All you need to do is buy from a business that doesn't depend on fraud. Samsung make very nice and cheap black & white laser printers. I've bought two over the last few years, around $70. I see one on Amazon for $75 that has wifi printing as well), comes with a cartridge that lasted me 2-3 years and some thousands of pages, and replacement cartridges are $60 for branded ones, less than half that for generics. The printer is tiny, quiet, fast, etc. I can't believe people still buy anything else, after all we don't print photos at home much anymore, do we?

There are other manufacturers that do the same kind of model.

Just avoid HP and (in my experience) Canon. Laser is the way to go.
