The present application is based on, and claims priority from JP Application Serial Number 2020-012397, filed Jan. 29, 2020, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to a device management system, a server, and a method of controlling the device management system.

2. Related Art

JP-A-2016-045550 discloses the following printing consumable product management system. The printing consumable product management system determines whether or not a first consumable product is to be replaced by comparing consumable product information regarding consumption of the first consumable product of a printer with a first threshold value, and determines whether or not a second consumable product is to be replaced by comparing consumable product information regarding consumption of the second consumable product of the printer with a second threshold value when it is determined that the first consumable product is to be replaced. When it is determined that the second consumable product is to be replaced, the printing consumable product management system instructs delivery of the first consumable product and the second consumable product. In the printing consumable product management system, when it is determined that the first consumable product and the second consumable product are to be replaced, the first consumable product and the second consumable product are delivered together, and it is possible to reduce the delivery cost of the consumable products compared with a case where the first consumable product and the second consumable products are separately delivered.

In JP-A-2016-045550, whether or not a consumable product is to be replaced is determined only by comparing consumable product information with a threshold value, and consumption of a consumable product is not predicted. Therefore, the delivery cost of the consumable product is not sufficiently reduced.

SUMMARY

According to an aspect of the present disclosure, a device management system includes a storage control section storing, in a storage section, relationship information that indicates a relationship between attribute information indicating an attribute of a user of a device and consumption information indicating consumption of a consumable product of the device, an acquisition section acquiring the attribute information of a first user, and a predicted consumption calculation section calculating, based on the attribute information of the first user and the relationship information, predicted consumption of the consumable product of the device used by the first user.

According to another aspect of the present disclosure, a server includes a storage control section storing, in a storage section, relationship information that indicates a relationship between attribute information indicating an attribute of a user of a device and consumption information indicating consumption of a consumable product of the device, an acquisition section acquiring the attribute information of a first user, and a predicted consumption calculation section calculating, based on the attribute information of the first user and the relationship information, predicted consumption of the consumable product of the device used by the first user.

According to still another aspect of the present disclosure, a method of controlling a device management system causes a computer to perform causing a storage section to store relationship information that indicates a relationship between attribute information indicating an attribute of a user of a device and consumption information indicating consumption of a consumable product of the device, acquiring the attribute information of the first user, and calculating, based on the attribute information of the first user and the relationship information, predicted consumption of the consumable product of the device used by the first user.
