I don't hate all printers, but I viscerally hate HP printers. They have all of the anticonsumer bullshit. I won't even buy other HP products (laptops) because I had such a bad experience with their shitty printers.
Brother's laserjets are great, I use one at home now. My most reliable printer was actually an old Samsung monocolor laser printer, lasted 10 years before kicking the bucket.
Edit: such is my hatred for HP printers that I would volunteer to smash all of them in my free time. HP printer genocide is warranted.
