Does anyone know what kind of machine is used to print posters? -

I am looking for a machine that is capable of printing posters/banners the size of 6 feet x 2 feet. The printing paper is the thin plastic sheets used to print poster.

Epson and HP both make printers capable of producing short runs. They will cost you a few thousands. The paper is expensive. The ink consumption is horrendous. Unless you are going into business, take your stuff to Staples, Office Max or a local printer.

A web press, about 75 thousand dollars
