A printing apparatus performing printing by applying a printing liquid onto a printing medium, the printing apparatus comprising a notification device,

• wherein the notification device includes:
• an acquisition unit that acquires information relating to a residual amount of each of a plurality of supplied printing liquids;
• a determination unit that determines whether or not each of the plurality of printing liquids is a printing liquid of a notification target of which a residual amount is a predetermined amount or less based on the information acquired by the acquisition unit;
• and
• a notification unit that, in a case where a plurality of printing liquids of the notification target determined by the determination unit are present, notifies of information relating to the residual amount of a predetermined printing liquid satisfying a predetermined condition among the plurality of printing liquids of the notification target,
• wherein the predetermined amount includes a first predetermined amount and a second predetermined amount greater than the first predetermined amount,
• wherein the determination unit determines whether or not each of the plurality of printing liquids is a printing liquid of a first notification target of the first predetermined amount or less and determines whether or not each of the plurality of printing liquids is a printing liquid of a second notification target of the second predetermined amount or less, and
• wherein the notification unit, in a case where a plurality of printing liquids of the first notification target determined by the determination unit are present, notifies of the information relating to the residual amount for a predetermined printing liquid satisfying the predetermined condition among the plurality of printing liquids of the first notification target with priority and, in a case where a plurality of printing liquids of the second notification target determined by the determination unit are present, notifies of the information relating to the residual amount for a predetermined printing liquid satisfying the predetermined condition among the plurality of printing liquids of the second notification target with priority.
