ABSTRACT:
A printer having a device for advancing and retracting a print head toward and away from a paper supporting platen, an automatic head gap adjusting device for controlling the head advancing and retracting device, to advance the print head until the print head comes into contact with a recording paper, and then retracting the print head by a predetermined distance, to thereby adjust a head gap between the paper and the print head, and an operator-controlled head gap adjusting device for manually operating said head advancing and retracting device, to thereby adjust the head gap. A mode selector is provided for selecting one of an automatic adjusting mode in which the head gap is adjusted by the automatic head gap adjusting device, and a manual adjusting mode in which the head gap is adjusted by the operator-controlled head gap adjusting device.
