Abstract

Improved printers are disclosed which are characterized by means for inputting data which is arranged to function without the use of an alpha-numeric keyboard. The data inputting means may be a cursor moving device operating in conjunction with a graphics display system; a graphics display system having a touch-sensitive screen; a speech recognition unit; a memory or "smart card"; or an integral bar code reader. The cursor moving devices may be, for example, a tracker ball or a mouse.
