Abstract
A printing device includes a head unit having a print head and a sensor that detects a presence or an absence of a sheet, a drive unit that causes the head unit to move to a width direction orthogonal to a feeding direction of the sheet, and a control unit controlling a position of the print head to the sheet based on a detection result of the sensor, wherein the control unit executes a first control that obtains the detection result of the sensor whenever the head unit moves only a first interval to a specific direction from a reference position and a second control that, when a change from the presence to the absence of the sheet is detected by the sensor during the first control, obtains the detection result of the sensor whenever the head unit moves only a second interval that is shorter than the first interval.
