A printer includes: a processor; a head configured to perform printing; a sensor configured to detect an amount of movement of the printer; and a scanner configured to acquire an image including a frame described on a material to be printed beforehand, the scanner being disposed forward of the head in a moving direction of the printer. The processor executes during scanning for frame detection over the material to be printed, frame detection processing to detect the frame based on the amount of movement and the image without performing the printing, and during scanning for printing over the material to be printed, print processing to perform the printing with the head based on the frame detected.
