Abstract: A printer for printing in alpha-numeric character form information from a digital source available in the form of a video-type signal representative of alpha-numeric characters corresponding to the digital information. The printer utilizes a high speed rotating spindle having at least one spiral electrical conductor on its periphery and means for forming a mark on a continuous sheet of paper in response to an electrical signal applied to the spiral conductor. The paper is moved past the spindle at a velocity proportional to, but substantially less than the tangential velocity of the spiral conductor. The video-signal is received into a double buffer memory and unloaded to the spiral conductors in phase sequence with the rotation of the spindle whereby a matrix of dots is formed on the paper in designated locations so as to produce alpha-numeric characters corresponding to the digital information.
