Abstract
A printer includes a conveyor to convey a tape having a plurality of marks in a conveyance direction, the marks including a first mark, and a second mark formed downstream of the first mark in the conveyance direction, a print head to print an image on the tape, a reflection sensor to detect the marks on the tape by emitting light toward the tape and receiving reflected light from the tape, and output a detection signal according to the reflected light when detecting the marks, and a controller. The controller is configured to set a threshold to be variable based on a level of the detection signal when the reflection sensor detects the second mark, and identify a position of the first mark based on a result of comparison between the threshold and a level of the detection signal when the reflection sensor detects the first mark.
