer. New ink just magically shows up in the mail shortly before I need it and I mail the old cartridges back for recycling. I haven't heard "honey/dad, the printer is broken/jammed/out-of-ink/won't-print again" since I purchased it.
My first printer was an Apple thermal printer, my second an Epson MX 100, so I've dealt with _a lot_ of printers over the years, from Apple, Epson, Canon, Brother, HP, and maybe other brands I'm forgetting.
I previously tried things like bulk ink tanks and refilling toner cartridges. Not worth the hassle.
I'm glad you're happy with your Brother. Mine had great initial reviews, but then when I checked back on Amazon a year later other folks has the same fuser roller issue:

Maybe it was specific to that model (HL-3170CDW). I don't know.
