I love laser printers. I have a brother HL-5170DN which has built-in networking (so all computers in the house can use it) and auto-duplexing (print both sides w/out having to go switch out paper and turn it around). I think I paid $200 for it... which is a lot compared to sub-$70 ink jet printer... BUT after more than 4 years we are still on the original toner cartridge (and they apparently come with "starter" cartridges). We used to have to buy ink jet cartridges every few months for $50/pop, so in the long run, if you print mostly text, it's a much, much, much better deal. I'm also happy with this model because brother provides linux drivers, too.
It prints text in any size, it can also print pictures but they don't look good. It's b&w only, not for photos. They have color laser printers but they were much more than I wanted to pay at the time.
