ABSTRACT:
A single-beam CRT printer, used as a validator record of electrocardiographic data played back from a magnetic tape at a much higher speed than the speed at which it was recorded, includes a scan circuit for generating signals for steering the beam alternately through an ECG scan pattern and through a character scan pattern and further includes a character generator for modulating the intensity of the beam in relation to the instantaneous location of the beam within the character scan pattern to cause the beam to print characters, the intensity of the beam and its linear velocity being increased during execution of the character scan pattern to permit the characters to be printed at such a high speed that only an insignificant part of the ECG plot is omitted while the characters are being printed.
