  • Patent number: 9405940
    Abstract: A printer and a control method of a printer can print barcodes appropriately according to a given print medium by means of a simple, easy operation. The printer stores a constant preset value relationally corresponding to each type of print medium. The printer also stores an added correction value that is optionally input for each specific type of print medium. The constant value and the added correction value are used to adjust the printed state of the barcode, e.g. to adjust bar widths within the barcode. The print control unit prints barcodes using the constant value stored in the printer storage unit adjusted with the added correction value.
