  • Publication number: 20220063306
    Abstract: A printing apparatus includes a plurality of set units to set rolled print media, a conveyance unit to convey the print media, a printing unit, a detection unit, and display units. The printing unit prints an image on the print media conveyed by the conveyance unit. The detection unit detects whether any one of the print media is fed to a predetermined printable position at which printing is performable by the printing unit. Each display unit is provided on a different one of the plurality of set units and configured to indicate whether a print medium set in a corresponding set unit is being fed. When the printing unit performs printing on the print medium, each display unit indicates whether the print medium set in the corresponding set unit is being fed in accordance with a result of detection performed by the detection unit.
