An information processing device can communicate with a printer and a server. The printer includes a printing unit which carries out printing on a sheet with using a colorant. The server includes a server memory unit which stores user identification information and a print-permitted amount of printing permitted for a user in association with those. When a program is executed by a computer of the information processing device, the program causes the information processing device to perform display processing of displaying, a display unit of the information processing device, a selection screen for prompting the user to select a printing amount, and addition processing of, in response to a user's operation of the selection screen, causing the server to add the selected printing amount to the print-permitted amount associated with the user identification information of the user.
