A printing apparatus includes a holder configured to hold an expendable supply attached thereto, a print engine configured to perform printing using the supply, a display configured to display information regarding the supply, and a controller configured to determine whether a supply-consumed status amount of the supply attached to the holder has reached a first threshold, the supply-consumed status amount representing how much the supply is consumed, and when determining that the supply-consumed status amount of the supply attached to the holder has reached the first threshold, cause the display to show supply-related information related to a contract concluded on the supply used for the printing.
