Abstract
In a server system, the computer stores in the printer a usable print quantity in association with a printer in response to an increase request from an external device. The increase request is a request to store an increased quantity as the usable print quantity. The usable print quantity indicates one of the number of sheets and an amount of colorant which are usable for printing in the printer. The computer determines, after a communication interface is disconnected from the printer, whether a reconnection is established between the communication interface and the printer. The computer determines, when the reconnection is determined to be established, whether the usable print quantity has been reflected in data in the printer. The computer sends to the printer, when the usable print quantity is determined not to have been reflected in any data in the printer, a reflecting instruction to reflect the usable print quantity.
