Printing document maybe is almost as important as working on it. Although sometime we only work with softcopy of documents, hardcopy can be required once in a while. Beside that, printed documents can be more handy, flexible and easy to read. Choosing printer that fit to is really depend on what you need.
I prefer printer that has economic value. Epson printers need original ink, and it makes them not economic, but there are lots of people modified this printer with ink-tank system.
