Note • If you have selected Auto with confirmation or Auto detect in the Media type selection method and you are using the barcode to manage the remaining roll paper, the barcode is read first. If it fails to read the barcode, it will detect the media type from the estimated result and display the candidate. • For details on media types that you can select, see "Paper Information List." • Adjusting the print head alignment with the type of paper to be used in printing may enhance printing quality.
