• and
• a controller configured to set a feeding speed of a first print region on which coded first print information is printed to a second feeding speed that is slower than a predetermined first feeding speed, and to set a feeding speed of a second print region on which second print information other than the coded first print information is printed to the first feeding speed, the print medium including the first print region and the second print region,
• the controller in operation setting the feeding speed of the second print region on which the second print information is printed, the second print information being arranged with the first print information in a width direction of the print medium, the second print information including a portion partially extending from the first print region on which the first print information is printed, the first print information being arranged with the second print information in a lengthwise direction of the feeder body, among a plurality of second print information, to the feeding speed of the first print region on which the first print information is printed.
