• a lighting unit provided on the inner side of the support portion for each region of the support portion;
• a light transmitting portion configured to transmit light emitted by the lighting unit to the outer side of the support portion;
• a printing unit configured to perform printing on the medium supported by the support portion;
• and
• a control unit configured to control the lighting unit, wherein
