ラベルプリンタ。 The platen and the printing head are connected so that they can be freely connected and separated.
A label end detection light emitting element that intermittently emits detection light for detecting the used state of a label passing between the printing head and the platen, and a label end detection light emitting element that emits light when the label end detection light emitting element is not emitting light. A head-up detection light-emitting element that emits detection light for detecting a state in which the printing head is separated from the platen is disposed on either the front side of the label or the back side thereof, and the head-up detection light-emitting element 1. A label printer characterized in that one light-receiving element for receiving detection light from the label end detection light-emitting element and detection light from the label-end detection light-emitting element is disposed on the other.
