A server comprising: a remaining amount information receiving unit configured to receive repeatedly remaining amount information related to a remaining amount of color material in a first color material cartridge from a printer on which the first color material cartridge is mounted, wherein the printer is configured to execute a printing process by using a color material cartridge; an outputting unit configured to output shipping instruction data in a case where the remaining amount information is received from the printer and the remaining amount of the color material in the first color material cartridge indicated by the remaining amount information satisfies a predetermined condition, the shipping instruction data being used to ship a second color material cartridge to be mounted instead of the first color material cartridge; and a first sending unit configured to send specific information to an external device in a case where the remaining amount information is received from the printer and the remaining amount of the color material in the first color material cartridge indicated by the remaining amount information is equal to or less than a first remaining amount threshold, wherein the specific information is for changing a state of the printer from a state in which the printing process using the second color material cartridge is restricted to a state in which the printing process using the second color material cartridge is permitted in a case where the specific information is obtained by the printer in response to the specific information being sent to the external device wherein the outputting unit is configured to output the shipping instruction data in a case where first remaining amount information is received from the printer and the remaining amount of the color material in the first color material cartridge indicated by the first remaining amount information satisfies the predetermined condition, characterized in that in the case where the first remaining amount information is received from the printer and the remaining amount of the color material in the first color material cartridge indicated by the first remaining amount information satisfies the predetermined condition, the first sending unit is configured not to send the specific information and in a case where second remaining amount information is received from the printer after the shipping instruction data has been outputted in response to receiving the first remaining amount information from the printer and a remaining amount of the color material in the first color material cartridge indicated by the second remaining amount information is equal to or less than the first remaining amount threshold, the first sending unit is configured to send the specific information to the external device. a remaining amount information receiving unit configured to receive repeatedly remaining amount information related to a remaining amount of color material in a first color material cartridge from a printer on which the first color material cartridge is mounted, wherein the printer is configured to execute a printing process by using a color material cartridge;
