as for if really there's cash only ticket dispenser, I dun think
e dot matrix and thermal printer size would have much diff... only
thing maybe they went for thermal is cos it's very cheap
but but, it's going to burn a big hole in e long run cos e
ticket paper for thermal printer is dunno how many times more ex
than dot matrix printer paper 
Think of it in the good way, they don't need to buy ink. which
saves them money overall.
