Abstract
A printer including a gap changeover device for moving a print head and a platen relative to each other and thereby adjusting a head gap between the print head and a recording medium on the platen. A switch is provided to produce a signal where the recording medium includes a local portion whose thickness is greater than that of the remaining portion. A gap control device is responsive to the signal from the switch, to change a normally established head gap to a larger value. At the same time, a speed control device is operated to lower the printing speed, according to the larger head gap.
